| 摘 要： | 埕北低凸起东斜坡地区东营组储层的储集砂体主要为石英砂岩、长石砂岩和长石质石英(杂)砂岩。孔隙是储集层的主要储集空间,主要有粒间孔、溶蚀孔、微孔隙三种类型。在综合分析储层的物性和孔隙的结构特征的基础上,对该地区储层进行了综合分类评价,将砂岩储层划分为四个类型。储层的发育受沉积作用和后期成岩作用控制。沉积环境从宏观上控制了储层的发育,而压实、胶结和溶蚀作用在微观上影响了孔隙的演化与储层物性的变化。对于埋藏较深的储层,成岩作用对储层的质量起着决定性的作用。

| Abstract: | The Dongying Formation sandstone reservoirs in the eastern slope zone of the Chengbei low uplift in the Bohai Bay are made up of quartz sandstone,arkosic sandstone,and feldspathic quartz sandstone(greywacke).The rock pores constitute the main reservoir spaces,and the pore structures include intergranular pores,solution openings and micropores.The development of the sandstone reservoirs is controlled by deposition and subsequent diagenesis.Macroscopically,the sedimentary environments have exercised a major c... |
