摘要
简要论述了济阳坳陷地层型油气藏的分类及分布特征。根据地层型油气藏与不整合面的关系首次提出"不整合体"的概念。分析了不整合体对不同类型地层型油气藏作用的差异性,建立了不同的成藏模式。探讨了地层型油气藏的成藏机理,指出浮力是地层型油气藏油气运移的主要驱动力、构造应力的突然释放是油气幕式运聚的触发机制、地层型油气藏的成藏过程表现为具幕式特征的相对连续过程。
The paper briefly discussed the classification and distribution of the strata reservoirs in Ji Yang depression. It presented the concept of 'unconformability body' for the relation of strata reservoir and unconformability contact. Analyzed the differences when the 'unconformability body' impacted on difference types of strata reservoirs. Some different reservoir forming modes were constructed. It discussed mainly the mechanism of strata reservoir forming, concluded that first their reservoir forming dynamic is buoyancy and the second the structure stress. The buoyancy is the main dynamic for the oil & gas migration in strata reservoirs and the abruptly releasing of stress is the spring mechanism of the oil & gas episodic migration. The strata reservoirs forming show a relative continuous process with episode.
