Abstract

The invention relates to a gas content analysis device which is used for analyzing the gas content of a shale core in a well site and comprises a control module, a core processing module, a gas processing module and a gas analysis module, wherein the rock core processing module is connected with the control module and is used for processing the shale rock core; the gas treatment module is connected with the control module and used for treating gas released by the rock core and reducing the content of water vapor in the gas; the gas analysis module is connected with the control module and is used for detecting the content ratio of methane in the gas treated by the gas treatment module. According to the device, the shale core is treated to obtain the gas released by the shale core, the gas is treated, water vapor in the filtered gas is absorbed, the treated gas is detected, and high-precision methane content data in the gas is obtained.

Description

technical field [0001] The invention relates to the technical field of natural gas measurement, in particular to a gas content analysis device. Background technique [0002] For a long time, mechanism-rich shale has been considered as the source rock and sealing layer of conventional petroleum systems. However, the commercial production of shale gas has changed this perception, and in recent years, due to the emergence of shale as a valid oil and gas reservoir, it has received renewed attention. Shale gas refers to unconventional natural gas that occurs in reservoir rock series dominated by organic-rich shale. Shale gas can be generated in various stages of organic origin, and mainly exists in mudstone, high-carbon mudstone, shale and silty rock interlayers in an adsorbed or free state. my country is rich in shale gas resources, and the development of the shale gas industry has a good resource base. In 2015, the Ministry of Land and Resources released the latest survey an...
