An Adaptive Inverse-Distance Weighting Interpolation Method Considering Spatial Differentiation in 3D Geological Modeling

The inverse-distance weighting interpolation is widely used in 3D geological modeling and directly affects the accuracy of models. With development “smart” or “intelligent” geology, classical cannot meet accuracy, reliability, efficiency requirements large-scale models these fields. Although improved can basically it at same time. In response to limitations, adaptive method based on attribute spatial differentiation feature adaptation was proposed. This takes into account attributes improve considers first-order neighborhood selection strategy adaptively above modeling. proposed applied an area eastern China, results method, compared interpolation, suggest that problems encountered be solved with method. provide effective support for smart geology.
