根据网毯式成藏体系结构的研究思路和研究模式,以准噶尔盆地白垩系油气成藏体系为例,研究网毯式成藏体系结构与油气成藏的关系。经研究分析可得,准噶尔盆地的油气成藏体系可划分为3个不同的层次,包括以岩性地层油气藏为主的毯状仓储层、以构造油气藏为主油气聚网层和油源通道网层。从总体上看,油气分布的特点是沿层发散、顺断汇聚,但是准噶尔盆地网毯式成藏体系结构中主要的控制因素是分布的稳定性和物性,其中包括厚度较大的仓储层和沟通仓储的断裂。本文以准噶尔盆地为例主要分析了网毯式成藏体系结构与油气成藏特征。
According to the research ideas and research patterns of the bed-forming reservoir architecture, taking the Cretaceous hydrocarbon accumulation system in the Junggar Basin as an example, the relationship between the structure of the bed-forming reservoir system and hydrocarbon accumulation is studied. After research and analysis, it can be concluded that the hydrocarbon accumulation system in Junggar Basin can be divided into three different levels, including the carpet reservoir mainly consisting of lithologic reservoirs, the oil-gas accumulation net reservoir and oil source Channel network layer. Generally speaking, the distribution of oil and gas is characterized by divergence and consequent convergence along the layers. However, the main controlling factors in the networked formation system of the Junggar Basin are the distribution stability and physical properties, including the thicker reservoir layers and Broken communication warehousing. Taking Junggar Basin as an example, this paper mainly analyzes the characteristics of the net-blanket reservoir forming system and hydrocarbon accumulation.
