摘　　要：以沉积学、层序地层学理论和方法为指导,以野外实测剖面资料为基础,结合野外露头、钻井岩心、测井资料,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,探讨了邯邢煤田煤系层序特征,在此基础上,以层序为单位编制岩相古地理图,结果表明:邯邢煤田煤系划分为四个层序,结合盆地分析,层序类型、海泛面及沉积体系域发育特征,以层序为单元分析岩相古地理演化,邯邢煤田煤系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。Under the guidance of sedimentology, sequence stratigraphy theories and methods, taking the field measured sections as basis, combined with field outcrops, drilling cores, well logging data macroscopic analysis and microscopic study, as well as studied results of other areas in the North China Basin, have discussed the Handan-Xingtai coalfield coal measures sequential features. On this basis, taking the sequence as element compiled lithofacies-paleogeographical map. The result has shown that the coal measures in the coalfield can be partitioned into four sequences, combined with basin analysis, sequence type, marine-flooding surface and depositional systems tracts development features, taking the sequence as element has analyzed lithofacies and paleogeographical evolution. From the middle Carboniferous sedimentation start to the early Permian, the coal measures in the Handan-Xingtai coalfield have experienced a tidal flat to shallow water delta sedimentary environment evolution process.
