Comprehensive well site measurement and control cabinet

Abstract

The invention relates to a comprehensive well site measurement and control cabinet. As an oil well is located in a wild and desolate site with a harsh environment, objective factors form a severe test on a network communication system of an oil field. The invention aims at providing the comprehensive well site measurement and control cabinet. A communication unit and a measurement and control unit process signals detected by devices such as an oil field sensor and a motor, and the signals are finally transmitted to a man-machine interaction interface of an upper computer in a TCP/IP, Modbus or other form; a video monitoring and communication unit is provided with a McWill MEM136 communication module, the module has a flexible network architecture and is a communication mode mainly promoted by the measurement and control cabinet; the measurement and control cabinet can be compatible with various communication protocols according to actual conditions; and the measurement and control unit is provided with RTU and PLC control modules and supports Modbus-RTU and TCP/IP protocols. The comprehensive well site measurement and control cabinet can be compatible with various communication protocols, invasion of natural disasters such as thunder and lightning, rain and snow, sand wind and the like can be resisted, and the RTU/PLC is in a relatively-stable operation environment; the measurement and control cabinet can resist theft, damage and explosion; and the inner space is reasonably arranged, and late maintenance and expansion are facilitated.

Description

technical field [0001] The invention relates to the field of crude oil exploitation, in particular to a well site comprehensive measurement and control cabinet. Background technique [0002] At present, in the field of domestic crude oil exploitation, RTU or PLC is generally used as industrial control components to measure and control various parameters of oil wells. In actual use, RTU or PLC is usually placed in oil well measurement and control cabinets. From the perspective of application, since the oil wells are located in the wilderness with harsh environment, and most of them are scattered, these objective factors are a severe test for the network communication system of the entire oil field. From the well site to the booster station, and then from the booster station to the operation area, the data bandwidth required for transmission between each level varies greatly, and will vary greatly according to the actual situation on site. Different equipment, but most of the...

[0002] At present, in the field of domestic crude oil exploitation, RTU or PLC is generally used as industrial control components to measure and control various parameters of oil wells. In actual use, RTU or PLC is usually placed in oil well measurement and control cabinets. From the perspective of application, since the oil wells are located in the wilderness with harsh environment, and most of them are scattered, these objective factors are a severe test for the network communication system of the entire oil field. From the well site to the booster station, and then from the booster station to the operation area, the data bandwidth required for transmission between each level varies greatly, and will vary greatly according to the actual situation on site. Different equipment, but most of the existing common measurement and control cabinets use the same type of equipment, which causes a great burden on the upper network, causing the network to often freeze or even disconnect, seriously affecting the communication quality
