| Abstract: | In the low SNR and complex geologic condition, the factors affect seismic imaging effect are energy equilibrium, SNR of data, bin dimension fold and velocity model. The authors analyze the factors and expound the solution in seismic data processing, include the application and limitation of this solution. |
