| 摘 要： | 宽带约束反演是用井中测得的波阻抗作为初始模型和约束条件，应用随机反演理论，与最优化计算技术相结合蜓人间外推，从而获得了最佳宽带波阻抗剖面。本文展示了实际应用的例子，证明宽带约束反演是一种精度高，稳定性强，收敛快的反演方法，具有广阔的应用前景。

| Abstract: | In broadband constrained inversion,the wave impedance data derived from logging data areused as initial model and constrained condition to obtain optimizatial broadband wavc impcdancesection by using stochastic inversion and optimization mdthod.practical exanpels are given,which show that this mcthod will find wide application because ofits high auuracy,good stability and fast convcrgcnce velocity. |
