Abstract: In oilfields in the high water cut stage and with multi-set well patterns, parallel exploiting, exploitation and underground conditions have become much more complex and problems like oil well mineralisation blockage and scaling are obvious, seriously impacting the oilfield water flooding efficiency. This paper designs a positive-negative pressure pulse control system for oil well plug removal based on the principle of positive-negative pulse, implements the main equipment selection, PLC and software programming, constructs a set of plug removal control system and successfully conducts the experiment of the positive-negative pressure pulse control system for oil well plug removal.

Keywords: oil well plug removal; positive-negative pressure pulse; PLC; Kingview.
