Integral apparatus for cleaning work

Abstract

An integral apparatus for cleaning work belongs to the technical field of petrochemical equipment and can effectively solve a problem of well field environment pollution due to water containing oil dirt during the well repairing work. An outlet of a solid-liquid separator communicates with an inlet of an oil-water separator; the other end of a high-pressure hot water joint communicates with a first nozzle of an oil pipe inner wall cleaner via a pipeline, or the other end of the high-pressure hot water joint communicates with an oil removing and cleaning mechanism; and an inlet of the solid-liquid separator communicates with a well mouth and the oil removing and cleaning mechanism. Cleaning effect for an oil pumping rod or an oil pipe can be improved, so the oil pumping rod or the oil pipecan reach a work standard after being cleaned; the water containing oil dirt can be recycled after being processed, so transportation time and cost can be reduced; environment protection requirementsfor onsite work can be met; cleaning work can be achieved; and a problem of environmental pollution of well repairing work can be solved, so the integral apparatus for cleaning work is an environment-protective innovation product being favorable for the nation and the people.

Description

technical field [0001] The invention belongs to the technical field of petrochemical equipment, in particular to an integrated cleaning device. Background technique [0002] Oil well workover operations in oil fields are often accompanied by environmental protection problems caused by oily sewage generated during the cleaning of the wellhead pressure relief valve, wellhead pressure relief valve overflow, and the cleaning of the inner and outer walls of the sucker rod and tubing. However, the existing cleaning equipment The treatment of oily sewage and the cleaning effect on the inner and outer walls of sucker rods and oil pipes are not satisfactory, and the environmental pollution problems caused by workover operations have not been fundamentally solved. Contents of the invention [0003] In view of the above-mentioned technical problems, the present invention provides a method for cleaning the inner and outer walls of sucker rods and oil pipes to meet the clean and enviro...
