Device for measuring loss amount of water-soluble methane in coalbed methane and implementation method of device

Abstract

The invention discloses a device for measuring the loss amount of water-soluble methane in coalbed methane and an implementation method of the device, and belongs to the technical field of methane loss amount measurement, the device comprises a mounting sleeve, an outer sleeve is connected below the mounting sleeve, the inside of the mounting sleeve and an outer sleeve are respectively coated withan inner sleeve, a supporting rod is arranged above the mounting sleeve, and a supporting bedplate is arranged above the supporting rod. According to the device for measuring the loss amount of the water-soluble methane in the coalbed methane and the implementation method of the device, the separation efficiency is improved, the collection speed is increased, gravel is effectively filtered through the filter screen, blockage in the pipe is avoided, different stored particles are filtered through the double filter needles, an airflow outlet is prevented from being blocked, smooth ascending ofgas is guaranteed, and the methane collection efficiency is improved; the gas drainage is fully increased, the gas waste is reduced, the cost is reduced, the resources are saved, the environment is protected, the water-soluble methane loss amount in the coalbed methane is effectively detected, and data extraction is facilitated for later research.

Description

technical field [0001] The invention relates to the technical field of methane loss measurement, in particular to a water-soluble methane loss measurement device in coal bed gas and an implementation method thereof. Background technique [0002] Coalbed methane refers to the hydrocarbon gas stored in coal seams with methane as the main component, commonly known as "gas", which is an associated mineral resource of coal and belongs to unconventional natural gas. As the main component of coalbed methane, methane is considered to be a clean and low-carbon transitional energy source. The important reason is that the full combustion of methane produces less CO2 than other fossil energy sources. But methane is also the second-largest greenhouse gas in the atmosphere, second only to CO2 in contributing to global warming over history. Methane is buried in coal seams hundreds of meters to 2 kilometers underground, often accompanied by a large amount of coal seam water. During the pr...

Problems solved by technology

[0003] The purpose of the present invention is to provide separate transportation of water and gas through the layering of the outer casing and the inner casing, improve the separation efficiency, increase the collection speed, the filter screen can effectively filter the sand and gravel, and avoid the blockage in the pipe, and the double filtration is aimed at different storage conditions. Filter the particles, change the pressure in the inner sleeve, so that the water flow is concentrated into the inner sleeve, prevent the blockage of the air outlet, ensure the smooth rise of the gas, improve the efficiency of methane collection, fully increase the exhausted gas, reduce the waste of gas, and save costs. It saves resources and protects the environment. Through the conversion of flow and pressure, the data of the concentration of water-soluble methane in coalbed methane can be obtained, and the loss of water-soluble methane in coalbed methane can be effectively detected. It is convenient to propose data for later research. Measuring device for water-soluble methane loss in coalbed methane and its implementation method to solve the problems raised in the above-mentioned background technology
