A Fast Method for Abstracting The Largest Lyapunov Exponent of Seismic Data
【摘要】 地震数据最大Lyapunov指数是油气储集层非线性研究的重要特征量。本文采用基于C-C法计算相空间重构参数的最大Lyapunov指数快速计算方法。此方法计算最大Lyapunov指数速度较快、计算量小、容易实现。克服时间延迟和嵌入维数需多次计算和确定的缺陷。
【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.
