Description

technical field [0001] The invention relates to the technical field of oil well tubing cleaning, in particular to an efficient, sealed, energy-saving, environment-friendly cleaning vehicle and a cleaning method for oil well tubing. Background technique [0002] During the oil well operation, the oil well tubing must be cleaned on site to remove the crude oil dirt such as wax deposits and oil stains on the surface. The existing cleaning method is to spray hot water with a certain pressure onto the surface of the oil rod or oil pipe to be cleaned through the pipeline and the nozzle to wash off the pollutants such as wax deposits and oil dirt. The defect of this technology is: the dirt generated by washing Oil and sewage flow on the ground, causing environmental pollution at the well site. [0003] Prior to the filing date of the present invention, the applicant had used steam to flush the oil well tubing. However, during the operation and use in the past two years, the field ...

The existing cleaning method is to spray hot water with a certain pressure onto the surface of the oil rod or oil pipe to be cleaned through the pipeline and the nozzle to wash off the pollutants such as wax deposits and oil dirt. The defect of this technology is: the dirt generated by washing Oil and sewage flow on the ground, causing environmental pollution at the well site

[0003] Prior to the filing date of the present invention, the applicant had used steam to flush the oil well tubing. However, during the operation and use in the past two years, the field operation staff found that it had some defects: for example, the degree of automation is not high, especially for The monitoring of the water supply source, the recovery tank, and the temperature in the burner is not accurate enough, resulting in a relatively small amount of steam generated during use, and the energy is not fully utilized. At the same time, the sewage generated during the cleaning process of the oil well tubing cannot be recycled. use, resulting in wastage of water
