摘　　要：前侏罗系是吐哈盆地重要的油气资源接替层系。库木凸起上发育有上石炭统、二叠系桃东沟群、下二叠统艾丁湖组三套烃源岩,油源断裂发育,圈闭众多,类型好,资源量丰富。吐哈盆地侏罗系、二叠-三叠系和石炭系三大含油气系统在此交汇,是前侏罗系油气运移的有利指向区,是一个多层系含油的巨型复式油气富集带,凸起的北缘已发现油气田,南缘的构造带同样具备良好的油气成藏条件,是近期盆地区域勘探的重点领域。The pre-Jurassic is the important sequence for replacement of petroleum resources in Tuha basin. There are three sets of source rocks developed in Kumu swell. They are the Upper Carboniferous, the Taodonggou group of Permian and the Aydingkol Lake formation of Lower Permian, in which faults and traps are well developed with good types of traps and abundant resources. Three major oil-bearing systems such as Jurassic, Permian-Triassic and Carboniferous exist at this area, becoming a favorable target area for oil migratiou and a giant and multi-sequence oil-bearing zone. The oil-gas field has been found in northern margin of Kumu swell. The structural belts of the southern margin have the same conditions for oil and gas accumulation. They could be the major exploration regions in the near future.
