Embodiment Construction
[0026] The main realization principles and specific implementation methods of the technical solutions of the present invention will be described in detail below with reference to the accompanying drawings. The method provided by the present invention adopts the principle of electrochemical method to detect mud gas downhole, and an electrochemical detection chamber is designed. The working principle of the device is as follows: figure 1 shown. It mainly includes: a water pump to ensure that the liquid in the electrochemical detection room keeps flowing; the electrochemical detection room (1) mainly consists of a two-layer filter membrane structure and a three-electrode electrochemical test system (working electrode WE, contrast electrode CE, reference electrode RE) for filtering gas and performing catalytic reactions; signal processing and transmitting devices for amplification and wireless transmission of electrical signals.
[0027] Please refer to figure 1, its working pri...
