【摘要】 为了达到极浅海埕岛油田高速高效的开发效果 ,从埕岛油田整体构造入手 ,进行了精细构造解释 ,并根据埕岛油田定向井多的特点 ,对砂体进行了平面和纵向归位 ,从而落实了砂体顶面微构造的准确形态 .并统计了各种微构造与含油性的关系 .开展了微构造类型与累油含水关系研究 .结果表明 :构造高部位和正向微构造含油性好 ,累油高 ,含水上升慢 ;负向微构造含油性差 ,累油低 ,含水上升快 .最终确定了有利的剩余油分布地区 ,包括正向微构造和断层夹持形成的微构造等 ,并为埕岛油田下步挖潜指出了方向更多还原

【Abstract】 Based on the whole structure of Chengdao Oilfield, the interpretation of its fine structures is made. The lateral and vertical positions of the sand-bodies in the oilfield and the accurate morphology of the top surface microstructures of the sand-bodies are determined by means of a large number of directional wells in Chengdao Oilfield. The relationships between the types of microstructures and the cumulative production and water cut are studied. It is shown that, the high positions of the structure and positive microstructures have good oil reserving capacity, cumulative oil production is higher and water cut increases at a lower rate; negative microstructures have worse oil reserving capacity, cumulative oil production is lower and water cut increases at a higher rate. The favorable remaining oil distribution regions are determined, which provides the guidance for the further development of Chengdao Oilfield.更多还原
