周口盆地是华北地台南缘一个大型的中新生代沉积盆地，谭庄－沈丘凹陷是盆地中部中、新生代两期断陷叠合的次级构造单元，燕山期以来至少经历了6次差异升降运动。这些构造运动对地层的保存、有机质的热演化、油气的生成、运移、聚集起了控制作用。本文采用地震剖面、钻井分层、粘土矿物、镜质体反射率、声波时差5种方法进行剥蚀厚度的恢复，试图再现盆地发育史历史，以对油气藏的形成条件研究有所脾益。 The Zhoukou basin is a large Mesozoic-Cenozoic sedimentary basin on the southern margin of North China. The Tanzhuang-Shenqiu depression is a sub-unit of superimposed Mesozoic-Cenozoic fault faulting in the central part of the basin. It experienced at least 6 differences since the Yanshan Period Move up and down. These tectonic movements played a controlling role in the preservation of strata, the thermal evolution of organic matter, the formation, migration and accumulation of hydrocarbons. In this paper, five methods of seismic profile, drilling stratification, clay mineral, vitrinite reflectance and acoustic jet lag are used to recover the thickness of the eroded layer, trying to reproduce the history of the basin development history to study the forming conditions of the reservoirs.
