本文主要讨论了如何利用测井参数求取地层波阻抗的问题。文中利用钻井的实际测井资料,着重探讨了根据声波、密度、电阻率曲线求取波阻抗的可能性,并通过计算结果分别构制了一些相关曲线,导出了相应的计算公式,同时还作了一些简要的对比。

The key point of this paper is the extraction of the wave impedance of the strata by use of the well parameters from the data of the acoustic logging,the density logging and the resistivity logging. Some correlation curves were constructed from the results calculated. The corresponding equations for the calculation were given.
