| Abstract: | A review of China's present coalbed gas exploration and development with 4 types of techniques(surface vertical well,gob well,underground gas extraction,gas extraction from abandoned mine),combined with domestic and international development trends,is presented in this paper.The authors indicated that it is important to increase the study on coalbed gas reservior formation,permeability controlling factors of anthracite,the basic theory on low rank coal's resource,as well as the research on advanced techniques of low damage,gas injection for increasing production,tight radius of curvature drilling operation. |
