Abstract
One of the most promising means of lifting oil is the installation of a downhole screw pump with a drive that rotates the rod column by rotating the plunger. Screw pumps are capable of producing high viscosity oil, characterized by a high sand content. The use of screw pumps reduces capital and operating costs by 25-95% compared to other types of mechs. production. Efficiency increases by 40-80% and transportation costs are reduced, as the screw pumping system has a compact design and is easily mounted on the well. The structural parts of screw pumps made of elastomers are fundamental factors in determining the service life and performance of the pump. Studies of changes in swelling and hardness of various series of elastomers within 96 hours revealed the most suitable commercial elastomer of a screw pump for the oil fields of Kumkol, Aryskum, Maybulak.
