High resolution sequence stratigraphy And micro-facies of fluvial deposits, Upper Guantao formaiton, Chengdao Field

摘要

By the application of high resolution sequence stratigraphy, upper Gutao Formation, the Main oil-bearing Formation in Chendao oil field is divided into two subsequence. It has three parasequence groups and 21 Parasequences in upper subsequence. We leave done the facies analysis for each parasequence, Microfacies includes channel bar, point bar, crevasse-splay, inter-channel, and flood plain.
