Method for adjusting depth of oil well pump

Abstract

The invention relates to a method for adjusting the depth of an oil well pump, and can solve the problems of long operation time, high cost and low operation efficiency in the prior art caused by thefact that in order to adjust the length of an oil pipe on a pump, a sucker rod and a plunger in the oil pipe are both pulled out. The method for adjusting the depth of the oil well pump comprises thesteps that a sucker rod and a plunger are lifted upwards, the upper part of the sucker rod is detached, and a fixing device is connected to the upper end of the remaining part of the sucker rod; the remaining part of the sucker rod and the plunger are lowered into an oil pipe through a feeding oil rod, and after the fixing device and the oil pipe are relatively fixed, the feeding oil rod is takenout; the oil pipe is spliced continuously or removed so as to adjust the depth of a pump barrel in an oil well; the fixing device, the sucker rod connected with the fixing device and the plunger are lifted up by a taking-out oil rod, and the fixing device is detached; and a sucker rod with a suitable length is connected to the upper end of the remaining part of the sucker rod and the plunger, andthe plunger is lowered into the pump barrel.

Description

technical field [0001] The invention relates to a method for adjusting the pump depth of an oil well pump. Background technique [0002] After the self-spraying period of onshore oilfields, technicians will put in tube pumps in the oil fields to pump downhole crude oil to the ground. The tube pumps include pump barrels, suction valves, discharge valves and plungers. When in use, first connect the pump barrel to the bottom of the tubing, use the tubing to lower the pump barrel into the well to a certain depth, then connect the sucker rod to the plunger, lower the plunger into the pump barrel, and install the suction valve on the pump In the barrel, the crude oil can enter the pump barrel in one direction, and the discharge valve is fixed on the plunger, so that the crude oil entering the pump barrel can be discharged into the oil pipe above the plunger, and finally discharged to the ground. [0003] In the prior art, when it is necessary to adjust the pump depth due to poor ...
