该文在现代沉积学和层序地层学理论的指导下 ,综合利用露头、钻井、测井和地震资料 ,以层序体系域边界特征为划分依据 ,将研究区上石炭统至二叠系划分成 3个沉积层序 ,并确定了低位、水进和高位体系域的发育情况 ,明确了滨海沼泽、河流、三角洲、滨浅湖和滩坝等 5种沉积体系的特征和展布 ,最后指出了有利的生储盖层发育层段和有利勘探地区 Under the guidance of modern sedimentology and sequence stratigraphy theory, this paper comprehensively utilizes outcrop, drilling, well logging and seismic data, basing on the boundary features of sequence system tract, divides the Upper Carboniferous to Permian Into three sedimentary sequences and determined the development of low, water-in and highstand system tract, clarified the characteristics and distribution of five sedimentary systems such as coastal marsh, river, delta, shore-shallow lake and beach dam, and finally pointed out Favorable facies and reservoir developmental strata and favorable exploration areas
