Design and implementation of embedded design-based PCP water injection system

PCP, the pump-controlled pumping technology, can improve the efficiency of water injection system and reduce energy consumption. The PCP water injection system, which is compact in size due to embedded design, consists of a lower machine with PLC and an upper computer with configuration software installed. The lower machine collects and processes the signals from the sensors, and then uploads them to the upper computer, while the MCGS configuration software in the upper computer mainly monitors, displays and stores the on-site parameters of water injection equipment and production parameters, whose main task is to automatically adjust the operating parameters of the small pump according to the parameters to ensure the optimal operation of the system. The field data shows that this system can automatically make the injection pump work in the best efficiency section, reducing the labor intensity of staff and improving the efficiency of water injection, compared with the previous one.
