The specific embodiment
Embodiments of the invention shown in Fig. 1-13 are a pipe conveying well measuring assembly 10.This assembly 10 comprises a tubing string 12, and for example coiled tubing or drilling pipe bar are connected on the delivery assembly 20 of delivery memory logging tool 24.When needs are logged well, can the ground 14 by underground oil and gas pit shaft 16 on suitable ground installation 18 drive tubing strings 12 and wish the positions of logging well in the pit shaft 16.This driving of tubing string 12 allows assembly 10 to use in the pit shaft of the well logging operating mode (TLC) of difficulty.
Yet transport assembly 10 required driving forces may be broken the memory logging tool 24 fragile relatively to external force easily into pieces.Therefore, when assembly 10 was driven into need log well regional at full tilt, memory logging tool 24 was protected in delivery assembly 20.The above-mentioned protective position of memory logging tool 24 is arranged in the delivery assembly 20, referred to herein as retracted position (for example shown in Figure 5).
As described below, when arriving the position that needs well logging, memory logging tool 24 can eject from delivery assembly 20, makes memory logging tool 24 stretch out from the bottom of delivery assembly 20.The above-mentioned ejected position of memory logging tool 24 is referred to herein as extended position (for example shown in Figure 9).At extended position, memory logging tool 24 can begin its memory well logging work.
In order to highlight the internal construction of pipe conveying well measuring assembly 10, Figure 2 shows that the memory logging tool of separating from delivery assembly 20 24.As shown in the figure, memory logging tool 24 is connected with allotment 22.In an embodiment, rotatable erecting device, for example low torque swivel coupling 26 is used for connected storage logging tool 24 and allotment 22.By above-mentioned connection, allotment 22 can be as shown in arrow 28 be rotated around longitudinal axis with respect to memory logging tool 24.Therefore, under the situation that allotment 22, delivery assembly 20 and tubing string 12 rotate together, it is static that memory logging tool 24 can keep.Torque can not be delivered on the memory logging tool 24 when in other words, turning swivel coupling 26 permission tubing strings 12 and 20 rotations of delivery assembly.
Still shown in the enlarged drawing of Fig. 2 and Fig. 3 and following further describing, allotment 22 comprises having the collet chuck 30 of radially movably locking pawl 32.These lock pawls 32 are combined with the part of delivery assembly 20, and memory logging tool 24 is fixed tightly in foregoing retracted position or foregoing extended position.Still shown in Fig. 2-3 and following further describing, seal 34 extends from the external surface of allotment 22.In addition, in an embodiment, fishing neck 25 is connected to the upper end of allotment 22, and its meaning will be in following description.
Still as shown in Figure 2, memory logging tool 24 comprises battery 21.Battery 21 can be operated in the logging operation process, for memory logging tool 24 provides power.Memory logging tool 24 can also comprise memory module 23, gathers and store the log data that is obtained by memory logging tool 24 in the logging operation process.The method of fetching the log data of being gathered by memory module will be in following description.
Figure 4 shows that the rough schematic of delivery assembly 20.As shown in the figure, delivery assembly 20 comprises inner housing 36 and shell body 38.In an embodiment, inner housing and shell body 36,38 can be the cylindrical-shaped structure basically that arranges with one heart respectively.In an embodiment, shell body 38 tops comprise connecting the union 55 of tubing string 12; The bottom of shell body 38 comprises guide plate 65.Guide plate 65 can comprise the reamer section of trough of belt.In an embodiment, union 55 comprises that interior profile admits flap valve under the pump, and this flap valve can be installed in advance in advance, as the service valve of pre-well blowout preventing.What it should be noted that the left side dotted line of the memory logging tool 24 among Fig. 4 represents is the retracted position of memory logging tool 24, and what the right side dotted line of the memory logging tool 24 among Fig. 4 was represented is the extended position of memory logging tool 24.
As following detailed description, inner housing 36 comprises and ejects assembly 40, receiving unit 44 and transitional region 42 between them is set.Here simple the description and following detailed description ejected assembly 40 and comprised that the top latch is used for memory logging tool 24 is remained on retracted position, and receiving unit 44 comprises that the bottom latch is used for memory logging tool 24 is remained on extended position.
Figure 5 shows that the memory logging tool 24 at retracted position.Fig. 6 A-6B is depicted as the amplification of the part of Fig. 5.Shown in Fig. 6 A-6B, eject the part that assembly 40 forms delivery assembly 20 inner housings 36.The inner surface that ejects assembly 40 comprises and an allotment profile (described herein is top latch profile 50) that 22 lock pawls, 32 outlines match.Therefore, when the lock pawl 32 of allotment 22 cooperated with the top latch profile 50 that delivers assembly 20, memory logging tool 24 was tightened securely at retracted position.
