Abstract：It has been shown that geological fractures have fractal characteristic.Fracture prediction of L section in Sichuan basin was made by doing fractal interpolation.The fractal interpolation is an approximating means for complicated space and describes detailedly the processed objects.In other words,a complicated graph of fractal characteristic can be plotted by doing interpolation along some known points.The operation of fractal interpolation is gradually performed in constructed iterativefunction system(IFS).The application of this method needs detailed fault interpretation in seismic section,which favours construction of a good fractal section.
