摘要(Abstract)：

葡北油田东部地区葡萄花油层油水分布较为复杂.通过分析试油试采、油水井生产及地质静态等资料,研究油水在平面和垂向上分布规律.结果表明:油水分布在平面上具有分带特征,以东西两个区带为主要富油区;在垂向上具有分异特征,以葡Ⅰ3—葡Ⅰ5小层为主要富油区.油水分布的主控因素包括:构造单元控制油水的分布规律,表现为研究区在平面上油水具有分带特征;在三角洲前缘相的沉积背景下,分流河道沉积砂岩层是葡萄花油层的优质储层;以北北西向为主的断层与葡萄花油层水下河道沉积砂体相互匹配,且断块式与反向正断层式的匹配样式对控油最有利.该研究结果为葡北油田后续勘探开发提供地质依据.

关键词(KeyWords)：油水分布;分布规律;主控因素;葡萄花油层;葡北油田
