摘要

该文从断陷盆地隐蔽油气藏勘探实际出发,以隐蔽油气藏形成的主控因素为主线,系统分析了以断裂为主要表现形式的构造运动对沉积(储层)的控制作用,建立了断陷盆地"断坡控砂"模式;研究了断陷盆地输导体系类型及构成要素,提出了"网毯式"、"T-型"、"阶梯型"和"裂隙型"输导体系及其空间构成的复式输导关系;系统分析了"相"、"势"在油气成藏中的作用及耦合关系,提出了"相势控藏"的理论认识。

Abstract

The critical controlling factors of subtle reservoir formation was researched systematically from the viewpoint of explorative practice for subtle oil pools in fault basins. The model of fault slopes controlling sandbodies in fault basins was built based on the analysis of the controlling effects of tectonic activities, which took faulting as the main behavior form, on reservoirs. By studying on the types and constitutional elements of transportation systems in fault basins, four types of transportation systems were pointed out, that is, the meshwork-carpet type, the T type, the ladder type and the fracture type. And their vertical and lateral multiple transportation relations were also described. After analysing on the effects of sedimentary facies zones and fluid potential on pool formation and their coupling relations, it was considered that sedimentary facies zones and fluid potential controlled pool formation in fault basins.
