摘要
塔木察格盆地为中新生代陆相沉积盆地，地层自下而上划分为基底、铜钵庙组、南屯组、大磨拐河组、伊敏组和青元岗组以及第三系和第四系。通过对层序界面的识别，建立起地层层序框架，塔南凹陷从铜钵庙组到大磨拐河组共划分为4个三级层序。同时对层序类型的划分、平面展布情况以及控制因素进行了细致分析。总结出4种层序模式和每种模式控制下的油藏类型。在实际生产中，综合每个构造带的构造特征部署的探井证实了层序模式的研究对于该区的油气勘探提供了有利指导。
Tamtsag Sag is Mesozoic-Cenozoic terrestrial deposit basin. Stratigraphic composition from bottom to top is as following： basement, Tongbomiao Formation, Nantun Formation, Damoguaihe Formation, Yimin Formation, Qingyuangang Formation, Tertiary and Quaternary Systems. Through the identification to the sequence interfaces, the sequence stratigraphic frame is established： there are 4 three-grade sequences classified in South Tamtsag Sag from Tongbomiao to Damoguaihe Formations. At the same time, the division of sequence types and their plat distribution and controlling factors are analyzed in detail. Four types of sequence models and the oil reservoir kinds controlled by each model are summarized. In practice, the studies of the above sequence models are verified by the exploration wells arranged by integrating the structural characteristics of each tectonic belt. All the achievements obtained above have provided favorable guidance for the petroleum exploration of the region.
