摘要(Abstract)：

敖包塔油田西翼葡萄花油层资源潜力丰富,但油水分布复杂、成藏模式认识不清楚严重制约储量的有效动用.结合地震解释、测井、试油等资料,在构造特征及断裂系统划分、砂体类型及规模研究基础上,分析油水分布特点及控制因素,总结油气成藏条件及模式,根据断裂与砂体组合关系划分有利成藏模式.结果表明:受局部断块、岩性双重控制,全区无统一油水界面,平面"低油高水"、垂向"上水下油"现象频繁;葡萄花油层属于"下生上储、断层沟通、断层—岩性遮挡"成藏模式,油气来自下覆青一段源岩,反转期活动断裂为主要油源断裂;根据该区断裂、砂体组合特点,可细分出"下倾油源断裂沟通—上倾岩性尖灭"、"上倾反向断裂遮挡—侧向岩性尖灭"和"局部正向构造—高断块控藏"3类有利成藏模式.

关键词(KeyWords)：复杂油水分布;成藏控制因素;有利成藏模式;葡萄花油层;敖包塔油田西翼
