Problems solved by technology

[0005] For this reason, the present invention provides an intelligent oilfield drilling mud gas circulation and agitation energy-saving system, which aims to solve the traditional oilfield drilling mud gas circulation and agitation energy-saving system, which requires two people to switch the butterfly valve, and can only be manually operated by hand. The circulation and stirring of the mud can only be seen by human eyes, the accuracy is not high, and the air intake in the mud cannot be measured

Abstract

The invention discloses an intelligent oil field drilling mud gas circulation stirring energy-saving system, and particularly relates to the technical field of mud gas circulation stirring. The intelligent oil field drilling mud gas circulation stirring energy-saving system comprises a plurality of mud tanks, stirring assemblies are arranged in the mud tanks, branch pipes are connected to the exteriors of the mud tanks, the multiple branch pipes are connected with the same main gas channel, branch electric valves are installed outside the branch pipes, a main channel draught fan is connected to one end of the main gas channel, and a first pressure transmitter and a second pressure transmitter are installed outside the main gas channel. The intelligent oil field drilling mud gas circulation stirring energy-saving system is remotely controlled by an intelligent terminal, and all pipeline valves achieve action of an electric actuator; and meanwhile, the working dynamic state of the stirring system can be monitored in real time, gas flow and pressure distribution balance can be achieved, the gas supply pressure of a main pipeline can be monitored in real time, an alarm is given in time when the pressure is insufficient, and a standby fan is prompted and dispatched, so that the system is in the optimal energy-saving state.

Description

technical field [0001] The invention relates to the technical field of mud gas circulation and agitation, in particular to an intelligent energy-saving system for oil field drilling mud gas circulation and agitation. Background technique [0002] An oil and gas field is the sum of oil and gas reservoirs in the same oil and gas production area under the control of a single geological structure factor. An oil and gas field may have one or more oil and gas reservoirs. In the same area, it is called an oil field mainly composed of oil reservoirs, and a gas field is called mainly a gas reservoir. , and the use of mechanical equipment or manpower to drill the stratum into holes from the ground is called drilling. It usually refers to the project of drilling boreholes and large-diameter water supply wells for the exploration or development of liquid and gaseous minerals such as oil and natural gas. Drilling plays an important role in the national economy. The application in constru...
