通过对库拜煤田阿艾村和音西煤矿侏罗系煤系地层观察、实测露头岩性、沉积构造、特征标志、关键界面等方法,划分沉积亚相、沉积相,按垂向组合特征划分体系域单元。在下侏罗统塔里奇克组至中侏罗统克孜勒努尔组划分出5个沉积层序,从中寻找煤层发育有利层位,总结聚煤规律性。对最大水泛面作为沉积层序关键参照界面依据进行讨论。 Through the observation of the Jurassic coal-bearing strata in the Aai Village and Yinxi Coal Mine in the Kuibu coal field, the outcrop lithology, sedimentary structure, characteristic sign, key interface and other methods are used to divide the sedimentary subfacies and sedimentary facies, Domain unit. In the Lower Jurassic Tarim Basin to Middle Jurassic Kizil Nur group, five sedimentary sequences are divided, looking for favorable layers for coal seam development and summarizing the regularity of coal accumulation. Discussed the basis of the largest flooding surface as the key reference interface of sedimentary sequence.
