摘　　要：通过对国内 15个含油气盆地 10余万块砂、泥岩样品黏土X射线衍射分析资料和地质特征的分析 ,将我国含油气盆地的黏土矿物组合划分为两大类共 12种 ,分别代表不同的沉积和成岩环境。常见黏土矿物组合类型中 ,组合 1～ 5分别代表早成岩A、B及晚成岩A、B、C等 5种不同的成岩环境 ,组合 6常见于高渗透储集层或煤系地层 ,组合 7多见于生油凹陷中的低渗透储集层 ;特殊黏土矿物组合类型中 ,组合 8反映膨润土夹层 ,组合 9反映造山带深部地层不断剥蚀的快速堆积环境 ,组合 10反映基性火山岩物源 ,组合 11反映快速剥蚀堆积或富钾的沉积环境 ,组合 12反映干旱富镁的沉积环境。图2参 3 (王行信摘 )The combination pattern of associated clay minerals are classified into two major categories with twelve types by geological feature and X ray diffraction analyses of more than one hundred thousand samples of sandstones and mud rocks fifteen petroliferous basins of China, each type represents different sedimentary and diagenetic environments respectively. The first to the fifth normal types represent five kinds of different diagenetic environment that include early diagenetic stage A and stage B, and later diagentic stage A, stage B, and Stage C. The sixth type commonly happens in high permeability reservoir or coal measures strata, the seventh one often happens in low permeability reservoir of oil generation depression. The five special types of combination pattern of associated clay minerals represent the following different sedimentary environments:(1)bentonite band; (2)the environment of continuous denudation of deep stratum and quickly accumulation; (3)source area of basic volcanic rocks; (4)the sedimentary environment of quickly degradation and accumulation of potassium rich materials and (5)the arid sedimentary environment of magnesium rich materials.
