摘要
在野外剖面观察、岩心分析、测井、测试等资料分析基础上,综合多方研究成果,对贝尔凹陷霍12井区的南屯组沉积体系类型,特征及演化进行了详细的分析。研究结果表明,区域内主要发育扇三角洲和深湖-半深湖沉积,浅湖和湖底扇发育较少,其演化过程主要分为南一段Ⅰ、Ⅱ、Ⅲ、Ⅳ四个砂组和南二段上下六个时期。
Based on observing outcrops, describing cores and analyzing the data of well logging and tests,comprehensive multi- research, a detailed analysis of depositional systems types, characteristics and evolution of Nantun formation in Huol2 3D area of Beier depression. The results show that, major development within the region fan delta and deep lake-semi-deep lake sediments, shallow lakes and lake fan developed less. The evolution process of South first stage is divided into Ⅰ,Ⅱ ,Ⅲ,Ⅳ four sand group and up and down of South second stage,a total of six stages.
