利用沉积学及层序地层学方法，通过对章丘煤田主要构造单元单井沉积相、层序地层分析，将章丘煤田石炭二叠纪含煤岩系的本溪组、太原组、山西组划分为1个一级盆地层序、2个二级构造层序、3个三级层序。在层序内部识别最大湖泛面或与之相当的沉积转换面，划分体系域，并重点对三级层序的划分进行研究。研究认为：三级层序Ⅰ发育高水位体系域和海侵体系域，主要由潮坪沉积体系、障壁-泻湖沉积体系和碳酸盐台地沉积体系组成；层序Ⅱ发育海侵体系域和高水位体系域，主要由潮坪体系、滨外台地体系和障壁-泻湖沉积体系组成；层序Ⅲ中低水位体系域、海侵体系域、高水位体系域都有较好发育，主要由浅水曲流河三角洲沉积体系组成。

In this article,by using sedimentology and sequence stratigraphy method,through analysis on sedimentary facies and sequence stratigraphy of single well in major tectonic units in Zhangqiu coalfield, Benxi formation,Taiyuan formation and Shanxi formation of Carboniferous-Permian coal-bearing strata can be divided into one first-order basin sequence,two second-order tectonic sequences and three third-order sequences.Within the sequences,maximum flooding surface deposition or equivalent conversion surface have been distinguished,system fields have been divided,and the division of three orders sequences have been studied emphasisly.It is regarded that:third-order sequence Ⅰdeveloped high level water sys-tem field and sea intrusion system field,and are mainly composed of tidal sedimentary system,barrier-la-goon sedimentary system and carbonate platform sedimentary system;sequence Ⅱ developed sea intrusive system field and high water level system field,and are mainly composed of tidal system,offshore platform system and barrier-lagoon sedimentary system.Sequence Ⅲ developed medium-low water level system, sea intrusive system field and high water level system,and are mainly composed of shallow meandering riv-er delta sedimentary system.
