在勘探磁铁矿床或含强磁性矿物的多金属矿床等深部磁性矿床的过程中,通常采用井中三分量磁测量方法对其空间赋存状态做出判断,利用垂直分量曲线的“正负开口”特性发现井底盲矿体,指导钻孔钻进,避免漏矿事件的发生;根据测量的磁场三分量数据及磁化率测井数据来发现矿产位置,确定矿体形状、规模、产状等。举出实例,叙述其应用效果,并且对所举实例进行详细分析,阐述解释推断方法的具体应用。
In the process of exploration of deep magnetic deposits such as magnetite deposits or polymetallic deposits containing ferromagnetic minerals, the three-component magnetic measurement method in the well is usually used to judge the spatial occurrence state of the deposits. The vertical and horizontal component of the “ ”Features Blind orebodies found at the bottom of the hole to guide the drilling and drilling to avoid the occurrence of ore leakage events. Based on the measured three-component magnetic field data and magnetic susceptibility log data to find the location of the mineral, determine the shape, size, . Give an example, narrate its application effect, and give a detailed analysis of the examples, explain the specific application of the inference method.
