【Abstract】 The largest Lyapunov exponent of seismic data is an important characteristic of the nonlinear research of hydrocarbon reservoirs.A new method based on utilizing the C-C method to estimate parameters in the phase space reconstructions for calculating the largest Lyapunov exponent was presented in this paper.This new algorithm is easily carried out,and has high efficiency and accuracy.It overcomes the flaw that the delay time and the embedding dimension need to calculate many times.更多还原
