摘　　要：意4井构造上位于查干凹陷西部次凹北部断块群。目的层为苏一段、巴二段和巴一段。用有机地球化学实验分析方法,从有机质丰度、有机质类型、有机质成熟度等3个方面对意4井泥岩进行了分析和评价,从而对进一步勘探查干凹陷提供依据。实验分析认为巴音戈壁组二段烃源岩有机质丰度高,母质类型为过度型,主要为Ⅰ型、ⅡA型,类脂含量丰富,有机质热演化程度不高,未进入大量生油阶段,为中-好的烃源岩。Yi 4 well is located in the Chagan sag Western concave North fault block group.Target layer is in Su 1, Ba 2 and Ba 1 section.This research takes the dark color mudstone of the Yi 4 well as the dissection object,and takes advantage of many parameters such as organic matter abundance,the type and maturity of organic matter to describe quantitively or qualitatively the hydrocarbon-generating potential characteristics of the source rock,in order to provide the basis for further exploration in Chagan sag.Results indicate that the source rock's organic matter abundance of the Bay ingebi Formation 2 is the highest,which organic types as excessive type,mainly for type I,IIA type,and lipid content is rich,but organic matter maturity is not high,without access to a large number of oil phase,belongs to the middle or good source rock.
