Chemical equipment has developed greatly in the past ten years. Praise for China's prosperity and strength in the prosperous age. It will be more lively and exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions. Everyone pays attention to safety and knows how to respond to emergencies. * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Recently, the thermal recovery balanced injection and production integrated control valve developed by CNOOC Research Institute was successfully tested on the LD5-2 North Oilfield Phase I platform, and the gas injection effect was good. The successful development of the balanced injection and production integrated control valve has filled the gap in the field of key tools for offshore heavy oil thermal recovery, achieved efficient and balanced injection and production downhole, and provided a solid guarantee for the large-scale development of offshore heavy oil. The balanced injection and production integrated control valve for thermal recovery passed 8 rounds of alternating hot and cold high-temperature tests, normal temperature and 350°C high-temperature pressure tests, and finally achieved uniform steam injection in the horizontal section. During the production stage, the flow friction was more than doubled compared to conventional tools, fully verifying the functional stability and reliability of the tool.
