摘　　要：针对石南31井区含油气层地质时代归属与地层划分认识上的问题,在对古生物、岩心和地球物理资料系统分析基础上,在层序地层学和沉积体系的分析原理指导下,通过砂层组的对比、地震层序界面识别和追踪、石南31井区含油气层地质时代属白垩纪,为早白垩世早期清水河期沉积,其层位高于白垩系底砾岩。油藏类型为砂体上倾尖灭型岩性油气藏。In view of disputable adscription of geological era and petroliferous formation classification of Shinan-31 Wellblock in Junggar basin, the systematic analyses of existing data from paleontology, core sample and geophysical prospecting are conducted. The geologic era of the petroliferous strata is dated as Qingshuihe stage of Early Cretaceous, which is higher than the basal conglomerate of Cretaceous in horizon, through the correlation of sand layers and the identification and tracing of the seismic sequence boundary by means of sequence stratigraphy and sedimentary system theory. The reservoir type of Shinan-31 Wellblock belongs to the lithologic reservoir with upward pinchout sands.
