The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified from testing envelope high pressure water injection packer.
A kind of from testing envelope high pressure water injection packer; Comprise top connection 1, central tube 2, top seal device, locking device, sealer, lower contact 25; Said top connection, lower contact are respectively through being threaded in the upper/lower terminal of central tube; Central tube between top connection and the lower contact is installed top sealing device, locking device and sealer outward successively, and the maximum outside diameter of said top connection is greater than the maximum outside diameter of other each parts.
The top seal device comprises the positioning sleeve 3 that is installed in outside the central tube; Install glue tube base 4 between this positioning sleeve and the central tube; Sealed inner tube 26 engagements are installed in the glue tube base lower end; Be shaped on the pressure transmission hole that aligns with central tube top on the pipe in the sealing, the outer elastic packing assembly of installing of pipe in the sealing, this elastic packing assembly is made up of leather cup ring 5, high pressure leather cup 6, packing element ring 7, packing element 8, packing element ring, high pressure leather cup, the leather cup ring installed successively; Glue tube base 9 during said elastic packing assembly lower end connects, glue tube base is installed in outside the sealed inner tube in this.
Locking device comprises the retainer ring 10 that is welded on the sealed inner tube outer wall, and the sealed inner tube of this retainer ring lower end is installed lock sleeve 11 outward, and binding ring 12 is installed in this lock sleeve external toothing; This binding ring lower end installs the baffle ring 13 that is sealed and matched with middle glue tube base; The installation elastic packing assembly of said lock sleeve lower end, lower rubber cylinder seat 15 14 is fixed on the sealing inner core through pinning, and divides claw 17 through being threaded in sealed inner tube 26 lower ends; Dividing claw to overlap 16 upper ends is connected with lower rubber cylinder seat 15 through screw thread; Separate lock ring 18 and be connected with central tube 2 through screw thread, the said lock ring upper end of separating is shaped on conical socket, and the pawl end of said minute claw may be collapsed to release and changes in the made conical socket; Lock dog cover 19 is installed in the central tube outside, and this lock dog set upper side is overlapped 16 lower ends through screw thread with the branch claw and is connected.
Sealer comprises shear pin 20, piston 21, lock dog 22, sliding sleeve 23 and urceolus 24; Said urceolus upper end is connected with said lock dog cover middle part through screw thread; In the cavity that forms piston is installed between the two, this piston is connected through shear pin with said urceolus, and said lock dog has put the lock dog groove and in this lock dog groove, lock dog has been installed; The lock dog cover is fixed on the central tube through lock dog; When seat does not seal, the pressure transmission hole that make this lock dog shutoff central tube bottom, said sliding sleeve is installed in the cavity lower end between urceolus and the central tube.
Said high pressure leather cup is a bowl structure, and it is tight more that this structure can make leather cup under the high pressure effect, press more, thereby reach high voltage bearing purpose, and the material of said high pressure leather cup is a high-temperature resistant rubber, thereby makes it have heat resistance preferably.
On said positioning sleeve, last glue tube base, high pressure leather cup, middle glue tube base, retainer ring, lock dog cover, piston, the sliding sleeve seal groove is arranged all, inside is equipped with " O " RunddichtringO.
The concrete course of work of the utility model is:
During work, sealing drum is lowered in advance the well section that needs sealing.To test envelope high pressure water injection packer certainly is lowered in the pit shaft through sending into tubing string; Each part of packer passes through sealing drum successively; Because the top connection maximum outside diameter is greater than the sealing drum minimum diameter; Make packer need be positioned the sealed well section no longer descending, the leather cup ring on packer top, high pressure leather cup, packing element ring, packing element all are arranged in the sealing drum inner chamber.
Packer is suppressed, shear pin is cut off, piston stroking upward, lock dog lose support and fall, the packer release, and force urceolus, piston, lock dog overlap branch claw cover, the lower rubber cylinder seat is up, thus the high pressure leather cup and the packing element of compression packer bottom.After dividing claw to put row, the box of its underpart meshes locking with dividing the pin thread on the claw pawl end, can prevent packer sealer deblocking.Simultaneously, pressure is up through glue tube base in the pressure transmission hole promotion on packer top, thus the high pressure leather cup and the packing element on the compression packer top that makes progress.It is up that middle glue tube base drives binding ring, makes binding ring and lock sleeve engagement locking, can prevent packer top seal device deblocking.Whether when two groups of sealing device seats envelopes up and down finish, the pressure transmission hole through central tube top continues to suppress, and pressure liquid gets into to be expanded by two groups of sealing devices up and down and is honored as a queen in the closed chamber that forms, check packer to seal successfully thus, referring to Fig. 3.So far packer set, certainly test the envelope finish, can carry out the water filling operation.
Need the upper lifting pipe post during deblocking, drive central tube and separate lock ring up, divide the pawl end of claw to shrink the inner chamber of into separating lock ring, separate with a minute claw cover, locking device lost efficacy, the packer deblocking, thus can pit shaft be proposed packer.
Above-described examples of implementation are one of specific embodiment of the utility model, and the common variation that those skilled in the art carries out its profile, structure and compound mode etc. all should be included in the protection domain of the utility model.
