AI Technical Summary
Existing underwater oil equipment testing devices cannot conduct high-temperature and high-pressure tests simultaneously, and cannot fully simulate the downhole environment, affecting the verification of product performance and safety performance.
An underwater high-temperature and high-pressure test device was designed, including a pressure vessel shell, a head, a temperature and pressure sensor, a heating device, and a pressurization device. The device simulates the high-temperature and high-pressure environment in wells by heating with oil and pressurizing with water injected into the pressure vessel, and uses the temperature and pressure sensor for detection and control.
It enables the simulation of high-temperature and high-pressure environments for underwater oil equipment, comprehensively tests product performance and functions, reduces testing costs, and improves safety.
