【摘要】 本文首先阐明地层岩性圈闭形成的地质背景,在沉积盆地中不同类型砂体及其分布控制岩性圈闭成因,与成油岩系有关地层超覆不整合面是形成地层圈闭的重要条件。还论述形成地层岩性圈闭的六个基本要素,它们之间有机配合可形成不同类型地层岩性圈闭。重点论述了地层岩性油藏聚集带类型及其形成条件。在区域地质结构及其演化史,湖盆沉积体系和地层不整合等因素控制下,在同一类型盆地中不同类型构造岩相带形成不同类型地层岩性油藏聚集带。不同类型含油气盆地中,地层岩性油藏聚集带类型和展布方式是不同的。最后,对地层岩性油藏的勘探效果作了初步分析,还进一步阐明了地层岩性油藏的研究方法、内容和勘探程序。更多还原

【Abstract】 This paper firstly describes the geological setting for the formation of litho-stratigraphic traps:different types of sand bodies and their distribution in a sedimentary basin controlled the genesis of lithologic traps and the stratigraphic overlap unconformity related to oil-forming rock series contributed significantly to the formation of stratigraphic traps.Six basic elements forming litho-stratigraphic traps and their organic coordination which can form different kinds of litho-stratigraphic traps are also discussed in the paper.In the discussion,emphasis is put on the types and formation conditions of litho-stratigraphic oil accumulation zones.Under the control of regional geological texture and its evolution history and that of sedimentary system in the lake basin and stratigraphic unconformity,different types of litho-stratigraphic oil accumulation zones could form in different types of structural facies in the same kind of basins.The type and distribution pattern of litho-stratigraphic oil accumulation zones also are different in distinct petroliferous basins.A preliminary analysis of the effect of exploration for litho-stratigraphic oil pools as well as a further discussion on their research and exploration procedures are made in the final section of the paper.更多还原
