电磁随钻测量中的边界元法
THE BOUNDARY ELEMENT METHOD IN EM-MWD
-
摘要: 电磁场线性边界元法被成功地用于求解半空间有损媒质中的非对称电偶极激励。它将为电磁随钻测量的工程问题提供一种简单实用的算法。本文对低频极限情况下的两种模型的计算结果都与实验和稳流场公式的结果进行了比较。

Abstract: The linear boundary element method for electromagnetic fields is ta-ken to deal with the exitation of a non-symmetrical electric dipole in a lossv half space. A simple and practical algorithm is offered to the electromagnetic measu-rement while drilling (EM-MWD). The calculations on two models under the low frequency limits arc compared with the experiments and the results calculated with the theory of srationary currenr fields. -
