摘　　要：鄂尔多斯盆地西南部演武地区含油层系主要存在于侏罗系延安组地层中,油藏分布受构造控制作用明显,勘探难度较大。在对该区延安组砂岩的电成像测井特征及古水流分析基础之上,对该区砂体的展布进行了预测;利用电成像资料上泥岩倾角及倾向数据,对该区构造进行了分析,结合区域上储层发育特征,指出了有利于石油聚集的区带;在对该地区声电成像测井反映出的裂缝及井眼垮塌方位数据分析之上,论述了研究区地层应力特征。The main oil layers exist in the Jurassic Yanan Formation in Yanwu area in the southwest of the Ordos basin. Distribution of the reservoir is obviously controlled by the tectonic, and the exploration is more difficult. Distribution of the sand body is predicted on the basis of the electrical imaging characteristics of sand rock and paleocurrent analysis in this area. The tectonics in this area is analyzed with log data of the inclination and tendency of mud rock. Combined with the features of the reservoir, given is the favorable zone of oil accumulation. Based on analysis of acoustical and electrical imaging log data about cracks and collapsed borehole, discussed are the formation stress characteristics of the above area.