Figure 9 shows that the memory logging tool 24 at extended position.Figure 10 shows that the guide wire of alternative shape of Fig. 9.As shown in figure 10, receiving unit 44 forms the part of delivery assembly 20 inner housings 36.The inner surface of receiving unit 44 comprises the profile (referred to herein as bottom latch profile 52) that matches with the outline of allotment 22 a lock pawl 32.Therefore, when the lock pawl 32 of allotment 22 cooperated with the bottom latch profile 52 that delivers assembly 20, memory logging tool 24 was tightened securely at extended position.
Fig. 6 A-8 is depicted as according to an embodiment of the invention, and how memory logging tool 24 moves to extended position from retracted position.As shown in Figure 6A, piston 54 forms the top of ejecting assembly 40.What rotatably center on the installation of piston 54 external surfaces is valve module 56.Yet valve module 56 also comprises the projection that extends internally 58 that cooperates with the groove 60 that extends of circumference on piston 54 external surfaces 62, and like this, valve module 56 can be vertically moved (still shown in Fig. 6 C and 8) by piston 54.
Shown in Fig. 6 A was further, the external surface 66 of valve module 56 comprised " J-shaped " groove 64 (still referring to Fig. 6 C and 7) that a circumference extends.Stationary pin 68, for example the dog screw that extends radially inwardly from the shell body 38 that delivers assembly 20 matches with " J-shaped " groove 64.Therefore, will describe in detail below, piston 54 vertically moves together with the shell body pin 68 that cooperates with valve " J-shaped " groove 64 and the valve projection 58 that cooperates with piston groove 60, makes 56 of valve groups rotatablely move and lengthwise movement with respect to piston 54.These motions make valve module 56 below with conversion between the open position (Fig. 6 A) that further describes and the fastening position (Fig. 6 B).
When pipe conveying well measuring assembly 10 is transported to the down-hole when the pit shaft 16 more and more deeply, the pit shaft static pressure of pipe conveying well measuring assembly 10 outsides increases gradually, has therefore produced huge pressure reduction between the external environment condition of the internal environment of assembly 10 and assembly 10.If this pressure reduction is too big, the internal parts in the assembly 10 will misplace and/or damage, when extreme pressure reduction, and assembly 10 itself even may subside or break.
Therefore, can produce that pressure reduction increases between the inside and outside environment that internal pressures stop assembly 10 in that assembly 10 is inner.This internal pressure can produce by assembly 10 pumping circulation fluids.Above the ground installation of describing 18 can be comprised pump, be used for providing this circulation of fluid to assembly 10.
Therefore, when pipe conveying well measuring assembly 10 was transported to the position that need log well the down-hole, valve module 56 typically remained on run location in open position among Fig. 6 A or the hole, to allow circulation of fluid pumping thus.It should be noted that the open position at valve module 56, hole 72 fluids of piston 54 connect the endoporus 48 of inner housing 36 to the annular space 46 between delivery assembly 20 inner and outer shells 36,38.Therefore, when valve module 56 during at open position, circulation of fluid allows along the path flow shown in the arrow 70.As shown in Figure 6A, when circulation of fluid was passed through assembly 10 pumpings, fluid was by piston hole 72 rather than continue descending along the endoporus 48 of inner housing 36.This is because formed the fluid sealing between the external seal 34 of the inner surface 74 that ejects assembly 40 and allotment 22.
Therefore; when memory logging tool 24 at retracted position; inner housing 36 protections by delivery assembly 20; and valve module 56 is when open position; do not allow circulation of fluid to enter the endoporus 48 of inner housing 36 (memory logging assembly 24 is arranged on this); but allow via the annular space 46 between the inner and outer shell 36,38 by assembly 10.Therefore, when circulation of fluid flows by assembly 10, do not allow its contact memory logging assembly 24.Therefore, circulation of fluid any clogged with fragments or the corrosiveness that may influence memory logging tool 24 avoided.
In addition, it should be noted that when valve module 56 is shown in an open position, allow circulation of fluid to flow with the moving path 70 of the longshore current that makes progress downwards.That is to say that when valve module 56 was shown in an open position, forward flow and the reverse flow of circulation of fluid all allowed.
