摘要
利用井间电磁波CT技术可以对地下岩溶、破碎带等问题进行精细探查。本文通过构建岩溶区域模型,利用数值模拟手段对岩溶区进行电磁波CT透视模拟,讨论电磁波在岩溶发育区的衰减及响应特征。结合杭州某地实施孔间电磁波透视成像,对岩溶发育区进行解释,并与钻孔实际揭露地质资料相对比,结果表明电磁波CT对探测岩溶发育区效果良好。
The use of wellhead electromagnetic wave CT technology can be underground Karst, broken belt and other issues for fine exploration. In this paper, the Karst area model is used to simulate the electromagnetic wave CT of Karst area by numerical simulation method, and the attenuation and response characteristics of electromagnetic wave in Karst development area are discussed. The results show that the method has a good effect on the detection of Karst development area, and the results show that the method is effective in detecting the Karst area.
