摘要

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。

Abstract

Guided by the theories of modern sedimentology and sequence stratigraphy, comprehensively using the outcrop, drilling, logging and seismic data and based on the boundary characteristics of the sequence system domains, the Upper Carboniferous-Permian strata of the study area were divided into three sedimentary sequences. The development information of the lowstand, transgressive and highstand system domains was ascertained, and the characteristics and distribution of seamarsh, river, delta, shore shallow-lake and beach dam these five sedimentary systems were indicated. At last, the favorable developing sequences of source rocks, reservoirs and covers and areas for exploration were suggested.
