【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油气勘探的重点目标和储量增长点之一。文中利用现代沉积学、测井学和地震勘探等手段,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沙三、沙四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 one hundred million tons heavy oil reservoirs in Wangzhuang-Ninghai Area of north steep slope of Dongying Depression, the glutenite fan subtle oil reservoir has become one of the important exploration targets and the increasing points of oil and gas reserves.Through the research on the glutenite fan body and its hydrocarbon accumulation characteristics in Wangzhuang Area and the use of modern sedimentology, well logging and seismic exploration, it is considered that Es3+4 sandstone and glutenite sedimentary fan bodies with high hydropower energy such as alluvial fan, fan delta, inshore subaqueous fan are the main sedimentary reservoirs in Wangzhuang Area during Eogene, in which the fan delta glutenite body is the most major reservoir in this area.The main reservoir type is lithological-stratigraphic reservoir.The hydrocarbon accumulation and distribution are controlled by the sedimentary facies.The hydrocarbon reservoir are very complicated and proteus.更多还原
