摘要/Abstract

摘要： 地层油气藏分为地层不整合体油气藏、地层不整合遮挡油气藏、地层超覆油气藏和生物礁油气藏等4种类型。不整合发育的层状结构为油气成藏提供了有利条件,在不整合构造体内部,不整合面的上、下都发现有油气藏的存在。这种新的类型被定义为地层不整合体油气藏,它以不整合结构体体系内成藏为特点。地层不整合遮挡油气藏主要以削截不整合和褶曲不整合类型为主,超覆带易于形成复合型地层油气藏。地层油气藏与不整合关系密切,具有明显的成藏规律。不整合展布具有区带性;与传统上把不整合理解为遮挡性面状体的认识不同,不整合还能提供优质的储集空间;不整合油气成藏受多因素影响,并对油气成藏具有重要的指示作用。

Abstract: Stratigraphic reservoir is divided into four types such as stratigraphic unconformity system reservoir, stratigraphic unconformity barrier reservoir, stratigraphic onlap reservoir and biohermal reservoir. The unconformity has developed layered textures, which provide favorable conditions for hydrocarbon accumulation. Hydrocarbon reservoirs are all found in the upper and the lower of unconformable surface. Such a new type of reservoir is defined as the stratigraphic unconformity system reservoir which is characterized by hydrocarbon accumulation within the unconformity structural system. The stratigraphic unconformity barrier reservoir is dominated by truncated unconformity and folded one. The overlap belt tends to shaping complex stratigraphic reservoir. Therefore, stratigraphic reservoirs are all closely related to unconformity, and possess distinct patterns for hydrocarbon accumulation. The distribution of unconformity is of play propery. Different from conventional recognition regarding the unconformity as barrier-like planner system, unconformity could provide premium storage spaces. The unconformity hydrocarbon accumulation or reservoir is affected by several factors, but unconformity is of instructed effect on the hydrocarbon accumulation.

Key words: stratigraphic reservoir, reservoir type, stratigraphic unconformity system reservoir, hydrocarbon accumulation pattern
