AP25795745 – Development and study of a new valve assembly model for sucker rod pump units to improve operational performance

Objective of the project – is to obtain porous electrodes with a high specific surface area by the synthesis of titanium dioxide nanotubes (TiNT) and the carbon material (C), with further N-doping for application in vanadium flow batteries.

Relevance: Currently, as oil fields age, pump-based extraction methods are becoming increasingly important. Sucker rod pumping units are widely used; however, improving their reliability and service life remains a key challenge. Valve assembly failures are one of the main causes of equipment downtime and increased maintenance costs. Therefore, there is a need to enhance the design of pump components. This study aims to improve the efficiency and reliability of oil production systems.

Scientific supervisor: Doszhan Ergenovich Balgayev, PhD.

Expected and achieved results: As a result of the research, a new design of the sucker rod pump valve assembly was developed, demonstrating technical novelty and ease of implementation. Analytical and experimental studies confirmed the rotation of the valve element and stable seating of the ball during closure. Empirical tests allowed increasing the pump service life and maintenance interval up to 150 days or more. Sketch designs were prepared, and a pilot batch of valves was produced using a 3D printer. The obtained results provide a solid basis for commercial implementation in oil and gas enterprises.
