摘要：

孔店组和沙四段在惠民、东营凹陷是重要的含油气层位,其构造演化可划分为4个阶段,即孔店-沙四期伸展半地堑充填阶段、沙二-沙三期断块强烈活动阶段、沙-东营期断块活动复杂化阶段和晚第三纪-第四纪埋深加大阶段。与此对应孔店组-沙四段中断层的演化序列为板式→铲式→坡坪式;断陷构造样式的演变序列为旋转半地堑→滚动半地堑→复式半地堑。惠民凹陷孔店-沙四期伸展强度最大,东营凹陷沙二、沙三期伸展强度最大。受构造影响,形成沙河街组四段好的烃源岩,且惠民凹陷比东营凹陷更发育。与孔店组和沙河街组四段有关发育二个正常式生储盖组合。断层是主要的运移通道。构造圈闭主要是与断层有关的断块和断鼻。凹中隆地区和边缘斜坡地区是油气成藏的最有利部位。

Abstract:

Kongdian Formation and the fourth member of Shahejie Formation are important oil-gas-0bearing formations in Huimin-Dongying Depression.Their tectonie evolution can be divided into four stages, e. i. the filling of extensional Half-graben, strong fault-block movement, the complication of fault-block movemenmt and deep buried stages.Accordingly, the fault evolution series is plate→listic→Ramp and flat patterns in Kongdian Formation and the fourth Member of Shahejie Formation. The evolution series of Huimin-Dongying Depression was the rotational half-graben→Rolling half-graben→complex half-graben. The fourth member of Shahejie Formation was favourable source rock due to The effect of teotonic movement, Kondian Formation and the fourth member of Shahejie Formation developed into two Sets of normal source-reservoir-cap rock assemblage. The faults in the basin are the main migration paths, and the main Traps are fault-blacks and fault-noses. The uplifts in the depression and marginal slopes are the most favourable sites for oil-gas accumulation.

Key words: Huimin-Dongying Basin, tectonics, oil-gas, relationship
