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。
侏囉紀地層為中國內陸沉積盆地油氣富集的主要時期地層。通過在前人的研究基礎上大量收集露頭資料以野外剖麵實測為重點，對山西不同地區侏囉紀地層不同組進行巖性、巖相、沉積特點及環境等分析，描述齣不同地區各箇組的沉積特點。劃定山西侏囉紀地層劃分為早侏囉永定莊組，中侏囉大同組、雲崗組、天池河組，缺失晚侏囉地層；對沉積相進行繫統分析，確定山西侏囉紀地層與鄂爾多斯盆地侏囉紀地層具有等時性，且空間上為鄂爾多斯盆地侏囉紀地層的邊緣沉積，油氣勘探前景不樂觀。

Jurassic formation is the main period of oil and gas enrichment strata sedimentary basins in mainland China. By a large collection of outcrop on the basis of forefathers' research, focusing on the field profile of the measured data of Shanxi in dif-ferent 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 analy-sis 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.
