摘　　要：侏罗纪地层为中国内陆沉积盆地油气富集的主要时期地层。通过在前人的研究基础上大量收集露头资料以野外剖面实测为重点,对山西不同地区侏罗纪地层不同组进行岩性、岩相、沉积特点及环境等分析,描述出不同地区各个组的沉积特点。划定山西侏罗纪地层划分为早侏罗永定庄组,中侏罗大同组、云岗组、天池河组,缺失晚侏罗地层;对沉积相进行系统分析,确定山西侏罗纪地层与鄂尔多斯盆地侏罗纪地层具有等时性,且空间上为鄂尔多斯盆地侏罗纪地层的边缘沉积,油气勘探前景不乐观。Jurassic formation is the main period of oil and gas enrichment strata sedimentary basins in China's Mainland. By a large collection of outcrop on the basis of forefathers＇ research,focusing on the field profile of the measured data of Shanxi in different areas in Jurassic strata of different lithology,lithofacies and sedimentary characteristics and environment analysis,describe the sedimentary characteristics of different areas of each group. Delimit the Jurassic strata are divided into early Jurassic Yongding village in Shanxi group,middle Jurassic Datong group,the Yungang,Tianchi river group,lack of late Jurassic strata,and analysis on the sedimentary facies system,Shanxi Jurassic strata and the Ordos basin,the Jurassic stratigraphic isochronous,and space on the edge of the Jurassic strata of Ordos basin deposition. Oil and gas exploration prospect is not optimistic.
