| 中文摘要: |
| 为了解岩（矿）石磁化率测定法（磁化率仪）在反映钻孔中岩层磁性变化规律方面的效果，对同一钻孔分别运用岩（矿）石磁化率测定法和井中磁化率测量法进行了对比分析研究。结果表明，岩（矿）石磁化率仪测定法具有成本低、速度快、灵敏度高等特点，可以作为井中磁化率测量的一部分，起到井中磁化率测量在准确确定矿层厚度、位置、矿层品位等方面的作用，避免测井设备的笨重所带来的麻烦，特别是能够弥补井中磁化率测量在有套管存在井段的严重数据不足之缺陷。 |

| In order to make clear of effect of magnetism change law of strata of drill hole reflected by susceptibility meter measurement comparative research is carried out on measurements of susceptibility of rock (ore) sample from core and that measured in drill hole from which the sample is collected. The result shows that susceptibility meter measurement is characteristic of low cost, quick measure and high sensibility and it can be served as a part of susceptibility measurement playing role in accurately determining thickness, location of ore layers and grade of the ore layers so as to prevent movement of the heavy well measurement equipments, especially remedying severe scarce data of susceptibility measurement data of the casing intervals. |
