Full-automatic intelligent control well flushing vehicle and control method thereof

Abstract

The invention discloses a full-automatic control well flushing vehicle and a control method thereof, and belongs to the technical field of special vehicles for oilfields. The full-automatic intelligent control well flushing vehicle integrates equipment real-time operation data monitoring and cloud data real-time transmission, can safely and efficiently complete well flushing operation of an oilfield water injection well, by collecting data information fed back by a pressure sensor, a temperature sensor, a flowmeter, a measuring instrument for suspended matter in water, a measuring instrument for oil in water, a chassis engine and the like, the real-time working states of a three-cylinder plunger pump, an automobile chassis engine and an operation water quality effect are monitored, the full-automatic intelligent control well flushing vehicle solves the technical problems that a traditional water injection well flushing vehicle cannot effectively maintain the high-pressure safe operation condition, water quality parameters of each stage of well flushing are unknown, construction operation data is missing, operation data cannot be remotely transmitted, downloaded and analyzed, reasonanalysis cannot be effectively performed when an abnormal condition occurs during operation, the overall machine is simple in structure, and by utilization of cloud technology, and the degree of automation is high.

Description

technical field [0001] The invention relates to the technical field of special vehicles for oil fields, in particular to a fully automatic intelligently controlled well washing vehicle and a control method thereof. Background technique [0002] The well flushing process of conventional water injection wells in oilfields is to release the pressure in the water injection wells to low pressure for well flushing, and re-establish a higher pressure in the wells after the well flushing is completed to meet the production needs of surrounding oil wells. With the development of oilfield water injection technology, The flushing pressure of water injection wells is continuously increasing, and the pressure before flushing may be maintained for high-pressure flushing to solve the problem of reduced production of surrounding oil wells caused by pressure relief during well flushing. This high-pressure well flushing method has high requirements on the pressure, flow rate, operating parame...
