[0002] When liquid carbon dioxide is heated and turned into gas, its volume is more than 600 times the original volume, and it will generate huge pressure on surrounding objects during the expansion process. This technology applies pressure to the surrounding coal body through the "carbon dioxide fracturing device" and uses the coal-loving properties of carbon dioxide to effectively displace coal seam gas. It can solve the problem of extraction from low-permeability coal seams and change the current situation where coal seams with low gas content cannot or are difficult to extract and utilize. In order to be able to extend into the coal seam, an auxiliary device for pushing and pulling the carbon dioxide permeability enhancement and desorption device is provided.

[0003] A carbon dioxide fracturator is a tool used for shale gas or coalbed methane extraction. Its principle is to use high-pressure carbon dioxide to release natural gas from coal seams or shale strata. The working principle of a carbon dioxide fracturator is to use high-pressure CO2 gas to expand and connect the cracks inside coal seams or shale strata, thereby releasing natural gas.
