| 摘 要： | 多参数约束反演是用井中测得的波阻抗作为约束条件，进行宽带约束反演，再将宽带约束反演的结果与测井反演得到的岩性和孔隙率模型等相结合进行空间外推，从而获得多种参数剖面。本文展示了实际应用的例子，证明了多参数的约束反演是一种精度高，稳定性强的反演方法，具有广阔物应用前景。

| Abstract: | In multiparameter constrained inversion, the wave impedance data derived from logging data are used as constraint condition to make band constrained inversion, then many parameter sections can be produced by doing extrapolation using both the result of band constrained inversion and the models of lithology and porosity which are taken from logging data inversion.Practical examples are given, which show that this method will find wide application because of its high accuracy and good stability. |
