| Popis: | Coalbed methane (CBM) is a new environmentally friendly unconventional energy source of great promise for exploitation. The CBM resources in the Qinshui Basin are as great as 3.97 × 1012 m3, i.e., 10.8% of the total coal gas resources of China. Compared to the main coal basins of the United States, Australia, Canada, and Russia, the Qinshui Basin is characterized by high metamorphism, high gas content, and low values of porosity and permeability, as well as by low formation pressure. The commercial exploitation of productive beds at the Qinshui Basin requires the use of efficient technologies of stimulation. Vertical wells with hydraulic fracturing (HF) predominate at the Qinshui Basin. The CO2 injection, electric pulse, multistage HF, etc. technologies are used as well. |
