| 摘 要： | 潜江凹陷单向多物源的盐湖沉积体系及构造背景决定了其具有形成多种成因类型岩性油藏的地质条件，按圈闭成因将潜江凹陷岩性油藏分为4亚类15小类。砂岩尖灭线与构造的有机配合是形成岩性油藏的主要因素。纵向上，岩性油藏主要发育于潜三-潜四段，平面上主要发育于面迎物源的构造上倾斜坡和断层与砂岩侧缘尖灭配置集中分布区。

| Abstract: | The unidirectional,multi-source,saline-lake sedimentary system and structural background of the Qianjiang subbasin are the necessary geological conditions for the formation of a number of genetic types of lithologic reservoir in the Qianjiang saline lake.The lithologic reservoirs may be divided into 15 subtypes of 4 types.The organic combination of sandstone pinchout line and structure is the major factor responsible for the formation of the lithologic reservoirs.Vertically,lithologic reservoirs mostly occur in the Third and Fourth members of the Qianjiang Formation,and in plan view,they are mainly developed on the structural slopes facing the material source and in areas where the combinations of faults and sandstone edge pinchout are concentrated. |
