摘要(Abstract)：

利用野外观察描述和断裂输导与油气藏分布之间关系,对成藏与分布的控制作用及断裂输导特征进行了研究,认为断裂内部可分为破碎带和诱导裂缝带2个部分,伴生和派生裂缝及碎裂岩的连通孔隙是其主要输导通道。同一条断裂在不同演化阶段输导油气能力不同,不同断裂在相同活动时期输导能力也不同。断裂的空间分布控制着油气的空间分布,源岩大量排烃期后的断裂活动时期即为油气的大规模运聚时期,断裂活动开启程度的差异控制着油气富集程度的差异。
By means of field observation,description and the relation between fracture transformation and petroleum distribution, the controlling action and transformation characteristics of reservoir-forming and distribution are studied.It is thought that there are two parts within a fracture:broken belt and induced fracture belt,the connected pores and fissures among accessory and derived fractures and broken rocks are main transforming channel.In different evolution stage,even the same fracture has different ability to transform petroleum and furthermore even in the same active period, different fractures also possesses different this kind of ability.The space distribution of those fractures controls the space distribution of oil and gas;the active period of the fractures after the large-amount hydrocarbon discharge stage is the time of large-size petroleum migration and enrichment,the opened degree variation of a fracture action controls one of petroleum enrichment degree.
