Abstract
The present invention relates to a method for identification of geology lithological difference which includes: obtaining seismic amplitude data of a geology object to be detected; using a seismic amplitude value of each grid point as the initial value of chaos nonlinear iteration equation and then to iterate by the equation, and recording an iteration convergence rate of each grid point when the iteration reaches a stable state; and depicting the lithological difference of the geology object to be detected by the difference of the convergence rate of each grid point. The solution of the present invention can identify the geology lithological difference more sensitively.
