混沌学是当今非线性领域的一个重要分支, 用来刻划混沌系统动力学特征的最大Lyapunov指数, 反映了系统的动力学变为不可预测的尺度。本文初步探讨了利用最大Lyapunov指数进行油气检测的可行性, 开发出相应软件, 通过实例分析, 证明最大Lyapunov指数的曲线形态变化与油气分布基本吻合。

The chaos theory is an important branch of nonlinear science area. The maximum Lyapunov index,which is used to describe the dynamic characteristic of chaos system, can be regarded as the scale of system dynamics turning to unpredictability. In the paper, we preliminary approach the feasibility of hydrocarbon detection using the maximum Lyapunov index and develop the corresponding software. Practical example analysis proves that the shape of the maximum Lyapunov index curve is coincident on the whole with the hydrocarbon distribution.
