摘要

准噶尔盆地是多期构造挤压环境下演化形成的大型陆内叠合盆地,其盆地类型既有前陆盆地,也有陆内凹陷,其中,前陆盆地主要分布在造山带逆冲断裂前缘,陆内凹陷主要分布于盆地内陆区。基于前人的研究成果,结合在准噶尔盆地油气勘探开发实践中取得的新认识和对准噶尔盆地周缘盆—山耦合区带地质剖面及盆地不同时期沉积地层特征的分析,认为该盆地自二叠纪以来发育了3期前陆盆地,这3期前陆盆地及与其相关坳陷的组合和叠加是形成准噶尔盆地丰富油气资源和多样化成藏模式的主要原因。

Abstract

The Junggar basin is regarded as a large-scale inland composite basin under the multi phase evolutions of compressed tectonic environment. The basin types are both foreland basin and intracontinental basin. Foreland basin is mainly located in the frontier of the thrust faulting of orogenic belt while the intracontinental basin is situated in the inland area of the basin. Based on the previous researches, combined with the further understanding of the present oil gas exploration, the exploitation of the Junggar basin, the analysis of the sedimental strata characteristics in different stages and the mountains profiles on the margin of the Junngar basin, it is considered that there are three period foreland basins formed since the Permain in Junggar basin. The composition and superposition of those three period foreland basins are the main reasons for the rich oil and gas resources and diversified reservoir models of the Junggar basin.
