| 摘 要： | 接收线圈分布参数对早期瞬变电磁信号影响严重,导致信号的有效采样时间起始点后延,丢失浅层探测信息。本文比较了过渡过程影响下的视电阻率误差,并描绘视电阻率误差随接收装置半径变化曲线。结果表明,在相同有效接收面积的前提下,选择不同半径的接收装置对视电阻率计算会带来不同程度的影响,解决工程实际中接收线圈最佳半径设计问题。

| Abstract: | Distributed parameters of the receiver coil greatly affect the early transient electromagnetic（TEM）signals,which can delay the start point of signal＇s effective sampling time and lose shallow exploration information.This paper compares the apparent resistivity deviation under the influence of transient process and describes the curve of apparent resistivity deviation with the change of receiver coil radius.The results show that,under the same effective receiving area,different radius of receiver coils can have different impact on the calculation of the apparent resistivity.This paper provides a practical way to design the optimal size of receiver coil radius. |
