【摘要】 利用油气地震勘探成果和露头的岩性资料 ,对库车坳陷地震层序进行划分 ,初步认为第三系膏盐层和三叠 -侏罗系煤层及泥岩是分布比较稳定的区域性软弱层 ,构成了区域内的主要滑脱面。将库车坳陷划分 6个构造带 ,对库车坳陷的构造样式进行归纳总结 ,并结合典型实例 ,采用平衡地质剖面技术对重要剖面进行地质平衡解译 ,使库车坳陷地质结构更加清晰。结合该区油气成藏的地质条件 ,划分出若干油气聚集带 ,对各油气聚集带进行分别评价更多还原

【Abstract】 The seismic sequence of Kuqa depression is subdivided according to oil- gas seismic exploration results and lithological data of the outcrops.Tertiary gypsium beds and Triassic- Jurassic coal and mudstones are priliminarily determined to be regional soft layers with relatively stable distribution,which make up the main detachement surface of the region.Six structural belts are subdivided in the Kuqa depression.The in- duction of structural styles,and geological balanced interpretation of the key sections by using balanced geo- logical section technology in couple with the typical examples help to geta more clear geological framework of the Kuqa depression.All oil- gas accumulatin belts are subdivided and evaluated according to geological condi- tions.更多还原
