摘　　要：白庙气田位于东濮凹陷东部兰聊断裂带下降盘中段,为兰聊断裂和杜寨断层共同控制的一个继承性半背斜。应用变换构造理论,识别出白庙气田发育有3种类型变换构造,变换构造类型以调节构造为主,传递构造少见且规模较小。受变换构造控制,该地区主要发育粗粒的冲积扇、扇三角洲和浊积扇沉积。变换构造产生地层、构造及岩性圈闭,为油气的聚集提供了场所,影响着该区油气的分布。Baimiao gas field lies in the middle part of the downthrow side of Lanliao fault in the east of Dongpu depression and is an inherited half-anticline controlled by Lanliao fracture and Duzhai fault. Three types of transition structures are identified in Baimiao gas field. The transition structures are dominated by accommodation structures, and the transfer structure is seldom seen and small in scale. As controlled by the transition structure, this area mainly developed coarse fluvial fan, fan delta and turbidite fan sedimentation. The transition structure had generated stratigraphic, structural and lithologic traps which had provided places for hydrocarbon accumulation and affected oil and gas distribution.
