高密度电阻率法具有数据采集密集、生产效率高、观测精度高和分辨率高的特点,已经成为常规物探方法之一,本文介绍了四种高密度电阻率法装置的工作方式,并对同一测线的四种高密度电阻率法装置勘探结果进行了比较,结果表明:在该地电条件及在相同的剖面长度下,温纳装置较其它装置具有更好的勘探效果,而偶极装置更适用于垂向电性变化大的地质情况。
The high-density resistivity method has the characteristics of dense data acquisition, high production efficiency, high observation accuracy and high resolution, and has become one of the conventional geophysical methods. This paper introduces the working methods of four high-density resistivity method devices, The results of four kinds of high-density resistivity measuring devices are compared. The results show that, under the conditions of the geoelectric field and the same cross-sectional length, the Wenna device has a better exploration effect than other devices, and the dipole device More suitable for vertical electrical changes in the geological conditions.
