Abstract

The invention relates to a gas rapid measuring analysis meter and a measuring method thereof. The analysis meter comprises a gas collecting cylinder, an infrared gas detection sensor and a flow sensor, wherein the gas collecting cylinder is provided with an air inlet hole and an exhaust vent, and the infrared gas detection sensor and the flow sensor are arranged on the air inlet hole. The measuring method comprises the following steps of: opening the exhaust vent, taking the smallest hole of a manual bore diameter flow regulating turntable to aim at the exhaust vent, filling saturated salt water in the gas collecting cylinder from the air inlet hole; after filling the saturated salt water, closing control switches of the air inlet hole and the exhaust vent, determining the small hole corresponding to the manual bore diameter flow regulating turntable and a drain hole when the saturated salt water does not flow out, and then closing the drain hole; opening the air inlet hole, utilizing the air inlet hole to connect in a rock sample sealing tank, and enabling the determined small hole in the last step to be aligned with the drain hole; introducing the gas into the gas collecting cylinder, and discharging the same voluminal saturated salt water from the drain hole; and collecting and recording the data. The gas rapid measuring analysis meter and the measuring method provided by the invention have the advantages that the gas collecting operation is simple, and the gas rapid measuring analysis meter is suitable for bring the field experimentation.

Description

technical field [0001] The invention relates to the field of testing the content of adsorbed gas in gas-containing samples, in particular to a gas rapid measurement analyzer and a measurement method thereof. Background technique [0002] Adsorbed gas refers to the natural gas that exists in the organic matter, pores and fracture surfaces of the reservoir in an adsorbed state. In conventional natural gas reservoirs, the content of adsorbed gas is very low, generally less than 20%. In unconventional natural gas reservoirs, the content of adsorbed gas is relatively high. The content of adsorbed gas in shale gas reservoirs is 20-85%. The adsorbed gas content of layered natural gas is generally greater than 85%. The adsorbed gas content is directly related to the quality of unconventional natural gas aggregates and the corresponding technologies required in the development process, especially for unconventional natural gas such as coalbed methane and shale gas, the adsorbed gas ...
