摘要: 东营凹陷是东部陆相断陷湖盆一典型代表,其北部陡坡带特殊的构造背景,使沉积地层中各种成因的砂砾岩扇体极为发育,并成为勘探的重要目标.近几年,针对北部陡坡带6种成因的砂砾岩扇体进行了详细的地质地震相模式研究,确立了扇体在同层沉积的平面分布、纵横向演化及剖面组合模式,并针对扇体的复杂性,总结了识别与描述扇体的层位标定、横向追踪、综合描述和预测技术及勘探方法,提高了该带的勘探效果,也为类似陆相断陷湖盆砂砾岩扇体勘探提供了成功的经验.

Abstract: Dongying Depression is a typical continental rift basin in eastern China.Against the background of the special structure of the northern steep slope,many kinds of sandy-conglomeratic fans have been formed in the strata,which become the major exploration target now.On the basis of integrated studies of geologic and seismic faces about six kinds of those fans,the paper presents the areal distribution in the same formation,evolution in horizontal or vertical direction and combined mode of sections.On account of the fans complexity,author summarized the exploration technique and methods of identifying,tracing,describing and predicting the horizons representing fans, which have lead to exploration effect in this area and provided successful experience for the exploration of this kind of fan.

Key words: Dongying Depression, steep slope, fan, reservoir, exploration technique
