摘　　要：应用岩石薄片、扫描电镜及能谱等微观实验技术,分析彩9井三工河组储层岩石中敏感性矿物的亚族类型及其分布产状形态、分布位置等微观特征,同时对岩石做敏感性流动实验。分析结果表明储层岩石中速敏性矿物高岭石和膨胀性过渡型绿泥石互相依附叠置的特殊分布形态,是造成储层存在较强水敏性的内在原因。从而解释了常规岩石学分析储层敏感性伤害与岩石敏感性流动实验结果存在的矛盾。Using the micro-experiment techniques such as rock section and scanning electron microscope and energy spectrum etc,we can analyze the micro-characters of subtribe type and formation distribution and the site distribution etc.of sensitivity minerals,which were in the storage of cai-9 well Sangonghe formation.And at the same time we can do the sensitivity flowage experiment of rock.The result showed that the special distribution form of Kaolin and Chlorite was the immanent cause to make the water sensitivity of storage stronger,which were adhered and superposed with each other.And this was the reason why the analysis results existed contradiction between the routine petrology and the sensitivity flowage experiment of rock.
