The reliability of the underground equipment of a well sucker rod pump installation will be improved by the use of a new sand filter design, the principle of which is based on the use of centrifugal force of a moving reservoir fluid. To determine the subtlety of cleaning the reservoir fluid from mechanical particles, it should be considered that the fluid velocity is the same as the particle velocity. To do this, we use the universal expression by analogy to our case for the stream function. To develop a specific filter (determination of structural dimensions) taking into account the well conditions, nomograms are developed taking into account all technical and technological conditions. The main advantage of the developed sand filter over other designs is the ability to pass formation fluid even when the cavity for collecting sand and the space between the filter housing and the pipe with radial channels are filled. The presence of the latter also does not affect the performance of the sucker rod pump, in the absence of jamming of the plunger in the cylinder.
