Oil field fracturing pumping remote automatic control system

Abstract

The invention discloses a remote automatic control system of a fracturing pump skid used in an oil field. The system is used for remote automatic control of a well service pump skid and a truck-mounted skid used in the oil field; the remote automatic control system consists of a field control system which consists of Siemens S7-315 series PLCs which are taken as a core, a Siemens MP370 which is taken as a remote control human-machine interface, and Ethernet which is taken as a transmission media; the system can achieve remote control functions such as start, stop and emergency stop of an engine, gear shifting, braking, turning back to a neutral position and idle speed of a gearbox and the like, and the system can modify field running parameters in a remote manner, thus realizing bidirectional transmission between the pump skid and the human-machine interface (HMI); the Ethernet is taken for communication so that the pump skid can transmit the field data to a remote controller or a server at the speed of 100MB/S; an industrial exchanger is taken to connect the devices such as the PLC, the HMI and the like to achieve more group controls; the exchanger can convert the field data into the data formats such as a standard *.CSV format and the like, and directly transmit the data to the server for data processing.

Description

Technical field: [0001] The invention relates to the fields of engine, gearbox and signal control, in particular to a remote automatic control system for oilfield fracturing pump skids, which is mainly used for remote automatic control of pump skids and vehicle-mounted pump skids for oilfield drilling platforms. Background technique: [0002] At present, the existing oilfield fracturing pump skid control system, on the one hand, has slow transmission speed, short transmission distance, and little transmitted data, and cannot observe and monitor the on-site work in time; on the other hand, due to the large number of detection and control components, although Each fracturing pump skid has corresponding status and fault indicating instruments, but due to the high working pressure of the fracturing skid, people cannot operate near the equipment, so it must be controlled from a distance, so that the local instruments cannot be activated. To give instructions and reference to the ...
