【Abstract】 This paper presents a modified version of the Frazer’s simulated annealing method for calculating interval velocities. The synthetic seismograms are forward calculated using a convolution model, and the error’s energy is defined using the L1 norm. Theoretical modeling and practical seismic processing show that such method is effective and the resultant interval velocities are reliable. In addition to the rapidity and robustness, the method has another distinguishing feature of reducing the ambiguity for objectivc functions.更多还原
