| Abstract: | 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. |

| Keywords: | nonlinear inversion impedance fixed-point chaotic control |
