Abstract
The article discusses the influence of sand and mechanical impurities on the operation of borehole pumps (USA) during oil production. Sand coming out of the reservoir leads to the destruction of pump parts, piston jamming, damage to threaded connections and rapid wear of pipes, which leads to a shortened repair period. Various methods are proposed to combat these problems, such as the installation of sand anchors, the use of filters and tubular rods. It also provides for the use of additional equipment, including gas sandblasting anchors (PG), a tubular zoom camera (КТО) and an auto connection, which will effectively reduce the impact of sand and mechanical particles on pumping equipment. The combined use of these devices helps to increase the service life of pumps, reduce the likelihood of jamming and wear of pairs of pistons and valves, and simplify the maintenance process. The results of the analysis of the work of 107 wells in the fields of the Western region of the Republic of Kazakhstan confirm the effectiveness of the proposed solutions in improving the operational characteristics of rod pumping units.
