HUANG Wei-an1,QIU Zheng-song1,WANG Yan-qi2,MA Yong-le1,JIANG Lin1,ZHONG Han-yi1,BAI Xue-fei1(1.School of Petroleum Engineering,China University of Petroleum,Qingdao 266580,China;2.Research Institute of Engineering Techniques and Design,Petroleum Bureau of East China,Nanjing 210031,China)  
Firstly,damage mechanisms of coalbed methane reservoir in Qinshui Basin of Shanxi Province were comprehensively analyzed by X-ray diffraction(XRD),Scanning Electron Microscope(SEM),liner swelling test and hot rolling dispersion experiments,thin-section analysis,mercury penetration analysis,wettability measurement and evaluation of sensitivity.Based on this work,pertinent protection counter-measure study were conducted,the surface wettability modifier SD-905 and water sensitivity inhibitor SMYZ-2 were selected out,and then drilling fluid for coalbed methane reservoir in Qinshui Basin of Shanxi Province composed of 0.4%SD-905+0.5% SMYZ-2 was developed,which has minimal damage to permeability of ingredient under hygrometric state.
