Abstract

The invention discloses test-bed equipment for testing the shale gas content. The test-bed equipment comprises an operation platform, positioning circular pipes, a water tank water inlet flange, airtight gas tanks and desorption tank drainage pipes. The airtight gas tanks are inserted and fixed inside fixed rings which are welded and fixed to the outer wall of the right side of the operation platform; the desorption tank drainage pipes are welded and fixed to the outer wall of the left side of the operation platform and penetrate through the operation platform to communicate with the interiors of desorption tanks; water guiding spiral pipes, gas tank water outlet pipes and gas flowing pipes are all hoses and are connected with metal connectors on the desorption tanks and the airtight gas tanks in a manual sleeving-inserting mode. The test-bed equipment for testing the shale gas content is provided with the desorption tanks, electric heating pipes are fastened at the bottoms of the desorption tanks in a threaded mode, and heating pipes of supporting plates with holes are welded to the inner walls of the desorption tanks so that water inside the desorption tanks can be heated; the temperature of sampled shale in underground lithosphere is simulated, so that the maximum amount of shale gas can be desorbed from the sampled shale, and accordingly the shale gas content is more accurately tested.

Description

technical field [0001] The invention relates to the technical field of test bench structures, in particular to a test bench equipment for shale gas gas-bearing testing. Background technique [0002] Shale gas refers to unconventional natural gas that occurs in organic-rich shale-dominated reservoir rock series. It is continuously generated biochemical gas, thermogenic gas or a mixture of both, and can exist in natural fractures in a free state. It exists in the surface of kerogen and clay particles in an adsorbed state, and a very small amount is stored in kerogen and asphaltene in a dissolved state. The proportion of free gas is generally 20% to 85%. [0003] The inventors found that the existing test bench equipment for shale gas gas-containing testing needs to be manually added water when used in the sampling site, and the test operation cannot be performed in batches. There is no special heating equipment, and the heating simulation page The temperature of the rock in t...
