层状各向异性介质中任意取向电偶源的海洋电磁响应
Keywords: 各向异性,一维,海洋可控源电磁,汉克尔变换
Abstract:
？从麦克斯韦方程组出发,利用双重傅里叶变换和矢量势函数,详细推导出了层状各向异性介质中任意取向电偶源的电磁场计算公式,利用汉克尔数值滤波方法计算得到电磁场,并验证了算法的正确性和精度.有限长电偶源不能作为电偶极子源计算其电磁场响应,尤其是在收发距较小的情况下,可以采用积分法或者将有限长电偶源剖分成足够多的电偶极子源计算其电磁响应后累加得到有限长电偶源的电磁响应.针对海底油气模型,分析了覆盖层和油气层的垂向电阻率在不同姿态发射源下电磁场的变化情况,发现覆盖层和油气层的垂向电阻率对水平电场有很大影响,且轴向装置要比赤道装置受覆盖层和油气层垂向电阻率的影响大.
