Description

Technical Field

[0002] Water injection development refers to the process of injecting water into the oil reservoir through special injection wells during oil field development to maintain or restore the reservoir pressure, giving the oil reservoir a strong driving force to increase the oil reservoir's mining / oil production rate and oil field recovery rate.

[0003] The traditional water injection development process cannot remotely control the water flow rate, which will cause the formation of biofilm / bacterial flora in the pipe body, causing water injection / water pollution, making work difficult / affecting normal production operations, and inaccurate pressure detection. In addition, the method of relying on the close proximity between the pipe sleeves to prevent water leakage in the connecting sleeves for conveying water is not advisable. It is difficult to make the pipe sleeve connection airtight without external barriers. If welding is used, the project volume is large and the investment cost is high. Therefore, a pressure monitoring device in the water injection development process is needed to improve the above problems. Utility Model Content
