The invention relates to a
pipe plug removal device and a plug removal method, in particular to a
crude oil coagulated
pipe plug removal device and a plug removal method with the plug removal device. The problems that existing
pipe coagulated pipe plug removal is high in cost, and environmental
pollution is easily caused are solved. The
crude oil coagulated pipe plug removal device is characterized in that a liquid inlet pipe, a liquid outlet pipe and a stirrer transmission shaft are installed in a sleeve in a sleeved mode, the liquid inlet pipe is connected with a
liquid injection pump, the stirrer transmission shaft is connected with a motor, the liquid outlet pipe is connected with a liquid
infusion pump, and the stirrer transmission shaft is connected with a stirring head of a stirrer. The plug removal method includes the steps of judging the position of a coagulated pipe section, determining an available opening of the pipe, inserting the sleeve into the available opening, and enabling the stirring head to be in contact with coagulated
crude oil; starting the motor to drive the transmission shaft to drive the stirring head to
crash the coagulated crude oil; starting the
liquid injection pump to pump plug removal liquid into the coagulated crude oil section; starting the liquid
infusion pump to pump out mixing liquid; when plug removal is finished, shutting down the
liquid injection pump and the motor, then shutting down the liquid
infusion pump, pulling out the sleeve, recovering the original appearance of the pipe, and finishing plug removal. The device and method are used for crude oil coagulated pipe plug removal.
