Fracture detection is similar to edge detection in image analysis. In this paper a thought of seismic fractal edge detection and calculation method are proposed based on IFS (Iterated Function System) image edge detection theory. Real seismic data processing results show that the drilling data have a high consistency with our prediction, and that this method is a valid fracture prediction technique, which is able to detect lateral undergrand fracture variation conveniently and reliably.
