摘　　要：油气成藏体系是针对中国陆相叠合盆地提出的油气系统研究新概念,是含油气系统的进一步发展。它是相对独立的油气运聚单元,以"藏"为中心,包括形成油气藏的一切必要元素,即烃源体、输导体和圈闭体,以及这些元素之间的有效配置结构。油气成藏体系可划分为单源一位、单源二位、单源三位、二源二位、二源三位和三源三位共6种结构类型。元素定量评价揭示油气成藏体系内部单元的质量优劣,其关键是地质单因素的选取;成熟度定量描述油气成藏体系的发育演化程度和过程,可将其划分为未成熟、成熟和过成熟3种类型。油气成藏体系适用于多源、混源型油气藏研究,加强系统动态演化和油气分布规律研究,可有效指导探区油气资源和成藏组合评价。Petroleum accumulation system is a new system concept brought up for China continental superimposed basins, which is the further development of petroliferous system. It is a relatively independent hydrocarbon migration and accumulation unit, which centers on 'reservoir', including all the necessary elements of reservoir formation as source rock, transportation system, trap, and their effective configuration. It can be divided into 6 types: one source one space, one source two spaces, one source three spaces, two sources two spaces, two sources three spaces, and three sources three spaces. The quantitative evaluation of elements in the petroleum accumulation system reveals its internal quality of every unit with the key of single geological element. Petroleum system mature index describes its development degree and evolution process quantitatively, which can be divided into three types of unmature,mature and postmature. Petroleum accumulation system suits for multi-source and mixed-source hydro-carbon reservoirs. Enhancing the research of system dynamic e-volution and hydrocarbon distribution regularity will effectively guide the oil and gas resources and assemblages evaluation of the exploration area.
