Auto-construction algorithm of four-dimensional (4D) geological stratum on complex geological structure

Geological modeling is widely used in the fields of oil exploration and mineral resource exploitation. With the analysis of current constructing method of stratum, the 4D geological modeling method based on morphing algorithm was addressed. The faults spatial relation binary tree and spatial morphing fields were built, then the scatter points of stratum were restoring morphed to the original geological state and the 4D stratum of time t was constructed by rupture morphing the stratum's original geological net. Examples were given to demonstrate the validity of the algorithm. The algorithm can construct the 4D stratum automatically without interactive edit and is used in several fields such as oil forward modeling and underground water modeling.
