摘要:

山东山西组是煤及煤成气重要的富集层位,随着能源开采的需要,亟需进一步厘清覆盖区山西组内部地层特征;笔者以综合地层学理论为核心,利用沉积学、岩石地层学、生物地层学等方法结合钻井、测井等资料,将山东地区二叠系典型区域鲁西南、济阳坳陷山西组,进行地层特征对比研究,建立地层对比关系;经研究发现鲁西南与济阳坳陷山西组岩性总体特征相似,厚度略有变化,济阳坳陷单层煤层较鲁西南薄;孢粉组合对比表明,济阳坳陷裸子植物较鲁西南有所增加,反映济阳坳陷气候较鲁西南干旱。

Shanxi Formation is an important enrichment horizon of coal and coal-formed gas in Shandong; as the needs of the energy exploitation, the internal stratigraphy characteristics are cleared further in Shanxi Formation; The theory of integrative stratigraphy is treated as the core by the author, the Sedimentology, Lithostratigraphy, Biostratigraphy combine the drilling, logging and so on are selected to contrast the strata in Southwest and Jiyang Depression of the covered area in Shandong, and the stratigraphic correlation relationship is builded; The research shows that the lithology characteristics are similar fundamentally, the thickness has a little change, the single coal in Jiyang Depression is more thinner than it in Southwest; the contrast on the sporopollen combination shows that the gymnosperm in Jiyang Depression is more than it in Southwest, so the climate in Jiyang Depression is more droughty in Southwest.
