Abstract: The capacity bottleneck of coalbed meathane wells in China is prominent. Conventional reservoir reconstruction measures mostly have the characteristics of destroying production matrix and controlling the direction of fracture extension. In order to explore a more efficient and environmentally friendly reservoir reconstruction technology, combining the formation mechanism and production mechanism of coalbed meathane, a simple and efficient plasma pulse technique is introduced, which has been successfully applied in oil and gas fields, and its treatment method is simple and efficient. Based on the principle of plasma pulse technology, 4 wells in Sihe and Zhengzhuang blocks in Jincheng mining area were optimized on the basis of a certain principle of well selection. The applicability of the technology has been tested. The results show that the periodic broadband wave produced by the plasma pulse technique helps to stimulate the resonance effect in the coal reservoir system. A large number of expansion fracture networks are developed on the basis of the primary fissure, and the gas channel and the near well zone blockage can be stripped to increase the reservoir permeability. Coalbed methane well production practice further confirmed that the application of plasma pulse technology for coal reservoir reconstruction has achieved good results, the technology is worthy of popularization and application.
