【摘要】 埕东凸起北坡是济阳坳陷河道砂体油气勘探的主阵地之一。以该区馆陶组为研究对象,对在精细构造解释、河道砂体描述和含油气判识3个方面应用比较成功的相干体分析、水平切片分析、三维可视化分析、地震与测井联合反演、地震属性分析、瞬时频率以及振幅值统计等地球物理技术进行了系统总结,同时对埕东凸起北坡河道砂体进行了分类评价,共描述砂体104个,预测Ⅰ类砂体56个,Ⅱ类砂体24个。探讨了埕东凸起北坡馆陶组河道砂体描述中应用地球物理技术应注意的问题。更多还原

【Abstract】 Northern slope of Chengdong Uplift is one of the main positions of channel sandbodies in Jiangyang petroleum exploration. The successful techniques used fined structural interpretation, channel sandbody description and hydrocarbon recognition in Guantao Formation exploration such as coherent data,horizontal slice,3D visualization,joint inversion of seismic and well log,seismic attribute, instantaneous frequency and amplitude statistic, were analyzed systematically. And the channel sandbodies in northern slope of Chengdong Uplift were classified and evaluated with these techniques. One hundred and four sandbodies were described, and fifty-six type I and twenty-four type Ⅱ sandbodies were predicted. And the key points that should be noticed while using geophysical techniques in channel sandbodies description were discussed.更多还原
