K法克服电阻率测量中的似非而是现象

THE ANOMALOUS PHENOMENA IN RESISTIVITY MEASUREMENT OVERCAME BY K METHOD

低阻导电基底断面上水平地层的电阻率测量中出现的似非而是现象,其物理实质可用反射系数来作定性解释;文中由此提出了用电反射系数代替视电阻率作为研究参数,从而达到克服似非而是现象的目的。野外实测资料的处理结果更有力地说明了这种解释方法的可行性。

The physical essence of the anomalous phenomena in recording the resistivity of horizontal strata on cross section of low-resistance conducting basement may be given a qualitative interpretation with reflection coefficient; this paper thus suggests an idea of taking electrical reflection coefficient instead of apparent resistivity as study parameter to overcome the anomalous phenomena. The result of calculations from field exploration data demonstrates further the reliability of the interpretation method.
