The Outline of Methodology and Application of Log Sedimentology

There has been a theoretical and practical base for sorting out and develo-ping the log sedimentology. Firstly, as seismofacies, log facies has been de-veloped to be a generalized concept of sedimentary facies, which can be translatedinto lithofacies and of which there exist various presentations accepted bygeologists and reservoir engineers. To be synthesized with facies and seismo-facies approach, the process of log facies study is basically divided into threephases: the single profile facies analysis, the cross-profile facies correlationand the surface profile correlation. The results from log sedimentology studyis of significance to regional exploration and field production. However, itshows that log sedimentology is a very multidisciplinary and multiorganiza-tional technique.
