摘　　要：基于大量地质与地球物理资料,分析了车排子地区白垩系底部不整合结构特征、输导通道类型及输导作用。车排子地区白垩系底部不整合主要为2层结构,不整合面之上岩石及半风化岩石发育,风化黏土层不发育。研究区具有双运移通道、单运移通道、封堵型3种通道类型,双运移通道类型与油气高显示程度、高运移指数有良好对应关系,此类型输导通道发育区的构造高部位是油气的有利聚集区。The unconformity structure,translocation types channel types and translocation effect of Cretaceous bottom formation in Chepaizi is analyzed based on a number of geology and geophysical data. The unconformity of Cretaceous bottom formation in Chepaizi mainly consists of 2 structures. Rock and semi- weathered rock are developed and weathered clay is less developed in the upper part of unconformity surface. Dual- migration,uni- migration and plugging channels are mainly developed in the study area. The dual- migration channel is well correlated with high hydrocarbon show and high migration index. The high part in the area with well- developed dual- migration channels is the favorable hydrocarbon accumulation area.
