Problems solved by technology

However, when the crude oil is pumped to the wellhead, since the surface temperature is much lower than the temperature in the well, the temperature of the crude oil will gradually drop, and its viscosity will increase as the temperature drops, and the wax, asphaltenes and colloids in the crude oil will be deposited on the pipeline wall , so that the transportation resistance of crude oil increases and the output decreases
Under the action of adsorption force, the wax crystals adhere to the inner wall of the pipeline and deposit continuously. In severe cases, it may even cause a pipe condensation accident, which poses a great safety hazard to pipeline transportation.

Description

technical field [0001] The invention relates to the field of oil well pumping equipment, in particular to a viscosity-reducing treatment tank for oil well pumping. Background technique [0002] In the process of mechanical oil recovery, crude oil is pumped from the high temperature downhole through the pumping unit to the ground and transported to the oil gathering station. Most of the oil quality of crude oil is heavy oil and extra heavy oil, which has many heavy components and high viscosity, and the viscosity decreases at high temperature. However, when the crude oil is pumped to the wellhead, since the surface temperature is much lower than the temperature in the well, the temperature of the crude oil will gradually drop, and its viscosity will increase as the temperature drops, and the wax, asphaltenes and colloids in the crude oil will be deposited on the pipeline wall , so that the transportation resistance of crude oil increases and the output decreases. Under the ...
