Abstract

The invention discloses an on-site shale gas desorption analyzer. The on-site shale gas desorption analyzer disclosed by the invention is compact in overall structure and low in experimental environment requirements and is applied to convenient on-site testing of a vehicle-mounted room or simple room nearby a well site. The analyzer is low in power, and power of the analyzer can be supplied by a generator or supplied conventionally. According to the set of instrument, the content of gas of a shale gas site can be tested, the content of gas of tight gas reservoir, coal bed gas and other site rock cores also can be tested, and the accuracy is high. According to the well site customer test requirements, the rapid site shale gas desorption analyzer can be connected with an on-line gas analyzer, and gas components and change in the shale gas desorption process can be synchronously analyzed. The components of the shale gas can be rapidly determined, and the degassing rule can be researched. The on-site shale gas desorption analyzer is equipped with a rapid gas sample production joint, and the gas separated from rock core samples can be conveniently collected to be used for subsequent accurate testing and analysis in a lab, such as gas component analysis and gas isotope analysis in the lab.

Description

Technical field: [0001] The invention belongs to the technical field of shale gas preparation, and in particular relates to an on-site desorption analyzer for shale gas. Background technique: [0002] The shale gas on-site desorption analyzer is a device for the determination of shale gas content. It is an instrument for directly measuring the gas content of shale desorption at the shale gas well site. It mainly analyzes the lost gas and gas in shale gas. The desorbed gas is analyzed and calculated. [0003] The current conventional shale or coal rock well site is now measuring the desorption amount of equipment, because it is measured by the drainage method, it will cause the following disadvantages: [0004] 1. The water bath is heated, resulting in a large volume of the overall instrument, and due to the existence of liquid, it is not easy to carry. [0005] 2. It is necessary to observe the liquid level of the measuring cylinder or burette many times, which is easy to ...
