Abstract: The effective application of water injection wells in oilfield operations plays an important role in improving the production quality of oilfields and the actual revenue of oilfield enterprises. Aiming at the current problems of mineralisation blockage and scaling in oil production, this paper designs a positive-negative pressure pulse automatic control system for plug removal. First, it studies the main equipment for the implementation of positive-negative pulse automatic control, and then designs the technical principles, control logic and implementation methods of positive pressure pulse, negative pressure pulse, and positive-negative coupling control. Next, the control effect is verified by the automatic control experiment platform and the control parameters are optimised. Finally, the optimised control effect is verified by experiment using the control platform.
