煤层气储层损害机理与保护钻井液的研究

采用X射线衍射、扫描电镜、泥页岩膨胀实验、页岩分散实验、薄片分析、压汞分析、润湿性测试和敏感性评价等手段分析了山西沁水盆地煤层气储层的损害机理。在此基础上进行了针对性的保护对策研究,优选出了表面润湿性改善剂SD-905,水敏性抑制剂SMYZ-2,并最终研制出了山西沁水盆地煤层气储层的钻井液：0.4%SD-905＋0.5%SMYZ-2溶液,其对煤层气储层岩样湿态下的渗透率损害最低。...

Bibliography: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.
