【摘要】 岩性地层圈闭的形成与分布主要取决于盆地的地质构造背景、地层的空间分布、特定的沉积环境及后期构造运动的影响。以层序地层学、地震地层学的理论为指导,从寻找岩性地层圈闭角度出发,分析了岩性地层圈闭的类型、赋存条件及勘探难点,提出了以富油凹陷为目标,以查明“三面一线”(最大湖泛面、首次湖泛面、不整合面及勘探目的层尖灭线)为基础的勘探思路和开展岩性地层圈闭工业制图及其质量检查的建议。相信这些建议不仅使今后的岩性地层圈闭工业制图逐步标准化,也有助于促进岩性地层圈闭解释研究工作的不断深入,发现和预测更多的岩性地层油气藏。更多还原

【Abstract】 The formation and distribution of lithologic-stratigraphic traps are dependent on the geological structural background, space distribution of strata, special deposition environment of the basin, and the effect of later structure events. With the theory of sequence stratigraphy and seismic stratigraphy, it analyses the various types of lithologic-stratigraphic traps, their occurrence conditions and the exploration difficulty, and also proposes the exploration thinking that builds in the basement of finding out "three surfaces and one line" (i.e. maximum flooding surface, initial flooding surface, unconformable surface and pinchout line) in oil-rich sags and the suggestions that include mapping for lithologic-stratigraphic traps and checking the interpretation quality in the term of lithologic-stratigraphic traps. The suggestion is not only helpful for mapping standardization of lithologic-stratigraphic trap, but also to promote deepening the interpretation of lithologic-stratigraphic traps and discover more promising lithologic-stratigraphic oil reservoirs.更多还原
