This is just a starting point – more participation will make things even more lively. Haichuan becomes better with you all; we welcome everyone to engage more in discussions on this forum. Happy May Day! A safe and secure Red May ********************************************* On April 27, 2023, reporters learned from CNOOC Offshore Services Co., Ltd. that China’s first set of downhole safety valve testing equipment at the international leading level was put into use in Tianjin. This equipment resolved the challenges related to testing the stability of domestically developed downhole safety valves, marking a new breakthrough in the industrial development of such valves for high-temperature and high-pressure environments in China’s offshore oil industry.

The downhole safety valve is an essential downhole tool for ensuring the safe operation of oil wells; it can immediately shut off the flow of fluid in the well in the event of serious abnormalities such as fires or natural disasters in oil fields, and is regarded as the \"safety guardian\" for offshore oil well operations. The test equipment developed this time enables comprehensive functional testing and performance evaluation of domestically produced downhole safety valves. The testing temperature can range from -40°C to 350°C, the testing pressure can reach 280 MPa, and the axial loading force in both directions can reach 500 tons ； At the same time, it possesses the capabilities to detect nitrogen leaks, liquid leaks, and zero bubbles in seals. It is the first time in China that a set of experimental equipment has such comprehensive functional capabilities, and many of its technical specifications are at the international leading level. This will be of great significance in promoting deep-water and deep-reservoir oil and gas exploration and development, as well as ensuring an increase in oil and gas reserves and production.
