Abstract: ESP lifting and TCP under balance perforating technology in oilfield repairing completion well are relatively independent and mature technology.Both are relatively separate in previous completion method as follows:firstly doing TCP under balance perforating operation,then killing well,finally burrowing into electric submersible pump completion.The conventional repairing completion technology inevitably results in certain damage to reservoirs such as long operation time and high cost.In order to solve the contradiction,the new repairing completion technology of ESP lifting and TCP under pressure perforating joint operation is put forward.The technological measures combine the two technologies organically and cancel the intermediate link of killing well to protect reservoirs at most,reduce operation time and cost.The new repairing completion technological measures have applied successfully in well repairing operation of Weizhou oilfield with remarkable effects.
