| 摘 要： | 江陵凹陷新沟咀组下段粘土矿物组合与分布受沉积环境影响明显,高岭石仅分布于三角洲平原相带中,粘土矿物以伊利石、高岭石和有序-无序伊蒙混层及少数绿泥石为特征;三角洲前缘相中粘土矿物组合则为伊利石、绿泥石和有序伊蒙混层;前三角洲及湖盆泥岩相中则以伊利石和绿泥石两种粘土矿物为主.储层的敏感性实验结果表明,本区储层具有中等强度速敏、强-特强水敏、强盐敏和强酸敏性.

| Abstract: | The combination and distribution of clay minerals in lower section of Xingouju Formation of Jiangling sag are obviously controlled by the sedimentary environment,kaolinite exists only in delta plain facies,the minerals are characterized by illite,kaolinite,ordered to disordered illite/montmorillonite mixing layer and small amount of chlorite.The clay minerals combination in delta front facies include illite,chlorite and ordered illite/montmorillonite mixing layer.The two main clay minerals in prodelta and l... |
