摘　　要：在系统描述葡萄花油田北部鞍部地区构造特征和断裂体系的基础上,分析了烃源岩大量排烃期与构造形成时期的匹配关系、砂体分布、地层压力和断层封闭性对研究区成藏的控制作用。研究结果表明:烃源岩大量排烃期和构造形成时期良好匹配,地层压力低势区和在成藏时期断块边界断层侧向开启是成藏的有利条件,构造和砂体分布则是成藏的主要控制因素。研究区成藏条件较好,可作为有利扩边潜力区。The tectonic features and fault characteristics of the saddle in northern Putaohua oilfield are de- scribed, and the controlling factors on hydrocarbon accumulation, including the matching of forming time of structural traps with hydrocarbon expulsion, distribution of sand body, formation pressure and fault sealing, are analyzed in this paper. The results indicate that oil generation and expulsion matched well with structural traps, lower formation pressure and the fault which is parallel migration path of oil are advantages of hydrocarbon accu- mulation in saddle of northern Putaohua oilfield. The hydrocarbon accumulation is controlled by tectonic features and distribution of sand body. It is the potential extension area for its good conditions of hydrocarbon accumulation.
