陕南大河坝—观音庵地区铅锌矿激电测井应用效果

INDUCED POLARIZATION WELL LOGGING IN THE DAHEBA-GUANYINYAN LEAD-ZINC MINERALIZATION AREA

在金属矿产资源评价中,为配合大河坝—观音庵地区铅锌矿勘查,评价铅锌矿成矿有利地段,投入了以激电测井为主要,电阻率和自然电位测井为辅助手段地球物测理测井工作,结合激电、电阻率及自然电然测井曲线解释特征,划分钻孔岩性剖面,确定含矿层段,以期达到校正地质编录,划分钻孔地质剖面,准确划分矿层顶、底板位置的目的。

In assessment of the favorable portions of lead-zinc mineralization in the Daheba- Guanyinyan area, electric induced polarization well logging and other geophysical well logging methods of resistivity and self-potential logging were used for revise of the geological logging data, preeise division of lithological sections in boreholes and determination of the roof and foot walls of ore-bearing beds.
