摘要
综合运用油源对比、断裂-砂体研究、油藏充注史分析等方法,对东营凹陷梁家楼地区输导体系进行了研究,认为梁家楼油田下第三系沙三中、下亚段及沙四上亚段有效烃源岩主要通过同生断层与沙三上亚段储层连通,垂向运移是本地区油气主要运移方式,断层是输导体系的主要组成部分,断层活动期次控制油气运移期次,有效烃源岩分布和断裂活动方式共同决定了油气运移模式。
As a important part of the reservoir mechanism research, not only the static description of the geological bodies, but also the dynamic attention of petroleum migration should be considered together in the passage system study. Based on the correlation between oil and source rocks, analysis of faults and sand bodies, and the analysis of oil accumulation history, this paper discusses passage system of Liangjialou oil field in Dongying sag. This paper suggests that the effective source-rocks in the upper part of the fourth stage, the middle and lower parts of the third stage of Shahejie Formation were connected with reservoir through synsedimentary faults, and the vertical migration was the major type of accumulation in Liangjialou oil field. The growth fault is the most important element in the passage system, and the accumulation stage is determined by the active stage of faults. The model of petroleum migration is controlled by the distribution of effective source rocks and the motion type of faults.
