邯邢煤田煤系沉积相及聚煤规律分析

以沉积学、岩石学理论和方法为指导,以野外露头、钻井岩心、测井曲线等资料为基础,宏观分析与微观研究相结合,并结合华北盆地其它地区的研究成果,分析探讨了邯邢煤田煤系沉积相类型和聚煤作用。结果表明:邯邢煤田煤系地层从中石炭世开始沉积到早二叠世,主要经历了潮坪、浅水三角洲沉积环境的演化过程,二叠纪浅水三角洲平原发育了全区稳定可采的2号煤层。

The analysis of sedimentary facies and coal accumulation of coal measure strata in Hanxing Coal field

This article is guided by the theory and method of sedimentology and petrology,based on the data of field outcrop,drilling core,logging curve and other data,and combination of macroscopic analysis and microcosmic study. Combining with the research results of other areas in North China Basin,the sedimentary facies type and coalite effect of coal in the coalfield have been discussed. The results show that the coal strata of Hanxing coal field deposites from the Carboniferous to the Early Permian,and experiences the evolution of the sedimentary environment in the tidal flat and shallow water delta. The shallow water delta of Permian develops the stable and recoverable 2 Coal seam.
