| 摘 要： | 简要地介绍了宽带约束反演的基本实现思路，并着重介绍应用人工神经网络方法将约束反演得到的波阻抗转换成储层物性参数的方法。在储层参数计算中，应用了ＲＢＦＮ网络求取预测函烽，并对预测函数进行显著性估计。该方法在塔里木盆地塔北牙哈下第三系储层分析中应用效果良好。

| Abstract: | At first, how to make broad constrained inversion is briefed. And then emphasized is a method of computing reservoir nature parameters from acoustic impedance inversion by using ANN. A predictive function is calculated with RBFN(Radial Basis Function Network), and the significance of the function is estimated. Field applications to the reservoir analysis of Paleogene of Yaha, Tabei in Tarim Basin show that the method mentioned above is quite well. |
