井中磁测三分量联合反演
Keywords: 井中磁测,三分量,联合反演,广义线性反演,长方体模型
Abstract:
？本文实现了井中磁测三分量联合反演,根据最小二乘原理建立了井中磁测三分量联合反演的目标函数,利用加阻尼因子的广义线性反演方法求解长方体模型几何参数与物性参数。通过5个理论模型反演结果的对比,得出三分量联合反演无论是对于井旁异常还是井底异常,无论是信息充分还是信息不充分,其反演结果都比单分量好。究其原因,是因为地磁场本身是一个矢量场,三分量联合反演充分利用了矢量场信息,提高了目标函数对未知参数的敏感度。将该方法用于新疆a矿区井中磁测资料的反演解释,较好得出井旁矿体的空间位置及下延情况。
