Description
technical field [0001] The invention relates to a desorption gas measuring instrument, which is an instrument for measuring the gas content in the exploration of unconventional oil and gas resources such as coal bed gas and shale gas, which are mainly adsorbed gas. The instrument can measure the desorption process of the adsorbed gas in coalbed methane and shale gas throughout the process, and accurately calculate the key parameters such as the content of desorbed gas and desorbed methane through the changes of main components such as carbon dioxide, methane and hydrogen sulfide, which are the reserves. The calculation provides an important basis and belongs to the technical field of unconventional oil and gas experiments. Background technique [0002] As new natural gas resources, coalbed methane and shale gas are receiving more and more attention in China. Coalbed methane and shale gas are mainly stored in the adsorption state. After the pressure is released, the gas is g...
