| 摘 要： | 阿克库勒凸起西缘东河砂岩发育良好,但其岩性及其储集物性与塔里木盆地其它地区的东河砂岩相比则相差甚远。岩石类型主要有砂岩、泥岩及泥-粉砂过渡岩类。砂岩是区内主要的储集层。物性分析资料表明,储层以中-差为主,并且在垂向上与横向上均具有极强的非均质性。综合分析表明,储集物性的这种非均质性除了受层序格架中体系域控制之外,主要还受成岩作用的控制,尤其是碳酸盐的胶结与东河砂岩顶部Ⅰ型层序边界的大气淡水淋滤溶蚀作用的控制。另一方面,高频海平面升降变化导致储层的储集物性在垂向上形成颇具特色的“韵律层”。

| Abstract: | On the western margin ofAkekule Up lift, the Donghe Sandstone develops very well, however, its lithology and reservoir features are different from that of other areas in Tarim basin. The main rocks are sandstone, mudstone and muddy siltstone or siltymudstone. And the sandstone is the main reservoir in this area. The analysis data of physical p roperties demonstrate that the reservoir properties of the rock in this region are middle to poor. And the properties have intensive heterogeneity vertically and laterally. Integrated analysis show that the reservoir non-homogeneity is controlled by not only the system tract in the sequence framework and also the diagenetic p rocess, especially by the cementation of carbonate and the eluviation's p rocess of the fresh water on the sequence boundary of typel. On the other hand, high frequent sea-level changes induced to form the special rhythm intervals of reservoir physical properties vertically. |
