中文摘要：

从构造形态、有效源岩区、断裂密集带、断层—砂体—地层匹配和超压等方面,分析王府凹陷扶余油层油气富集规律。研究结果表明：王府凹陷扶余油层构造形态控制流体势,进而控制油气整体运移方向和主要分布区域;有效源岩区范围制约油气分布范围;断裂密集带对油气运移具有横向遮挡、侧向输导双重作用;断层走向与倾向、砂体展布方向和地层倾向的组合方式决定能否形成圈闭;青山口组烃源岩层超压影响油气向下运移距离;王府凹陷青山口组烃源岩大约在埋深超过1 200 m之后所残留的烃类基本达到饱和并向外排烃,埋深超过1 200 m的烃源岩范围为有效源岩;王府凹陷扶余油层双51、双35和双50等井一线以北至凹陷中心的区域有利于形成断层-岩性油气藏。

英文摘要：

Combining various aspects such as tectonic character, effective source rock zone, intensively faulted zone, fault—sand—stratum matching and overpressure, the hydrocarbon enrichment laws of Fuyu Formation in Wangfu Depression was analyzed. The results show that the tectonic character of Fuyu Formation in Wangfu Depression controls the fluid potential, and also controls the migration direction and the distribution regions of hydrocarbon. The effective source rock area controls the distribution range of hydrocarbon. Intensively faulted zone has transverse sealing and lateral fluid conduction function in hydrocarbon migration. The combination of fault, sand body and stratum, which has different trends, tendencies and distributions, controls the formation of traps. The overpressure of source rock in Qingshankou Formation affects the downward migration distance of hydrocarbon. While the buried depth of source rocks in Wangfu Depression is more than 1 200 m, the residual hydrocarbon is saturated and hydrocarbon starts expelling from source rocks. The source rocks buried more than 1 200 m are effective hydrocarbon source rocks. The region from the line of Shuang 51, Shuang 35 and Shuang 50 wells to the center of depression is favorable exploration areas of fault-lithological reservoir in Fuyu Formation of Wangfu Depression.
