Impact of 3D Seismic Technologies on Sedimentology Study
Progress of 3D seismic technologies has played a vital role in the developments of sedimentology in terms of analytical methodology and concepts. High-density and high-resolution 3D seismic data can be used to reconstruct 3D views of sedimentary paleo-evironment by direct imaging of depositional elements and can also be used to analyze sedimentary paleo-evironment evolution in 3D detail by mapping facies variability at a specific geologic time by slicing though it. And such data connected with well logging data can be used for predictions of rock properties distribution to delineate sedimentologic heterogeneity. High resolution of 3D seismic data mapping can also be used to image the geometry of diagenesis front to a resolution of a few meters over thousands of square kilometers, which is a new approach to the study of diagenesis process in basin scale. The potential for future developments in this field is considerable. Relative methods and examples of such Studies on the aspects mentioned above are presented.
