摘要
分析了地震非线性反演的混沌现象 ,并且从测井资料出发 ,以非线性动力学不动点理论及混沌控制理论为基础 ,提出了混沌控制反演方法 ,数值实验和应用实例表明 ,该方法能有效地控制非线性反演系统在反演选代过程中出现的混沌现象 ,得到较真实可靠的反演结果 .
The chaotic phenomenon in nonlinear inversion of seismic trace is analysed in detail. Borehole-restraint chaotic controlled seismic inversion method is developed on the basis of borehole data, nonlinear dynamic fixed-point theory and chaotic control theory. Numerical experiment and real example show that this method can effectively control chaotic phenomenon of nonlinear inversion system, which appears in inversion iteration, yielding reliable inversion results.
