Gel plug packing well control method

The invention discloses a gel plug packing well control method. The well control method includes the following steps that S1, a gel plug is built in a wellbore when spillage together with complicated wellbore conditions appear; S2, throttling circulating exhaust is performed on packed upper portion of the wellbore; S3, preparatory work for boring stopping and leaking stoppage is performed in safe operation time provided by wellbore packing; S4, the gel plug is broken to remove the wellbore packing, and leaking stoppage operation is performed by the adoption of an extrusion method; S5, weighted drilling fluid is used for throttling well killing. The well control method has the advantages that due to wellbore packing through the gel plug and removal of wellbore packing through gel breaking, a brand new choice is provided for processing the complicated wellbore conditions; the gel plug blocks an oil-gas shifting-up channel, in this way, overflow is effectively controlled to be located in the bottom hole, the safe operation time is provided for leaking stoppage and well killing, and safety risks of well control are reduced; the technical thought is novel, the technical scheme is reliable, and the well control method is beneficial for forming a practical engineering technology.
