| 摘 要： | 焦家金矿带3 000 m勘查科研深钻使用多种测井方法,原位获取了钻孔岩石的各种物理化学参数,实现了设计预定的数据采集目标,取得了丰富的初步解译研究成果。通过交会图等技术分析了不同岩石的测井响应特征;通过常规识别法和主成分分析方法相结合,有效的识别了断裂带;通过阵列声波测井了解了岩石机械特性并估算了地应力参数;通过井温测量实现了井温梯度的计算。激电测井显示,低阻高极化为深部矿化体主要异常特征;依据极化率曲线整体幅值及形态分析认为2 485~3 122 m为矿化较为集中部位。

| Abstract: | A variety of logging methods have been carried out in deep drilling at the depth of 3000m for exploration and scientific research in Jiaojia belt. A lot Of valuable physical and chemical parameters of rock infomlation have been obtained in normal position. Combining with various logging methods, lithology has been identified, the characteristics of logging response have been analyzed, the fissures and cracking zones have been identified, ground stress parameters has been estimated, the geothermal gradient has been calculated, and main locations of the gold ore bodies have been determined. |
