Shale adsorbed gas content analysis system

Abstract

The invention discloses a shale adsorbed gas content analysis system. According to the shale adsorbed gas content analysis system, a sample jar in which an adsorbent is put is arranged in a heating furnace; an adsorbent is arranged in the sample jar; a seal cartridge is arranged at the opening of the sample jar; a temperature measuring thermocouple is arranged in the sample jar; a temperature control thermocouple is arranged in the heating furnace; the temperature measuring thermocouple and the temperature control thermocouple both are connected with a control box; a gas storage chamber is arranged outside the heating furnace and communicated with the interior of the sample jar; a pressure sensor is communicated with the interior of the gas storage chamber and connected with the control box; a vacuum pump is arranged outside the heating furnace, communicated with the interior of the gas storage chamber and connected with the control box; and a tested gas tank and a protective gas tank are arranged outside the heating furnace, and both are communicated with the interior of the gas storage chamber. The shale adsorbed gas content analysis system is capable of accurately determining the content of the shale adsorbed gas and convenient for an analyst to perform subsequent analysis, and therefore, accurate data are provided for subsequent utilization of the shale gas.

Description

technical field [0001] The invention relates to a system, in particular to a shale gas adsorption gas content analysis system. Background technique [0002] Shale gas is an unconventional natural gas that occurs in organic-rich mud shale and its interlayers. It mainly exists in adsorption and free states. The main component is methane. It belongs to the same category as "coalbed methane" and "tight gas". . The formation and enrichment of shale gas has its own unique characteristics, and it is often distributed in thick and widely distributed shale source rock formations in the basin. Shale gas has been recognized by people for a long time, but it is more difficult to collect than traditional natural gas. With the increasingly scarce resources and energy, as a beneficial supplement to traditional natural gas, people gradually realize the importance of shale gas. Shale gas exists in kerogen, clay particles and pore surfaces in an adsorbed state (about 50%), and a very small ...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problem that the above-mentioned existing measuring system is not strictly designed for the adsorption situation, so that the error in the determination of the shale gas component content is very large, resulting in a lot of trouble in the subsequent utilization of shale gas, and a shale gas is designed. Rock gas adsorption gas content analysis system, the system can accurately measure the content of adsorbed gas in shale gas, which is convenient for analysts to carry out subsequent analysis, so that the subsequent use of shale gas can obtain accurate data, which is convenient for processing and utilization, and solves the problem of Due to the inaccurate design of the existing measurement system for the adsorption situation, the error in the measurement of the shale gas component content is very large, which leads to a very troublesome problem in the subsequent utilization of shale gas
