摘　　要：张店-白秋地区地处南阳凹陷北部斜坡内带,是油气运移的主要指向区。区内发育不同期次、不同走向的断层,形成大小不等、形态各异的复杂断鼻、断块圈闭;牛三门生油次凹核桃园组暗色泥岩是该区主力烃源岩,砂层和活动断层是该区油气运移优势通道,砂体与烃源岩的配置关系、不同沉积微相砂体的物性差异以及断层的分布是该区油气运移和富集的主要控制因素。Situated in northern slope zone of Nanyang depression, Zhangdian-Baiqiu area is considered to be the main hydrocarbon migration area where different faults with different strikings have been developed under different stages, forming various complicated faulted-nose and faulted-block traps with different sizes. Dark mudstone of Hetaoyuan formation in Niusanmen sag is believed to be the main source rock. Sand layers and active faults are favorable for hydrocarbon migration. The relationship between sand bodies and source rocks, physical property differences of different sedimentary microfacies and faults distribution are main controlling factors for hydrocarbon migration and enrichment.
