磁化率测井是直接在钻孔中测量岩矿石磁化率沿井壁的连续变化,从而比较直观地划出钻孔井壁岩矿石的磁性剖面,较准确地确定磁性层的厚度和深度,配合地面和井中磁测,对磁异常作出快速评价. 我队测井组从1979年开始使用重庆地质仪器厂生产的JCL-Ⅱ型磁化率测井仪,在莱芜铁矿区开展了生产试验工作.从几年来的工作中体会到,磁化率测井与通常的磁秤法测定标本相比,其特点是:方法简单,成本低,效率高,资料连续性好,是值得积极推广的一种测井方法.
Magnetic susceptibility logging is the direct measurement of rock core magnetic susceptibility along the borehole wall continuous changes in the borehole, so as to more intuitively draw the magnetic profile of rock borehole rock ore, more accurately determine the thickness and depth of the magnetic layer, with the ground And well magnetic measurements to make a quick assessment of magnetic anomaly.My team logging team began to use the JCL-Ⅱ magnetic susceptibility logging tool produced by Chongqing Geological Instrument Factory from 1979 to carry out the production test work in Laiwu Iron Mining Area. Years of work experience, magnetic susceptibility logging and the usual magnetic scale determination of specimens compared to its features are: the method is simple, low cost, high efficiency, data continuity is good, it is worth promoting a well logging method.
