Abstract:With the application of f uzzy mathematics,geological structure (depressions and uplifts) are determined first, then each alternative point for the velocity curve is taken as a f uzzy point (f uzzy set) in four dimensional space by rule of thumb in manual velocity picking; after integrated judgement, the brightness of each fuzzy point is determined and the selected points art connected into a line to complete the autornatic velocity picking, The method can simulate precisely and feasibly the process of manual velocity picking。The program of automatic velocity picking using this algorithm has resulted in satisfactory stack sections on TIMAP computer.
