Device for measuring gas content of shale gas in shale

Abstract

The invention discloses a device for measuring the gas content of shale gas in shale; the device comprises a sealed measuring box body; the side wall of the middle of the sealed measuring box body isprovided with a feeding port, and the lower side of the sealed measuring box body is also provided with a bottom base plate; the upper end face of the bottom base plate is connected and fixed with thebottom wall of the sealed measuring box body through a plurality of support rod columns; a fixed transverse plate is connected between the support rod columns; the outer side wall of the bottom end of an adjusting rotating shaft is provided with a spiral section in threaded fit with the fixed transverse plate, the upper end face of a placement mesh plate is provided with grinding bulges, and thelower end face of a crushing baffle mesh plate is provided with press-crushing teeth; the side wall of the bottom of the sealed measuring box body is connected with a water inlet guide pipe; the interior of a left chamber communicates with the top of the sealed measuring box body through a gas discharge guide pipe; the middle part of the gas discharge guide pipe is also provided with a gas extraction pump and a moisture absorber; and the side wall of a measuring cylinder is also provided with a second scale. The device has the advantages of simple structure, accurate determination of the shalegas content, convenient operation and high practicability.

Description

technical field [0001] The invention relates to the technical field of shale gas measuring equipment, in particular to a device for measuring the gas content of shale gas in shale. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale and its interlayers, mainly in the form of adsorption and free, and is mainly composed of methane. It is a clean and efficient energy resource and chemical raw material , mainly used for residential gas, urban heating, power generation, automobile fuel and chemical production, etc., with a wide range of uses. In the production process of shale gas, drainage is generally not required, and the production cycle is long, generally 30 to 50 years. The success rate of exploration and development is high, and it has high industrial economic value. In the process of shale gas exploration and development, it is also necessary to test the gas content of gas-bearing shale samples accordingly. Duri...

Problems solved by technology

But at the same time, the existing problem is that for the existing measuring devices, the natural desorption time of the shale samples is often longer during the use process, which leads to the greatly prolonging of the measuring test period, which greatly limits the The efficiency of the determination test also affects the performance of the determination device accordingly
