摘要： 库米什盆地位于南天山东段。该区断裂发育,多具左旋性质,分析了可能的断层组合关系。盆地构造演化可以划分为4个阶段。分析认为中生代盆地具伸展断陷盆地”特征,而新生代盆地演化为挤压走滑型山间盆地”。库米什盆地具有良好的勘探前景:发育两套主要烃源岩、具良好的储盖组合和多种圈闭类型。对勘探前景分析后认为,近期勘探方向应以沉积厚、埋藏深、靠盆中”的硝尔-杨布拉克坳陷为主，该坳陷内基底最深的杨布拉克凹陷为最有利远景区。

Abstract: Kumux basin is located in eastern sector of South Tianshan Mountains, characterized by developed faulting with sinistral property.The fault assemblage relations are analyzed. There are four stages in structural evolution of this basin. It was an extensional and faulted basin inMesozoic, and then developed into an intermountain basin with compressed strike-slip attribute in Cenozoic. Study shows that Kumux basin is ofbright exploration prospecting for its two sets of major source rocks, good reservoir-seal assemblage and multi-trap types. It is considered fromanalysis that the recent petroleum exploration should pay more attention to Xiaoer-Y ang Bulak depression with thick sediments, deep buriedsource rocks and near the center of the basin. Yang Bulak sag located at the deepest within the depression is the most favorable potential areafor petroleum exploration.