With reference to piston 54 before and the interaction (shown in Fig. 6 A-8) of valve module 56, piston 54 is compressed for example fexible bias pressure of spring of parts 76 in last well direction.When the endoporus 48 of inner housing 36 and the pressure reduction between the annular space 46 between the inner and outer shell 36,38 hour, spring 76 do not compress and piston 54 static.Yet the pressure reduction between endoporus 48 and the annular space 46 has surpassed default pressure differential limit P
1, cause spring 76 compression, allow piston 54 vertically to move downward with respect to allotment 22.
Surmount above-mentioned pressure differential limit P
1Can realize like this: be in when opening at valve module 56, the pump on the operate ground device 18 increases the flow of circulation of fluid, perhaps is at valve module 56 and closes and circulation of fluid when static, increases the pressure of circulation of fluid simply.By same way as, the pump on the ground installation 18 can be used for producing other pressure reduction, other actions in the assembly 10 that is used for realizing describing below.
In an embodiment, valve module 56 moves between the opening and closing position shown in Fig. 6 A-8.In this embodiment, valve module 56 comprises three open position O
1-O
3With three fastening position C
1-C
3Yet as described below, in interchangeable embodiment, valve module 56 can include as few as an open position and a fastening position.
From open position O
1The motion of valve module 56 is described in beginning.In other words, at position O
1, valve module 56 is opened; Shell body pin 68 valve modules 56 are in the position O in " J-shaped " groove 64 in the external surface 66
1 Valve projection 58 is in the position O in the circumferential groove 60 in piston 54 external surfaces 62
1By surpassing pressure differential limit P
1, piston 54 vertically moves downward with respect to allotment 22 as mentioned above.Moving downward of piston 54 makes valve module 56 move downward because valve projection 58 remains in the piston groove 60.The moving downward of valve module 56 make shell body pin 68 along arrow 78 indication paths from position O
1Move to position T
1Though yet it is noted that " J-shaped " groove 64 allows piston 54 setover T
1Further vertically move downward, but piston 54 extended radially inwardly from shell body 38 cut off 84 the restriction, its meaning will be described below.
Because valve module 56 rotates freely with respect to piston 54, shell body pin 68 is from position O
1Move to position T
1Make valve module 56 rotate, produce the relative transverse movement (1/2L) between valve module 56 and the piston 54.Shell body pin 68 is parked in position T then
1Up to no longer surpassing limit pressure difference P default between endoporus 48 and the annular space 46
1Till.At this moment, spring 76 decompresses, and impels piston 54 vertically to move upward, so make shell body pin 68 along the path of arrow 80 indications from position T
1Move to position O
2When shell body pin 68 from position T
1Move to position O
2The time, valve module 56 rotations produce another the relative transverse movement (1/2L) between valve module 56 and the piston 54.Therefore, during " circulation " of valve module 56, (for example from position O
1To position O
2Circulation) valve module 56 moved a lateral separation L.
When each valve module 56 laterally moved, valve projection 58 was correspondingly laterally mobile in piston groove 60, and therefore, in one of valve module 56 complete " circulation ", valve projection 58 has laterally moved distance L with respect to piston 54.By alternately surpassing and being lower than limit pressure difference P default between endoporus 48 and the annular space 46
1, valve module 56 can be at each the valve position O shown in Fig. 7-8
1To O
3And C
1To C
3Between the circulation.
For example, when valve module 56 from position O
2To O
3Circulation time, valve module 56 makes valve projection 58 laterally move distance L with respect to piston 54 with respect to piston 54 rotation, as it from position O
1To O
2Shi Yidong's is such.Similarly, valve module 56 is from position O
3To C
1Circulation time, valve module 56 makes valve projection 58 laterally move distance L with respect to piston 54 with respect to piston 54 rotation, as it in front described two circulations.Yet, because the shape of piston groove 60, when valve module 56 from position O
3To C
1Circulation, and valve projection 58 has been when laterally having moved distance L with respect to piston 54, and valve module 56 vertically moves forward with respect to piston 54.This relative vertically moving makes the hole 72 (shown in the X mark 45 among Fig. 6 B) on valve module 56 interlocks or the closure piston 54.Therefore, the path 70 between endoporus 48 and the annular space 46 is closed, and valve module 56 is called as and is in fastening position.
When valve module 56 is in the closed position, stop circulation of fluid to enter annular space 46 between the inner and outer shell 36,38, change into and enter another flow path 82.Along this flow path 82, circulation of fluid mobile is arranged on 34 preventions of fluid sealing on allotment 22 external surface, and this fluid sealing 34 is in allotment 22 and eject the fluid-tight sealing of formation between the inner surface 74 of assembly 40.
