Abstract:

Nonlinear inversion in the reservoir prediction is a very important field of geophysics.On the base of nonlinear methods,such as artificial neural network,fractal and fractal dimension etc.,the authors expound that, as a method of nonlinear inversion,Seimpar Inversion could carry out wave impedance inversion without using convolution equation, and also inverse logging parameter byseismic records under the logging constrained.This method of inversion could resolve complex geological problems which are hardly to be solved by routine inversion, and it is applied well in practice.

Key words: limestone cave, organic reef, the numerical simulation of seismic wave field, snapshot of seismic wave field
