| 摘 要： | 本文从动力学系统原理出发，论述了混沌理论中的李指数法，并从地震剖面上提取李指数，并应用李指数来区分和识别储集层的岩性变化特征和含油气性。计算和应用研究表明，李指数随着相空间维数的增加容易趋于稳定值，这就使它预测地震序列横向变化的可靠性增大，这正是李指数预测岩性和含油气性的一个优越性。成功地应用实例表明，混沌识别技术是岩性储集层的一种有效识别技术，并具有广阔的应用前景。

| Abstract: | Based on the nonlinear dynamic principle, the paper describes method of Lyapunov exponent in chaos theory. The Lyapunov exponent is computed from seismic section. Lithological information and distribution of oil and gas can be predicted by using Lyapunov exponent. It provides us an effective technique of recognizing the lithological reservoir. The demenstration of some practical examples shows that technique of chaos theory recognition is of wide application. |
