The study of sequence stratigraphy and sedimentary system in Muglad Basin

Application of sequence stratigraphy theory, by levels of base level cycle sequence feature analysis, combined with core and log data, establish the sequence stratigraphic framework. The Cretaceous sedimentary strata are divided into six two sequences and 14 third-order sequences. In sequence stratigraphy based, combine well logging, seismic and core observation, and comprehensive analysis of each well rock type, color, bedding and other construction phase marks. Identify the Cretaceous strata have delta, meandering fluvial facies and braided river with three main facies. Detailed study of Cretaceous sedimentary characteristics, identify each sedimentary microfacies, sedimentary facies sequence established in the region.
