Abstract
The utility model relates to an oily water drainage and recovery device for an oil field, in particular to a pipe column drainage pump for an oil well. The technical scheme is that the drainage pump comprises a connecting rod, a plunger assembly, a traveling valve assembly, a pump barrel assembly, a standing valve assembly and a lock sleeve. Oil pipe thread is arranged on the connecting rod. The plunger assembly, the pump barrel assembly and the lock sleeve can be connected with an oil pipe through the oil pipe thread on the connecting rod. The standing valve assembly and the traveling valve assembly are separately put according to liquor drainage requirement, and then the whole pipe column is assembled and anchored to realize liquor drainage function. The utility model has the effects that the drainage pump shortens well repair period, and reduces oil layer pollution, labor strength and drainage cost.
Description
One, technical field:
The utility model relates to a kind of oil field oil water row device for picking, specifically is a kind of oil well tubing string positive displacement pump.
Two, background technique:
At present, existing positive displacement pump divides two kinds in the oil field operation: a kind of is to be lowered to sucker rod to carry out pump pump drainage liquid in flow string; A kind of is the pumping equipment that utilizes waterpower and electric energy to drive.Existing pump drainage technique normally is lowered to sucker rod or adopts waterpower, electric drive, and the pump comb post that is lowered to all is unidirectional, two-way sealing, lower tubular column UNICOM not mutually on the pump barrel.Conventional pump arranging device uses at the scene, need be lowered to separately, can not realization operate with oil tube transmission perforation, acidifying, test step integrated pipe column.
Three, summary of the invention:
The purpose of this utility model is exactly the defective that exists at prior art, provide on a kind of realization pump barrel lower tubular column unimpeded, can disposablely finish acidifying discharge opeing, test discharge opeing, once finish the oil well tubing string positive displacement pump of the discharge opeing operation behind oil tube transmission perforation and the perforation.
Its technological scheme is: the utility model comprises connecting rod, plunger piston assembly, traveling valve assembly, pump barrel assembly, standing valve assembly, lock tube, connecting rod is provided with tubing round thread, plunger piston assembly, pump barrel assembly and lock tube can be connected oil pipe by the tubing round thread on the connecting rod, standing valve assembly and traveling valve assembly require to throw in separately according to discharge opeing, finish the overall package of tubing string after the input, anchoring string is realized the discharge opeing function again.
Effect of the present utility model is: shortened the well workover cycle, reduced oil layer pollution, reduced labor intensity, reduced the discharge opeing cost.
Four, description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Five, embodiment:
With reference to accompanying drawing, the utility model comprises connecting rod 1, plunger piston assembly 2, traveling valve assembly 3, pump barrel assembly 4, standing valve assembly 5, lock tube 6, connecting rod 1 is provided with tubing round thread 7, plunger piston assembly 2, pump barrel assembly 4 and lock tube 6 can be connected oil pipe by the tubing round thread on the connecting rod 17, standing valve assembly 5 and traveling valve assembly 3 require to throw in separately according to discharge opeing, finish the overall package of tubing string after the input, anchoring string is realized the discharge opeing function again.
During use, connecting rod 1 is connected with oil pipe, and connecting rod 1, plunger piston assembly 2, pump barrel assembly 4 and lock tube 6 are connected on the oil pipe by the tubing round thread on the connecting rod together.After finishing operations such as perforation, pressure break, acidifying, test, drop into standing valve assembly 5 earlier, drop into traveling valve assembly 3 again, anchoring string just can spur oil pipe the fracture acidizing liquid of down-hole is extracted out.
Claims (1)
1, oil well tubing string positive displacement pump, comprise connecting rod, plunger piston assembly, traveling valve assembly, pump barrel assembly, standing valve assembly, lock tube, it is characterized in that: connecting rod is provided with tubing round thread, plunger piston assembly, pump barrel assembly and lock tube can be connected oil pipe by the tubing round thread on the connecting rod, and standing valve assembly and traveling valve assembly require to throw in separately according to discharge opeing.
