摘要
本文应用层序地层学的理论和技术,结合露头、钻井岩心和测井资料,分析了研究区内主要的沉积相,并建立等时地层格架。在此基础上,分析研究区的聚煤规律及富煤单元的形成条件。研究发现研究区内主要可采2#、3#、10#煤层都发育于海侵体系域的晚期的泥炭沼泽环境下,其它不可采煤层发育于高水位体系域早期的沼泽环境。
In this paper,according sequence stratigraphy of theories and technologies,combineing with outcrop,drill core and logging data,I analysis of the study area of the sedimentary facies,and establish isochronous stratigraphic framework.On this basis,I analysis of thecoal accumulating pattern and the formation conditions of rich coal unit in this study area.we can find out 2#、3#and 10# coal seam formed in peat swamp environment of the late transgressive system tract.And other non-production coal seam was formed in peat swamp environment of the early high-stand system tract.
