Abstract:

The theorectical and practical approaches of continental sequence stratigraphy are becoming one of the hot spots faced by the communities of sedimentologists and petroleum geologists. The key aspects of continental sequence stratigrapgy are referred to as the geometry and filling dynamics of continental strata. Although numerous studies have been accomplished and a number of models have been presented, no well-documented models have been constructed yet. The applications of computer modeling to continental sequence stratigraphy permit us to more exactly examine the sequence formation, facies association, major controls and effects on stratial geometry, sedimentary facies and seismic sequences (sequence sets). The further studies will be conducted to genetically explore the formation and evolution of continental stratigraphic sequences, with the emphasis on seismic stratigraphy, logging stratigraphy, biostratigraphy and well data, and to make the prediction of the prospects through the static and dynamic analysis of the source-reservoir-seal associations and the events within the oil-bearing systems, respectively.
