A Stratigraphic Modeling Method based on Borehole Data

The complexity of stratigraphic architecture makes the geological modeling over-reliance on labor, this means more timeconsuming and inefficiency. It is a difficult problem in using only borehole data in engineering survey for computerized automatic modeling to quickly establish the stratigraphic model. We joined connectivity criteria, as well as virtual drilling method, using an improved “layer-cake” method to create a stratigraphic model based on borehole data automatically. This method has the ability to deal with the formation lens, tip off, erosion and other phenomena of stratums effectively. We can make stratigraphy model based on the interpolated multi-layer of TIN data structure. This approach has been applied in engineering geological modeling of some regions in Nanjing, China.
