以鄂尔多斯盆地东北部太原组-山西组含煤地层为研究对象,通过大量钻井岩芯观察及测井曲线识别性,分析煤层的发育特征及环境对煤层的控制作用。太原组T1小层顶部和山西组S1-3小层顶部煤层发育好,厚度大,连片性好,具工业开采价值。潮坪-泻湖中的泥炭沼泽和三角洲平原洼地中的泥炭沼泽都是聚煤的有利场所,其中潮坪-泻湖中的泥炭沼泽是煤层发育的最有利场所。
Taking the Taiyuan Formation-Shanxi Formation coal-bearing formation in the northeastern Ordos Basin as the research object, through the observation of a large number of drilling cores and the identifiability of well logs, the development characteristics of the coal seam and the control of the coal seam by the environment are analyzed. The top of T1 in Taiyuan Formation and the top of S1-3 in Shanxi Formation are well developed, with large thickness and good continuity, and have industrial exploitation value. The tidal flat - the peat bog in the lagoon and the peat bog in the delta plain depressions are all favorable places for coal accumulation, and the tidal flat - the peat bog in the lagoon is the most favorable site for coal seam development.
