Abstract
Insufficient attention has been paid to the issues of repair and increase of the service life of plunger borehole pumps used in the oil production industry. The oil company Bashneft aims to increase the life and the IRP of borehole pumps. For this purpose, a lot of work has been done to analyze downhole equipment failures across the entire stock of oil wells equipped with sucker rod pumps. To repair the plunger pair of sucker rod pumps, all the documents (a technical task and technical conditions for repairs) were developed and the technological process was prepared. For the fields NGDU Ufaneft and NGDU Krasnokholmneft, the best results were achieved by pumps with a landing group (0.06–0.11), and for NGDU Ishimbayneft-pumps with a landing group (0.03–0.06). When repairing a pump, one can choose a landing group (plunger-cylinder), which will increase the service life of a sucker rod pump that has previously worked out its service life.
