从盆地构成的层次结构及油气藏特点出发,提出了基于陆相盆地的层次结构的油气成藏体系概念及划分方法,将济阳坳陷油气成藏体系划分为四级三类.四级:油气成藏体系组合、油气成藏体系、油气成藏组合和油气藏,三类:它源型前古近系基底潜山型油气成藏体系组合、自源型古近系中深层油气成藏体系组合、它源型新近系浅层油气成藏体系组合.阐述了各油气成藏体系组合及其内部单元的油气藏分布特点.
Based on the structure of the basin and the characteristics of oil and gas reservoirs, the concept and division method of oil and gas accumulation system based on the hierarchical structure of terrestrial basins are proposed, and the hydrocarbon accumulation system in Jiyang depression is divided into four classes and three classes. There are three types of hydrocarbon accumulation system combination, hydrocarbon accumulation system, hydrocarbon accumulation combination and oil and gas reservoir. They are the combination of the former Paleogene basement buried hill type hydrocarbon accumulation system and the self-source Paleogene mid-deep hydrocarbon accumulation System assemblage, which is a combination of shallow source rocks and gas reservoirs in the Neogene system of the source rocks, and expounds the distribution characteristics of the oil and gas reservoirs in the various hydrocarbon accumulation systems and their internal units.
