THE BOUNDARY ELEMENT METHOD IN EM-MWD
电磁随钻测量中的边界元法

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.