Under the situation of valve module 56 C1 in the closed position, cutting off 84 (front was introduced) can be by valve module 56 from position C
1To C
2Circulation shear.That is to say, as the default pressure differential limit P that surmounts between endoporus 48 and the annular space 46
2, make piston 54 compression piston springs 78 and enough to cut off 84 the power of cutting off when vertically moving downward, cut off 84 and cut off by the end 81 of piston 54 and (to note, to cut off and cut off 84 needed pressure differential limit P
2Than the required pressure differential limit P of compression piston spring 78
1Greatly).
Cut off 84 by valve module 56 from position C
1To C
2The shuttling movement situation of cutting off under, the omnidistance lengthwise movement of piston 54 no longer is blocked; And work as valve module 56 from position C
2To C
3Circulation time, the extra lengthwise movement of piston 54 allow the shoulder 86 of the down-hole part of piston 54 connect on allotment 22 collet chuck 30 lock pawl 32 and with its radially inwardly compression.This radially inwardly compression of lock pawl 32 makes lock pawl 32 break away from from the top latch profile 50 of delivery assembly 20.
Along with the disengaging of lock pawl 32, flow through frictional resistance that endoporus 48 crosses allotment 22 of circulation of fluid makes allotment 22 (and therefore memory logging tools 24) transmit with respect to delivery assembly 20 downwards.This downward motion continues to arrive and be engaged on the bottom latch profile 52 of bottom or the receiving unit 44 of delivery assembly 20 up to the lock pawl 32 of allotment 22, as shown in figure 10.
In an interchangeable embodiment, memory logging tool 24 can be discharged by the retracted position of an electronic trigger from locking, for example any embodiment of the electronic trigger of describing in the United States Patent (USP) of submitting on March 4th, 2,008 7,337,850.
Notice that when memory logging tool 24 was in retracted position, the small diameter portion 86 of assemblies 40 inner surfaces 74 was ejected in sealing 34 contacts of allotment 22.When allotment 22 begins to move downward from the retracted position to the extended position, the inner surface 74 that ejects assembly 40 be opened into larger diameter 88 make sealing 34 no longer contact eject the inner surface 74 of assembly 40.Similarly, (that is, eject the part of the inner housing 36 between assembly 40 and the receiving unit 44) in the transitional region 42 of the inner housing 36 that delivers assembly 20, sealing 34 does not contact the inner surface of transitional region 42.Also with to eject assembly 40 similar, the inner surface 89 of receiving unit 44 comprise the enlarged 90 that do not contact sealing 34 and picture lock pawl 32 mesh engages and seals 34 the latch profiles 52 of bottom than minor diameter 92.
Therefore, when memory logging assembly 24 moves from retracted position to extended position, in case lock pawl 32 unclamps from latch side, top 50, then seal 34 and break away from from ejecting assembly 40 rapidly; When allotment 22 keeps breaking away from during laterally through transitional region 42; In case 52 lockings of lock pawl 32 and bottom latch profile, then mesh receiving unit 44 than minor diameter 92.Therefore, the quantity of the dynamic friction in the moving process from the retracted position to the extended position, experienced of seal 34 and seal 34 wearing and tearing that caused by these kinetic force of frictions and tear and reduce to minimum.
As shown in figure 10, hole 94 fluids of receiving unit 44 connect endoporus 48 and the annular space 46 of receiving unit 44.Therefore, when memory logging tool 24 is locked at extended position, circulation of fluid can by flow path 96 from endoporus 48 to annular space 46 flow through assemblies 10 and flowing out outside assembly 10 lower ends.
Notice that when memory logging assembly 24 is locked at extended position (as shown in figure 10), valve module 56 can be maintained in its closed position or it can be from position C
3To O
1Valve module 56 is opened in circulation.In fastening position, reverse flow only ends in valve module 56, because valve module 10 stops further reverse flow, shown in X mark 98 among Fig. 6 B.Therefore, the reverse flow in whole if desired assembly 10 scopes, valve module 56 can be from position C
3To O
1Circulation is to open valve module 56.Under the situation that valve module 56 is opened, the reverse flow of circulation of fluid allows to pass through assembly 10 according to flow path 70 as shown in Figure 6A.
Yet no matter valve module 56 is in open position or fastening position, fluid all can not allow from lock pawl 32 disengaging bottom latch profiles 52 by the reverse flow of assembly 10.That is to say that when memory logging tool 24 during at extended position, fluid can not allow memory logging tool 24 be withdrawn in the delivery assembly 20 by the reverse flow of assembly 10.
