摘　　要：近年来,坡移扇作为一种新型的岩性油藏类型越来越受到重视,完钻井效果较好,显示了坡移扇类型油藏较大的勘探潜力,但因其独特的发育位置导致其砂体识别难度大,缺少有效的识别技术。通过三维岩相建模方法,钻井与地震资料相结合,建立目的层段岩相模型,辅助地震进行坡移扇砂体识别,结合古地貌、地震相特征划分三角洲沉积相带。In recent years, more and more attention has been paid to the slope-shifting turbidite fan as a new type of lithology reservoir. The better drilled well results show that the slope-shifting turbidite fan reservoir has greater exploration potential, but for which it is still lack of the effective description techniques as its special development location which result to more difficult to be described. The lithofacies model of the target stratum is built up by 3D lithofacies modeling and combined the drilling data with seismic data, the slope-shifting turbidite fan body is identi- fied by seismic data, and the delta sedimentary facies belt is divided by combining the palaeogeomorphology with the seismic facies features.
