Centralized control system of fracturing well site equipment

Abstract

The invention discloses a centralized control system for fracturing well site equipment. The centralized control system comprises a fracturing well site equipment module, a wireless communication module, a centralized control module and an automatic control module; the centralized control module performs remote centralized control on the fracturing well site equipment through the wireless communication module; and the automatic control module achieves automatic construction of well site operation by designing an automatic operation table and issuing the automatic operation table to all PLCs of the well site equipment. According to the centralized control system for the fracturing well site equipment, required constant pressure control, constant liquid level control and the like are realized by adopting a classic PID control algorithm, and automatic sand conveying control, automatic liquid supply control, automatic displacement distribution and automatic mixing and liquid supplementing control are realized by designing linkage logic of the equipment; and through remote centralized control of the equipment, the problems of personnel dispersion, redundancy and the like are effectively solved, the controllability, the stability, the operation simplicity and the timeliness of the equipment are improved, the production operation cost is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of fracturing in oil and gas fields, in particular to a centralized control system for fracturing well site equipment. Background technique [0002] In the field of fracturing in oil and gas fields, many wellsite equipment are involved, such as generator sets, fracturing pumps, air compressor units for mud treatment systems, top drives, sand tanks, water tanks, and sand mixing skids. With the development of drilling technology, wellsite equipment is constantly being upgraded, and its types are increasing. During the drilling process, in order to ensure the normal operation of each fracturing well site equipment, the operation of the well site equipment is very cumbersome; some equipment cannot be corrected according to the fault information due to the inevitable failure of some equipment during use. To predict and evaluate the cause of the failure, it is necessary to visit the site to shut down the equipmen...

Problems solved by technology

During the drilling process, in order to ensure the normal operation of each fracturing well site equipment, the operation of the well site equipment is very cumbersome; some equipment cannot be corrected according to the fault information due to the inevitable failure of some equipment during use. To predict and evaluate the cause of the failure, it is necessary to visit the site to shut down the equipment and disassemble it for inspection. It is impossible to quickly and accurately determine the cause of the failure, which affects the construction efficiency

In the current domestic shale gas fracturing industry, the control of equipment and process parameters is limited to local control, and communication often relies on intercom equipment such as walkie-talkies. Information asymmetry; each device is independent and scattered, requiring more personnel to be assigned, and the personnel are scattered, the command response is poor, and the operation between each device is cumbersome
