【摘要】 在系统总结东营凹陷北部陡坡带砂砾岩扇体沉积类型、分布规律、组合特征的基础上,综合运用钻井、地质与地震资料,建立了砂砾岩扇体的地震识别模式;通过对砂砾岩扇体的地震地质特征的总结,指出不同地区、不同时期的湖盆边缘可以形成不同类型的砂砾岩扇体;根据扇体的地震识别模式可以在地震剖面上直接寻找各类扇体,并判定其成因及储层物性。分析有利含油气部位和油藏类型,以此来指导勘探部署工作。更多还原

【Abstract】 Seismic identifying model is established for glutenite fan in the north actic region of Dongying sag based on sedimentation type, distribution law, assemblage feature, and drilling, geologic and seismic data. It is pointed out that different glutenite fan might be formed on lake basin edge in different area and period. With seismic profile, we can find various fans, judge their genesis and petrophysical properties, and recognize favorable structure and reservoir type to guide oil and gas exploration.更多还原
