Abstract
The utility model discloses a pump-followed pressure and temperature test device used in petroleum industry for pumping units for oil production wells, particularly for thickened oil wells, and aims to solve the difficulty that the conventional tester cannot record the continuous long-term dynamic pressure and temperature in the entire oil production process and recovered data of the later stage of steam injection-stimulated wells or mechanical oil production wells, so as to provide important dynamic monitoring and analyzing data for dynamic analysis of the oil wells. The device comprises a tester which is mounted in a fixed mechanism, the casing of the fixed mechanism is provided with a pressure transmitting hole, and the device is connected below an oil well pump and is then descended into the well with a downhole string. The device effectively solves the difficulty that the conventional tester cannot record the continuous long-term dynamic pressure and temperature in the entire oil production process and recovered data of the later stage of steam injection-stimulated wells or mechanical oil production wells. In addition, the device with good anti-shock property, convenient connection and simple structure can meet the test requirements of pressure recovery and interference testing.
Description
Technical field
The utility model relates to the down-hole pressure temperature test facility of petroleum industry, particularly with pump pressure temperature test device, is used for the pumping production well, is particularly useful for heavy oil wells.Solve the handle up admission of recovery data in continuous long-term dynamics pressure, temperature and later stage in well or the whole oil recovery manufacturing process of machine-pumped oil well of heavy crude reservoir steam injection that the conventionally test instrument can't implement, for WPA provides important dynamic monitoring analysis of data.
Background technology
At present, non-heavy oil wells temperature under the straight well condition, pressure test technology are ripe, and the heavy crude reservoir steam injection is handled up well and machine-pumped oil well because down-hole string complex structure, influence of various factors such as in-place oil viscosity is big and the hole deviation degree is big, and the temperature, pressure data of such well is difficult to admission.Be subjected to viscosity of crude and the big influence of hole deviation degree, even if such well has been installed decentralized wellhead, the conventionally test instrument also is difficult to test to target zone down smoothly by cable or steel wire; Play the pump manometric method since during operation in kill-job and the operation process pressure measurement stand-by period not enough, cause test data can not react temperature, the pressure truth on stratum truly, the admission that pressure recovers data more is difficult to realize.The problems referred to above cause the dynamic means of production famine of such well whole oil well in the oil recovery manufacturing process, can not satisfy the needs of oil field reasonable development.Be subjected to invent very necessary with pump pressure temperature test device in order to address this problem.
Summary of the invention
The purpose of this utility model provides with pump pressure temperature test device, solve the handle up admission of recovery data in continuous long-term dynamics pressure, temperature and later stage in well or the whole oil recovery manufacturing process of machine-pumped oil well of heavy crude reservoir steam injection, for WPA provides important dynamic monitoring analysis of data.
The purpose of this utility model is achieved in that with pump pressure temperature test device and comprises tester that tester is installed in the fixed mechanism, and the housing of fixed mechanism is provided with pressure transmission hole.This device is connected the below of oil well pump, in the down-hole string lower going-into-well.
Compared with prior art the utlity model has following useful effect: this device has solved the handle up admission difficult problem of recovery data in continuous long-term dynamics pressure, temperature and later stage in well or the whole oil recovery manufacturing process of machine-pumped oil well of heavy crude reservoir steam injection that test mode routinely can't implement effectively.This device is selected the memory-type pressure temperature measuring device for use, is lowered in the target zone with oil well pump.The housing of fixed mechanism is provided with pressure transmission hole, and strata pressure, temperature signal are delivered to tester by pressure transmission hole.The two ends design connector of tester is fixed in the housing by damping spring.The corrosion-resistant class machine oil of liquid storage intra-bladder instillation, the reduction tubing string removes the bump to tester.It is good that this device has anti-seismic performance, easy to connect, simple in structure, satisfies the test request of pressure recovery and interference test, and tester can be in the down-hole continuous operation more than 1 year.Solved the handle up real-time admission and the long-term continuous monitoring of pressure and temp of well or the whole oil recovery manufacturing process of machine-pumped oil well of heavy crude reservoir steam injection.Especially solve handle up well or machine-pumped oil well pressure of heavy crude reservoir steam injection and recovered the difficult problem that data can't be enrolled.During when needs are understood strata pressure, temperature parameter or at pump detection and workover, trip out, connect the ground playback apparatus, read data with pump.Data information comprehensively, true, real time record all pressure, variation of temperature situation in the entire work process.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples: referring to accompanying drawing, comprise tester 7 with pump pressure temperature test device, tester 7 is installed in the fixed mechanism that the housing 6 of fixed mechanism is provided with pressure transmission hole 4.Tester 7 is memory-type pressure temperature test instruments.The two ends of tester 7 are connected with 8 with connector 3 respectively, connector 3 and 8 outside cutting ferrule damping spring 2 and 9.Fixed mechanism comprises housing 6 and starting taper 10, and housing 6 is connected with starting taper 10, is provided with spring base at the interior top of chamber of housing 6, and damping spring 2 is installed; Intracavity bottom at starting taper 10 is provided with the spring mounting groove, and damping spring 9 is installed.Housing 6 and starting taper 10 are connected to form liquid storage cylinder 5.Perfusion machine oil in liquid storage cylinder 5, as: the extraordinary finish of stainless steel, lithium agent fat.Reduce tubing string and remove the bump that tester 7 is caused.Corresponding pressure transmission hole 4 is provided with filter screen on the housing 6, prevents that gravel from entering liquid storage cylinder 5.The bottom cylindrical of starting taper 10 is pyramidal structures, helps going into the well of this device.The top cylindrical of housing 6 be connected hoop 1 and connect, also can manufacture with housing 6 integral body, as long as at the top design connection chamber of housing 6 connecting hoop 1.Be connected with oil pipe below the oil well pump connecting the connection chamber at hoop 1 or housing 6 tops, this device be installed in the below of oil well pump, with running string down to target zone.Just weave the test program of tester 7 before going into the well, promptly begun work after going into the well according to the production purpose.Realize the heavy crude reservoir steam injection handle up well or the whole oil recovery pressure in production process of machine-pumped oil well Temperature Datum in real time, the admission of long term monitoring and the recovery data in later stage continuously.When needs are understood pressure, the temperature parameter on stratum, carry pump with this device taking-up ground, perhaps when pump detection and workover, trip out with pump.After the taking-up, unload starting taper 10, tester 7 can be taken out from housing 6, connect the ground playback apparatus, read data.
