以全盆地为研究区域,通过野外露头、钻井岩芯单剖面、横剖面对比分析、有机质测试分析、沉积相分析,开展了太原组煤层形成环境及分布特征研究。研究结果表明:太原组煤层沉积环境主要是泥炭坪,但各地具体不同;在分布特征上,太原组煤层大面积分布在鄂尔多斯盆地东西两侧,中部主要为含煤泥岩,南北两侧分布很少。
Taking the whole basin as the research area, the formation environment and distribution characteristics of the coal seam in Taiyuan Formation were studied through field outcrops, single section of drilling core, comparative analysis of cross sections, organic matter test and analysis of sedimentary facies. The results show that: the sedimentary environment of Taiyuan Formation is mainly peat floor, but different from place to place; on the distributional characteristics, the coal seam of Taiyuan Formation is distributed widely on both east and west sides of Ordos Basin; the middle part is mainly coal-bearing mudstone with little distribution on both sides of north and south .
