Background
The ternary composite oil displacement well has the problems of complex working conditions, viscous well fluid, high scaling speed, large scaling amount, serious abrasion of a rod pipe, short pump detection period and the like. The soft plunger pump reduces the abrasion of the plunger pump by adjusting the different stress of the plunger body in the operation process of the up stroke and the down stroke, thereby achieving the purpose of prolonging the pump detection period. In the prior patent CN108980018A, a flexible pump barrel plunger pump with a flexible pump barrel and an elastic sealing ring is adopted, so that the sealing ring expands and deforms under the action of liquid pressure during the upstroke movement, so that the plunger and the pump barrel are completely attached to complete the liquid suction process; in the process of the down stroke movement, the liquid pressure is lost, the plunger and the pump barrel are in a clearance state, the down resistance of the plunger is reduced, and the abrasion degree of the rod pipe is reduced. The technology for detecting the pump without moving the tubular column of the three-element composite drive breather pump has the advantages that the fishing tool is added, so that the oil pipe does not need to be lifted in the operation process of detecting the pump by the flexible plunger pump, the upper part of the fishing tool is in plug-in connection with the lower part of the fishing tool, the rapid operation is realized, and the purpose of simplifying the pump detection process is achieved.
