摘　　要：乌兰盖盆地是松辽外围中新生代火山岩盆地,盆地内工作程度很低。对于火山岩覆盖层下盆地的结构与地层展布特征尚不清楚,特别是对目标层(白垩系巴彦花群、侏罗系地层)的残留厚度、埋藏深度、分布范围等还缺乏了解,难以对目标层的油气前景做出科学的评价。在充分研究盆地岩石地层物性特征的基础上,根据重、磁、电各方法的优势,开展综合解释推断,从剖面、平面上分别解释推断了盆地白垩系巴彦花群、侏罗系地层的分布形态及构造格架,指出乌兰盖断陷盆地具有很好的找油气前景。Ulgoin basin is the cenozoic volcanic rock basin in the outside of Songliao.It is short of study in the basin.Structure and characteristics of stratigraphic distribution covered under the layers of volcanic basin are not clear,especially the thickness,depth,distribution of target stratum（Cretaceous Bayanhua Group and Jurassic morphology）is unknown.It is hard to assess scientifically the prospect of oil and gas in target layer.Based on an analysis of the physical characteristics of rock strata and taking advantage of the gravity,magnetic and electrical method,the authors carried out comprehensive interpretation and determined the distribution and tectonic framework of Cretaceous Bayanhua Group and Jurassic morphology.It is pointed out that the Ulgoin basin has a good prospect in the exploration for oil and gas resources.
