联合剖面法在寻找隐伏构造中的应用

摘要

Combined Profiling Method is an apparent resistivity measurement combined by two three-pole devices, whose feature is high resolution and obviousness. Therefore, it is one of the effective ways to look for upright low-resistance fracture zone. By measurement point by point along the measuring line, this method obtains ρSA、ρSB two sets of apparent resistivity parameter at the same time to detect the changes of geoelectric cross section in certain depth along the horizontal direction, then to locate the distribution of abnormal body in the plane.%联合剖面法是由两个三极装置联合组成的视电阻测量方法,具有分辨能力高、异常明显的特点,是寻找陡立良导脉状矿体或追索直立低阻破碎带的有效方法之一.该方法通过沿测线方向上的逐点测量,同时获取ρSA、ρSB两组视电阻率参数,以探测地下一定深度内地电断面沿水平方向的变化,确定异常体在平面上的分布.
