运用层序地层学和沉积体系分析相结合的方法，对潮水盆地侏罗系进行综合沉积学研究，识别出各级层序界面特征，将侏罗系划分为２个构造层序、３个一级层序、４个二级层序、８个三级层序；发现各级层序地层单元对富煤带的控制因素是古气候条件、构造运动和与之密切相关的沉积环境，但对不同级别的层序地层单元控制因素具有主次之分。沉积体系分析结果表明，潮水盆地侏罗系的富煤单元主要发育于冲积扇沉积体系和扇三角洲沉积体系。
Using the combination of sequence stratigraphy and sedimentary system analysis, the comprehensive sedimentology of the Jurassic in the tidal basin was studied, the characteristics of sequence boundaries at various levels were identified, and the Jurassic was divided into two structural sequences and three 4 secondary sequences and 8 tertiary sequences. It is found that the controlling factors of the coal strata in the sequence stratigraphic units are palaeoclimatic conditions, tectonic movement and closely related sedimentary environment, Different levels of stratigraphic unit control factors have primary and secondary points. Sedimentary system analysis results show that the Jurassic coal-rich units in the tidal basin mainly develop in alluvial fan depositional systems and fan delta depositional systems.
