Description

technical field [0001] The invention relates to the technical field of intelligent control, in particular to an intelligent monitoring system for oilfield water injection. Background technique [0002] Oilfield water injection mostly adopts single-pipe multi-branch process. With the extension of water injection time and the difference in water absorption capacity of single wells, it is difficult to control the water injection volume of a single well, and the water injection volume of a single well will fluctuate with the fluctuation of water injection pressure, resulting in The phenomenon of over-injection and under-injection occurs, making it difficult to achieve smooth water injection. In order to achieve fine and steady flow water injection and reduce the difficulty of operation by staff, researchers at home and abroad have begun to develop the remote monitoring technology of steady flow water injection. Carry out online automatic tracking, monitoring and regulation, acc...

Problems solved by technology

At present, there are some remote monitoring and monitoring systems for oil and water wells in the prior art. However, there are still complex networking, complex wellhead devices, and the need for power supply. As a result, the wellhead devices often fail and cannot realize the automatic inspection of the collected data. The defects and insufficiencies of the remote dispensing of the water injection volume cannot achieve smooth water injection, quantitative water injection and accurate water injection
