摘　　要：为高效直接地寻找祁连小水沟地区铁多金属矿区井底、井旁的隐伏矿体,通过采用井中三分磁测法,研究对比三分磁测测井资料ΔZ、ΔH′曲线及ΔT′矢量的变化规律寻找隐伏矿体.达到了科学减少钻孔数量,指导钻孔施工方向,较准确预测钻孔四周隐伏矿体,有效提高见矿率的效果.For efficient and direct prospecting for concealed orebodies beneath and near the exploratory well of iron polymetallic orefield in Xiaoshuigou area,Qinghai Province,the method of three-component magnetic survey in borehole is applied to study the logging data ofΔZ andΔH′curves and change rules ofΔT′vector.It can scientifically reduce the borehole number,guide the drilling direction,accurately predict the concealed orebody around the drilling hole,and effectively improve the percentage of ore discovery.
