Multi-element composite high-pressure water jet cleaning device

Abstract

The invention relates to a multi-element composite high-pressure water jet cleaning device for cleaning gathering pipeline networks of oil fields. The aim of the invention is to break the limitation of the existing high-pressure water jet cleaning. The multi-element composite high-pressure water jet cleaning device comprises a diesel engine served as a power source and a high-pressure cleaning pump connected with the diesel engine by a clutch, wherein a water outlet end of the high-pressure cleaning pump is connected with a high-pressure one-way valve by a high-pressure steel pipe; the high-pressure steel pipe between the high-pressure cleaning pump and the high-pressure one-way valve penetrates through a numerical control electromagnetic heating system; an output shaft at the rear end of the diesel engine is connected with an air pump and a driving shaft of a generator by a transmission belt; an output end of the air pump is connected with a pulse control system and an air one-way valve in turn; and the air one-way valve and the high-pressure one-way valve are connected with a high-pressure quick coupling. The device adopts a mode of combining air pulsing and high-pressure water jet, so that the device has the characteristics of wide applicable range, good cleaning effect, fast cleaning speed, safety, reliability, low cost and environmental friendliness.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a multi-component composite high-pressure water jet cleaning device used for cleaning pipelines in oil field gathering and transportation pipeline networks. Background technique [0002] With the continuous deepening of oil field development, oil-water well pipes and underground gathering and transportation pipelines blocked by severe scaling can reach thousands of kilometers every year. Chemical raw materials, and the operation time is long, which will cause corrosion to the pipeline matrix. In addition, the waste water discharge is difficult to meet the standard, and it is not easy to handle, causing environmental pollution. In order to solve the pollution problem, the high-pressure water jet physical cleaning technology is being gradually promoted, and has become the leading technology for oil field cleaning. However, the commonly used high-pressure water jet cleaning equipment is general...

Problems solved by technology

However, the commonly used high-pressure water jet cleaning equipment is generally only suitable for working conditions above 0°C, and 70% of oil and water wells in oil fields are still operating in winter. When the winter temperature is lower than -5°C, high-pressure water jet The cleaning equipment cannot even work normally without the support of heat energy; in addition, the commonly used high-pressure water jet physical cleaning technology adopts the method of heating first and then pressurizing, which leads to accelerated aging of the seals of the high-pressure pump, making the water jet pressure and jet velocity unstable. Unable to completely remove slime, colloid, wax scale and other dirt in the oil pipe
