Abstract

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.

Description

technical field [0001] The invention relates to a pipeline block removing device and a blocking removing method, in particular to a crude oil pipeline coagulation pipe blocking removing device and a blocking removing method using the blocking removing device, and belongs to the technical field of crude oil transportation. Background technique [0002] During the transportation of crude oil, the temperature of the oil in the pipeline will gradually decrease. When the temperature is lower than the wax precipitation point of crude oil, the wax dissolved in the crude oil will gradually precipitate out to form solid paraffin crystals, and some of the paraffin crystals will adhere to the inner wall of the pipeline. , forming paraffin crystal centers. As the temperature continues to decrease, the paraffin crystals on the pipe wall begin to grow, forming a wax layer with uneven thickness, resulting in a gradual decrease in the inner diameter of the pipe. When the temperature of cru...
