摘要(Abstract)：

本文就线圈系金属支柱对电磁波测井的影响进行了理论考察。文中确定了数学模型,提出了计算方法。计算结果表明,线圈系采用金属支柱是可行的,金属支柱的存在不影响电磁波测井中常用的相位差和幅度比的测量值。文中也提出了设计金属支柱线圈系的一系列原则。
: The effect of coil array with metal stanchion on electromagnetic logging is studied theoretically.A numerical model is set and cadculation method is put forward.Calculation result shows that coil array with metal stanchion is feasible and the existence of metal stanchion has no influence on measured val-ues of commonly used phase differential and ratio of amplitude in electrmegnetic logging. A series of principals of designing coil array with metal stanchion is put forward.
