摘要: 作者通过对大量地表和钻井剖面砂岩薄片的系统观察研究,认为本区北部的库车拗陷属前陆盆地;南部的阿瓦提-满加尔拗陷为克拉通内拗陷盆地。在盆地类型分析的基础上,结合本区油气勘探的成果,对盆地油气藏分布模式和油气资源勘探远景进行了分析、预测。Abstract: In the light of systematic study of a large number of sandstone thin-sections from surface exposure and wells, the authors considered that the Kuqa depression in the north ofthe Tarim basin was a foreland basin,and the Awat-Mannaer depression was an intra cratonic downwarped basin. On the basis of analysis of basinal types,combining the result ofoil/gas exploration in the area,the distribution pattern of hydrocarbon accumulation andhydrocarbon exploration prospect were analysed and predicted.
