摘　　要：本文从有机质丰度、有机质类型及成熟度三方面对塔姆其萨依组烃源岩有机地球化学特征做了详细分析,其有效烃源岩厚度大(200-450m),有机质丰度高(有机碳平均1.29-2.88%),类型以Ⅱ型为主,部分Ⅲ和Ⅰ型,处于成熟-高成熟阶段(Ro主频1.0-1.9%),具有较好的生烃潜力。This paper makes a detailed analysis of the organic geochemical characteristics of the source rocks of the sayI formation in tamqi from the aspects of organic matter abundance,organic matter type and maturity.The effective source rocks are thick(200-450m),and the organic matter abundance is high(average organic carbon is 1.29-2.88%).The types are mainly of type II,some of type III and type I,which are in the stage of maturity to high maturity(RO dominant frequency is 1.0-1.9%)Good hydrocarbon generating potential.
