山东山西组是煤和煤成气的重要富集层位。以综合地层学理论为核心，以岩石地层学、生物地层学、层序地层学等方法，将山东地区二叠系典型剖面淄博与鲁西（彭庄）、济阳坳陷山西组，进行对比研究，建立地层对比格架。经综合分析研究，得出山东地区山西组在纵向与横向上的变化趋势。造成这些变化的主要原因可能是晚石炭世鲁西是由东南向西北海侵。太原组上部灰岩的顶界，山西组泥岩的底部形成于突发性海侵向海退转化时。

Shanxi Formation is an important enrichment layer of coal and coal formed gas in Shandong province.Regarding the theory of integrative stratigraphy as the core,by using lithostratigraphy,bios-tratigraphy,sequence stratigraphy,strata in zibo and western Shandong(Pengzhuang)have been contras-ted with Shanxi formation in Jiyang depression,and the stratigraphic correlation relationship has been built.Through comprehensive analysis and study,lateral and longitudinal change trend of Shanxi forma-tion in Shandong province has been gained.The main reason for these changes may be the transgression di-rection is from southeast to northwest in western Shandong.The top of the upper part of limestone in Taiyuan formation and the bottom of mudstone in Shanxi formation were formed in the transformation pe-riod of sudden transgression to marine regression.
