[0025] As Figures 1-3 ​As shown, the multi-working-condition gas monitoring equipment of the smart oil field in the embodiment includes a conveying pipeline 1 and a wellhead pipeline 2, the conveying pipeline 1 and the wellhead pipeline 2 are assembled by flange connection, the upper end of the conveying pipeline 1 is fixedly installed with a hot-wire type sensor 3, one end of the conveying pipeline 1 adjacent to the wellhead pipeline 2 is fixedly installed with a flange seat 4, an integrated sensor group 5 is installed in the flange seat 4 through a clamping groove, a curved wind deflector 6 is rotationally connected in the connection part of the conveying pipeline 1 and the wellhead pipeline 2, a driving motor 8 is fixedly installed on the outer side wall of the conveying pipeline 1 at a position corresponding to the curved wind deflector 6, and the transmission output end of the driving motor 8 is fixedly connected with the curved wind deflector 6. The driving motor 8 can drive the curved wind deflector 6 to rotate.

[0026] The embodiment of the present application provides the multi-working-condition gas monitoring equipment of the smart oil field by adopting the curved wind deflector 6 which can be adjusted in rotation to guide and direct the flowing gas with a large content of coal dust impurity particles, so as to avoid damage or pollution of the sensor group caused by a large amount of coal dust particles, and ensure the service life of the sensor. The problem that the oil field wellhead sensor lacks adaptive protection adjustment mechanism in actual application in the prior art, when the gas discharged from the oil field wellhead contains a large amount of coal dust impurities, the gas particles are easy to cause serious pollution to the detection end of the sensor, thereby affecting the monitoring accuracy and service life of the sensor is solved. The general idea for solving the above problem is that: the hot-wire type sensor 3 is arranged to detect the gas flow in the oil field during the mining process, and the electrochemical sensor is used to detect the content of the gas, and the air quality sensor is used to detect the content of the coal dust impurity particles in the gas, so that the detection equipment of the smart oil field can monitor the real-time condition of the oil field wellhead. When the content of the coal dust impurity particles in the air is large, the driving motor 8 can drive the curved wind deflector 6 to guide and direct the flowing gas, thereby reducing the damage or pollution of the integrated sensor group 5 caused by the coal dust impurity particles in the air, and ensuring the monitoring accuracy and service life of the sensor.

[0027] As shown in Figure 1 and Figure 2 , the hot-wire type sensor 3 is a hot-wire type wind speed sensor, and the detection end thereof is located in the conveying pipeline 1.

[0028] As an implementation manner, the hot-wire type wind speed sensor can monitor the gas flow rate in the conveying pipeline 1 in real time, and can transmit the detection data to the control unit 9 in the form of wireless or wired electrical signals.
