Description

technical field

[0001] The invention belongs to the technical field of oil and gas exploration and development, and in particular relates to a shale gas content testing device. Background technique

[0002] The experimental techniques for shale gas content analysis mainly include direct test method, desorption test method, and isothermal adsorption simulation method. Among them, the desorption test method is the most commonly used experimental method for shale gas content measurement. However, at present, there is no specific method and technology industry standard at home and abroad. It mainly refers to the measurement method proposed in the coalbed methane industry, and then applies the test method and parameters to the shale gas content test after modifying the experimental method and parameters in combination with the characteristics of shale. At the same time, the corresponding test instruments are also developed by various research units according to the needs, and th...
