摘　　要：以马头营凸起唐71×2断块馆二段4~6砂组河道砂体为研究对象,针对窄河道控制下单砂体厚度薄(单砂体厚度小于4m),横向变化快(单河道宽度小于100m),传统地震相分析法难以对窄薄砂体进行预测的问题,在利用钻井资料和测井资料综合分析沉积相的基础上,总结河道砂体在地震上的响应特征,运用地震地层切片属性技术,精细刻画了河道砂体的平面展布。实践证实:预测结果与钻井实测结果吻合度较高,该方法预测窄薄河道砂体可信度高。The channel sand body of the 4th~6th sand formation of the second member of Guan Formation in Tang 71×2 fault block in Matouying Uplift is taken as the research object,aiming at the problems of thin single sand body thickness(thickness of single sand body is less than 4 m)and rapid lateral change(width of single channel is less than 100m)controlled by narrow channel,traditional seismic facies analysis method is difficult to predict narrow and thin sand body,on the basis of comprehensive analysis of sedimentary facies using drilling and logging data,summarizing the response characteristics of the channel sand body,using seismic stratum slice attribute technology,the plane distribution of channel sand body was finely characterized。It is proved by practice that the predicted results are in good agreement with the measured drilling results,indicating that this method has high reliability in predicting narrow and thin channel sand bodies。
