【摘要】 浅水三角洲是大规模岩性油气藏发育的基础,其形成的弥散状分布的砂体和频繁进退的湖平面是大规模岩性地层圈闭形成的有利条件。在岩心精细描述的基础上,利用测井、地震等地球物理手段,分析饶阳凹陷蠡县斜坡沙河街组沉积相类型及成因,建立了浅水三角洲的沉积模式,为在构造圈闭不发育的背景下寻找岩性、地层油气藏提供了勘探方向。更多还原

【Abstract】 Shallow-water delta is fundamental for development of large scale lithologic reservoirs.Dispersed distribution of sands and frequent transgression-regression of lake level are favorable conditions of forming lithologic-stratigraphic traps.Sedimentary facies and genesis are analyzed for the Shahejie formation in Lixian slope in Raoyang depression based on detailed core description in conjunction with logging and seismic methods.A depositional model of shallow-water delta has been built.This research provides exploration guide for finding lithologic and stratigraphic reservoirs in regions where structural traps were not developed.更多还原
