Abstract

The invention relates to a gas content analysis device, which is used to analyze the gas content of shale cores in well sites. The gas content analysis device includes: a control module, a core processing module, a gas processing module and a gas analysis module; a core processing module and a control module connection, the core processing module is used to process the shale core; the gas processing module is connected to the control module, and the gas processing module is used to process the gas released from the core to reduce the content of water vapor in the gas; the gas analysis module is connected to the control module, The gas analysis module is used to detect the proportion of methane content in the gas processed by the gas processing module. The invention processes the shale core to obtain the gas released from the shale core, processes the gas, absorbs and filters the water vapor in the gas, and detects the processed gas to obtain high-precision Methane content data.

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...
