电阻率垂向电测深曲线定量解释已有系统的量板,因而比较成熟;而激发极化法的垂向电测深曲线的定量、半定量解释正处于逐步深入的阶段.目前野外已广泛运用η_κ测深曲线的转折点或趋近饱和值点处的AB/2极距估算矿体的顶部埋深.为了寻找曲线的更多特征点估算矿体的埋深,丰富定量解释的手段,我们对η_κ测深曲线的拐点进行了探讨.另外根据国外一些文献所见,利用改变装置的测量,如固定电源梯度测量,正交装置测深等也可以大致地估算矿体的中心埋深,顺便在此也作一简单介绍.
Vertical resistivity vertical sounding curve quantitative interpretation of the existing system of the plate, and thus more mature; and polarization of the vertical electric sounding curve of quantitative and semi-quantitative interpretation is in a step-by-step stage. At present the field has been extensive We use the AB / 2 pole pitch at the turning point of the η_κ sounding curve or approaching the saturation point to estimate the top burial depth of the orebody. In order to find more feature points of the curve to estimate the burial depth of the orebody and to enrich the means of quantitative interpretation, The inflection point of η_κ sounding curve is also discussed.In addition, according to some foreign literature, it is also possible to roughly estimate the depth of the center of the ore body by means of changing device measurements such as fixed power gradient measurement and orthogonal device sounding depth Here is a brief introduction.
