| 摘 要： | 根据粘土矿物演化、有机质演化、成岩矿物特征、阴极发光、铸体薄片以及包裹体等方面研究，厘定了渤南洼陷沙四上亚段目前处于成岩晚期A2-B亚期；建立了渤南洼陷深部储层成岩演化序列，阐明了粘土矿物及其演化是储层形成的序参量；研究了渤南洼陷沙四上亚段成岩作用。重点探讨了泥岩和砂岩中粘土矿物对深部储层的影响——砂岩储层中的无机成岩作用与生油岩中的有机质成岩作用密切相关，二者相互作用的结果使邻近储层铝硅酸盐颗粒和碳酸盐溶蚀，形成次生孔隙；且发现高岭石大量出现是次生孔隙发育的一个标志，预测3600m附近极有可能存在一次生孔隙发育带。

| Abstract: | The chemical evolution of clay minerals and organic materials, features of rock-forming minerals,cathode-luminescence and microscope identification as well as features of fluid inclusions show that the upper part of the Shasi Member in Bonan subsag is in the subphase A 2-B of late stage of diagenesis. The diagenetic sequence of the deep reservoir of the Bonan subsag has been set up. It has been especially discussed that clay minerals of argillite and sandstone have the most important effects on deep reservoir. It is concluded that inorganic diagenesis of sandstone reservoir shows close relationship with organic diagenesis oil-host strata, and solution of aluminium-silicate and carbonate diagenesis produced secondary voids with large amount of forming of kaolinites. It has forecasted that a secondary void zone might exist about 3600 m below the surface. |
