摘　　要：研究了中原地区奥陶系风化壳的储集性能、成岩演化史、沉积相等特征，指出中新生代构造演化史、风化壳的层位、构造应力作用等是影响本区储集层发育的关键因素，东濮凹陷南部、济源、成武、黄口等凹陷风化壳储层发育，具有良好的油气勘探前景。Based on the formation features in Zhongyuan region, this paper makes a systematic analysis of the hydrocarbon saving capacity,diagenetic evolution, sedimentary facies etc. of the Ordovician weathering crust reservoir.It is indicated that the key factors that govern the Ordovician reservoir in the area are tectonic evolution, sedimentary facies and structural stress. The fractured crust weathering reservoirs are developed in the south of Dengpu Depression,J iyuan, Chengwu and Huangkou Depression, they are favorable hydrocarbon exploration regions, having broad petroleum exploration prospects.
