Features: The subterranean screw pump oil production system has unique advantages in extracting high-viscosity, high-wax, high-sand, and high-gas oil from wells, as well as in operations in (inclined wells), horizontal wells, marsh areas, and offshore platforms. It boasts high pump efficiency, lower energy consumption per unit of oil production compared to conventional methods, longer inspection cycles, lower manufacturing costs, and reduced maintenance expenses. Since the breakthrough in key technologies of the system in 1998, this oil production technology has been rapidly expanding in oilfields such as Liaohe, Shengli, and Bohai in China. The book summarizes theoretical research achievements and practical application experiences related to this technology in recent years, incorporating previous theoretical findings. The content includes an overview of subterranean screw pump oil production technology and equipment; the theoretical foundation of single-screw pumps; oil production supply-demand coordination and selection design for screw pumps; reducers and coupling devices; a comprehensive analysis of factors restricting the rotational speed of screw pump rotors; subterranean screw pump oil production operation monitoring technology; protectors; subterranean cables, etc. The book focuses on the introduction of applied technology, with some content being unpublished experience methods. These methods play a significant role in guiding the design and manufacturing of critical mechanical components in the system and optimizing control during system operation. Through this book, a wide range of science and technology personnel engaged in oil production engineering, petroleum machinery design and manufacturing personnel, as well as frontline equipment installation, commissioning, management, and control personnel, can understand and master subterranean screw pump oil production technology from different perspectives. The book helps solve technical problems in practical applications and can also serve as a reference for students and teachers in relevant disciplines at colleges and universities.
