Abstract
Rod borehole pumping units (RBPU) are designed to lift reservoir fluid from the well to the day surface. Over 70% of the existing well stock is equipped with deep well pumps. With their help, about 30% of oil is extracted in the country. Currently, RBPU is usually used on wells with a flow rate of up to 30...40 m3 of liquid per day, less often up to 50 m3 at average suspension depths of 1000...1500 m. In shallow wells, the installation provides liquid lift up to 200 m3/day. In some cases, a pump suspension can be used to a depth of up to 3000 m. This article presents technological and technical techniques to reduce the harmful effect of free gas on the operation of the deep pump. The practical significance of the study lies in the fact that the results of the work performed on the topic “Review of methods for reducing the influence of free gas on the operation of a deep well pump of a sucker rod pumping unit” can be used as a basis for theoretical research, analytical and design activities of authors studying this area.The second aspect of the practical significance of this study is the possibility of using the research results within the framework of the topic “Review of methods for reducing the influence of free gas on the operation of a deep pump of a sucker rod pumping unit” in order to develop the mechanism for the functioning of protective devices of pumps from the harmful influence of gas.
