| 摘 要： | 针对AMT法数据的特点,介绍了提高其纵向分辨率、去除噪声干扰、压制静态效应的常用处理方法及其特点;就咸淡水共存区AMT资料处理技术以及矿化度评价工作中数学模型建立问题进行了探讨,介绍了两种建立孔隙地层地下水矿化度数学模型的方法,并给出了相应的应用实例;同时说明,不同物探手段和不同反演方法都会造成获得地层电阻率值的差异性,在同一工区利用同一矿化度评价数学模型要注意工作方法和反演方法的一致性。

| Abstract: | In the light of the characteristics of AMT data,this paper deals with the commonly used data processing methods for improving the vertical resolution,removing noise and suppressing the static effect as well as their characteristics.According to the quality of the raw data and the geological problems to be solved,we should choose different processing and inversion methods as well as their combinations in practice so as to get true and reliable formation resistivity values.Two means are also described in this... |
