Exploring on the measurement methods of shale gas content

Shale gas content is a key parameter to calculate shale gas in situ, it has an important significance to the evaluation of shale gas content and the prediction of resource reserves. Currently, the methods of determination shale gas content mainly include desorption method, isothermal adsorption method and the logging interpretation method. The manual measuring equipment used in shale gas content measurement is based on the principle of drainage method. This paper mainly introduce the methods of measuring the shale gas content, and focus on the discussion of the basic principle of the determination of gas content in shale by desorption method. At the same time, analyzed and compared with the existing domestic shale gas content measurement device, in the era of industrial automation, the automatic measurement of shale gas content is not only a trend of the development of shale gas content measurement method, but also improve the efficiency and precision of the shale gas content measurement, it helps to improve the accuracy of shale gas resource assessment, and obtain an unattended shale gas metering system.
