Seismic Facies Identification and Sedimentary Facies Analysis in Upper Cretaceous Madama Formation, Termit Basin, Niger
摘要
Abstract
On the basis of logging data and seismic data, the Madama Formation of Upper Cretaceous in Termit Basin in Niger was interpretated as a third-order sequence, which includes a lowstand system tract(LST), a transpressive system tract(TST) and a highstand system tract(HST). In this study, four major seismic facies (progradational seismic facies, channel filling seismic facies, parallel to subparallel reflection seismic facies and clutter reflection seismic facies) and one sedimentary facies(braided river delta) have been identified. The LST mainly developed the braided river delta front, the HST mainly developed the braided river delta plain, and the sedimentary evolution of Madama Formation is a regressive process as a whole.关键词
