Abstract:  This paper presented a high-performance digital signal controller-based constant oilfield injection system, and gave the control system hardware structure and flow chart of measurement and control system. The results show that this control system has a strong environmental adaptability and good system properties, it can smooth control water pressure and water injection. It can improve the efficiency of water injection pump and reduce system energy consumption, not only save a lot of money, improve the hydraulic conditions of the pipe network, but also enhance the oil production rate, and it has broad application prospects.
