电测深法各装置形式之探测效果研究

Study of Detecting Effect on Different Resistivity Sounding Devices

选取2-5层水平层状地电模型,采用不同的电阻率和深度组合,正演了四极、三极、偶极、五极纵轴和微分五种装置的电测深曲线.结果发现,对同一水平层状地电模型,五种装置的测深曲线无任何实质性差异,亦即它们的探测效果不可能有实质性差异。这一结论与有些学者所持的微分测深装置具有独特探测效果一说强烈冲突,谨希望能引起业内同仁的注意与探讨。

This paper presents 2-5 level layer models.The resistivity curves of quadrupole,three-pole,dipole,five-pole lengthways axis and differential deices are formulated through the combination of resistivity and depth.The result shows that there is no essential difference among the five sets on the same level of the layer model.It means that there is no difference in detecting effect.The result is opposite to some experts＇ view that the differential sounding device has a special detecting effect,so it hopes that the result may provide a further study for the experts.
