Real Time In-situ Detection System Research for Methane in Offshore Shallow Gas based on Thin Film Interface
In order to get ridded of the non real-time detection methods of artificial site sampled and laboratory instrument analyzed in the field of methane detection in the offshore shallow gas,real-time in-situ detection system for methane in offshore shallow gas was designed by the film interface.The methane in the offshore shallow gas through the gas-liquid separation membrane of polymer permeation into the system internal detection probe,analog infrared micro gas sensor sensed the methane concentration and the corresponded output value,data acquisition and communication node fitted into standard gas concentration.Based on the experimental data compared with the traditional detection method,and further analyzed the causes of error produced by the case experiment.The application results show that the system can achieve a single borehole layout,long-term on-line in-situ on-line detection,and improve the detection efficiency and the timeliness of the detection data.
