摘要
葡北东斜坡、葡萄沟地区长期位于油气运移的指向区,储层发育、油源条件好,展示了位于葡北-葡萄沟地区的隐蔽油气藏具有较大的勘探潜力。该区低幅度构造圈闭和隐蔽油气藏形成应该具备以下地质条件:①储层物性控制圈闭的有效性,储层物性是油气注入的先决条件;②近源的砂体圈闭有利于油气藏的形成;③与构造或断层配置关系良好的圈闭形成复合型油气藏;④薄砂层发育的相带有利于油气藏的分布。
Pubei Eastern slope and Putaogou region are located in the direction of the oil-gas migration for a long time,and the reservoir development oil sources conditions are excellent,which display great exploring potential of lithologic hydrocarbon reservoir in Pubei-Putaogou.The formation of subtle reservoir in the area should has the following geological conditions：① Reservoir quality control the effectiveness of lithologic traps and it is a prerequisite for the hydrocarbon accumulation;② The lithologic traps near the source is in favor of the formation of hydrocarbon reservoirs;③ The traps on good terms with the structure or the fault allocation forms the composite system/reservoir;④ The facies belt developed from thin sand layer is helpful to distribution of lithologic reservoirs（pool）.
