摘　　要：本文以高分辨率地震资料为基础 ,应用测井、钻井等资料 ,从沉积微相分析入手 ,建立了以河道砂体、河口坝砂体为主的地质及地震响应模型 ,并根据地震反射波组特征、地震反演的阻抗值及其他地震属性参数 ,确定了研究区的砂体变化及其分布规律 ,总结出一套针对薄互层特点的岩性圈闭识别技术。本文方法在大庆长垣以西古龙和他拉哈西地区的实际应用中取得了明显的效果。Based on high-resolution seismic data , using logging,drilling and seismic dat a and starting from analysis of sedimentary mini-facies,the paper built up geo logic and seismic response model mainly for channel sand body and sand body in r iver mouth bar;according to the characteristics of seismic reflected wave group, impedance values from seismic inversion and other seismic attributes and paramet ers,the regularity of sand body changes and distribution in studied area have be en defined.We summarized identification techniques for lithologic traps characte rized thin and interbedded layer and achieved better results in practical applic ation in Gulong and Talaha areas,west of Daqing Great Anticline.
