【摘要】 随着东营凹陷北部陡坡带王庄—宁海地区亿吨级稠油藏的发现,砂砾岩扇体成藏类型的隐蔽油气藏勘探已经成为现阶段的油气勘探的重点目标和储量增长点之一。利用现代沉积学、测井学和地震勘探等手段,通过对王庄地区砂砾岩扇体及其油气成藏特征研究后认为:王庄地区在下第三纪以形成Es3+4段的较高水动力能砂砾岩扇体(冲击扇、扇三角洲、近岸水下扇)沉积储集体为主,其中扇三角洲砂砾岩体是本区最主要的油气储集体;油藏类型以岩性—地层型圈闭为主,油气的聚集和分布均受沉积相的控制,油藏具有复杂多变的特点。更多还原

【Abstract】 With the discovery of a hundred million tons’ heavy oil reservoir in Wangzhuang area of north steep slope in Dongying depression,glutenite fan subtle heavy-oil reservoir has become one of the key aims and mounting reserves.With the methods of sediment and log and seism,through the research of glutenite fan and its reservoir characteristics in Wangzhuang area,this article concludes that the upper kinetic energy Es3+4 glutenite fan sediment reservoir(alluvial fan,fan delta,nearshore subaqueous fan) was mainly formed in Wangzhuang during early-tertiary,and the fan delta glutenite body is the main reservoir in Wangzhuang area.The lithologic-stratigraphic trap is the main style of reservoir.The oil massing and distributing was dominated by sediment face,and the reservoir was complex and protean.更多还原
