| 中文摘要: |
| 煤田地球物理测井是煤田勘探工作中重要技术手段，为达到最佳勘探效果，须充分结合当地的煤层地球物理特征。本文对以往使用电极系电阻率来解释煤层厚度和目前使用三侧向电阻率来解释煤层厚度进行了评述，对其影响煤层定厚的精度等不足进行了概括，提出三侧向电流曲线来代替三侧向电阻率曲线进行煤层的定厚解释，此曲线继承了三侧向电阻率曲线的优点，同时也克服了它的缺点。 |
| 英文摘要: |
| Coalfield geophysical logging is an important technical means in coalfield exploration. In order to achieve the best exploration effect, it is necessary to fully integrate the local coal seam geophysical characteristics. In this paper, the previous use of resistivity of electrode system and the current use of trilateral resistivity are reviewed to explain the thickness of coal seam, the shortages of its influence on the accuracy of coal seam thickness determination are summarized. Therefore, a trilateral current curve is proposed to replace the trilateral resistivity curve in the interpretation of coal seam thickness.This curve inherits the advantages of the trilateral resistivity curve and overcomes its shortages. It’s hoped to attract the attention of the industry. |
