Breaking News: China Petroleum & Natural Gas Corporation Seeks Patent for Innovative "Piston-Type Internal Thread Screw Pump"

 

Financial World, January 5, 2024 - In the latest development, China Petroleum & Natural Gas Corporation has filed a patent application titled "Piston-Type Internal Thread Screw Pump" with the National Intellectual Property Administration, under publication number CN117345616A. The application, submitted in June 2022, brings forth a groundbreaking solution in the field of oil production engineering.

 

The patent abstract outlines the key features of this pioneering invention. The piston-type internal thread screw pump incorporates a piston-based screw pump cylinder, enhancing its performance and efficiency. Specifically, the top of the screw pump piston rotor is seamlessly integrated with a power section, allowing for optimized power transmission. Equally noteworthy is the presence of a valve ball at the bottom of the piston-type screw pump cylinder, ensuring smooth crude oil passage. The design is further enhanced by the inclusion of a centrifugal column within the screw pump piston rotor.

 

This groundbreaking innovation offers a host of advantages over traditional screw pumps. With its accelerated lifting capacity, high displacement, and increased lift, the piston-type internal thread screw pump generates substantial impact kinetic energy. Its key benefit lies in effectively mitigating sand and paraffin blockages in oil wells, resulting in boosted oil well production, extended production cycles, reduced operational frequency, and lowered cost per ton of oil. Furthermore, it showcases exceptional compatibility with heavy and extra heavy crude oil wells, as well as SAGD horizontal wells, significantly elevating the quality and efficiency of oilfield enterprises.

 

Stay tuned for further updates on this remarkable technological breakthrough as it progresses towards implementation in the oil production industry.
