埕岛油田馆上段储集层属河流相沉积砂岩 ,砂体分布零散 ,连续性差 ,不存在大面积连通的活跃边底水。投入开发 3年来 ,已暴露出天然能量明显不足 ,饱和压力高 ,地饱压差小的矛盾 ,依靠注水补充能量开发势在必行。从埕岛油田整体构造入手 ,开展了陆相储层微型构造精细分类、微型构造与油气分布关系、油层顶面构造幅度与累油和含水关系研究 ,得出了规律性认识。为其它油田精细油藏描述、开发方案调整、剩余油分布研究提供了借鉴依据。图 2表 1参 4(王世艳摘 )
The upper reservoir section of Chengdao Oilfield is fluvial facies sedimentary sandstone with scattered sand bodies with poor continuity and no active edgewater with large area connectivity. In the past three years since it was put into development, the obvious contradiction between natural energy shortage and high saturation pressure has been exposed. It is imperative to rely on water injection to supplement energy development. Beginning with the overall structure of Chengdao Oilfield, the paper studies the relationship between micro-structure microfacies classification, micro-structure and oil-gas distribution in the terrestrial reservoirs. It provides references for the description of fine reservoirs in other oilfields, the adjustment of development plans and the distribution of remaining oil.
