Abstract

The application provides a rock and gas multi-process coupling test device for unconventional natural gas, the device is characterized by comprising a first clamping mechanism, a second clamping mechanism and a differential pressure sensor, wherein pipelines at both ends of the first clamping mechanism and the second clamping mechanism are provided with first electromagnetic valves; pipelines at both ends of the differential pressure sensor are provided with manual valves; the differential pressure sensor 3 is connected in parallel with a second electromagnetic valve. The aim of designing anddeveloping the device is that the system can carry out a true triaxial experiment on shale carbonaceous, the system finds out a relationship of permeability of a coalbed methane reservoir in the developing process and an effective stress element and can reasonably determine a development mode of coalbed methane.

Description

Technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a rock and gas multi-process coupling test device for unconventional natural gas. Background technique [0002] The existing technology does not have such a device. The device in the phantom can simulate the process of coalbed methane accumulation, adsorption, and desorption under the conditions of formation temperature, pressure, and formation fluid medium. The use of advanced computer software technology to achieve the dynamic test of coal sample adsorption; use of external heating [0003] The device causes the coal sample to undergo oxidation and heat generation reaction. Simulate the real conditions of the surface layer to carry out in-depth scientific experiments to find out the best plan for reasonable oil and mining to maximize the benefits. Therefore, it is necessary to provide such a device to solve the above technical problems. Summary of the invention [0004]...
