Trial production of surface CBM well is the key link to realize exploration and conversion production. From 2019 to 2021, CCTEG Xi 'an Research Institute undertook "Coal-bed methane Exploration Project of Wenjiazhuang Mine" technology transformation project of Huayang New Material Technology Group Co., LTD. Up to now, four CBM test wells have entered the drainage stage. Among them, PS06 well has a daily gas output of 1159m3. The other three coalbed methane trial wells have started producing with quite positive gas potential. The successful implementation of the project has strengthened the determination of ground pre-drainage gas control in this region and laid a good foundation for the follow-up cooperation between the two sides.
