摘要
对于有耗分层媒质中的垂直透层天线,建立了Hallen积分方程分析法的一般理论以及求取地面电场和电压的计算方法.作为应用实例,给出了地下3层媒质中钻杆天线上的电流积分方程,并对典型的地质参数进行了数值计算.所得结果和结论,与已知的理论结果和实验规律吻合。
This paper is concerned with the theory of the underground penetrating antennas.The general method to set up the Hallen-type integral epuations for the dirll rod natenna and the formulas to compute field strength and voltages on the ground surface are presented.As a typical application,the Hallen integral eqnations for the drilling antenna used in the MWD systems are given in the nudeground three-layered media.The numerical computations using typical data for the model are carried out.Some beneficial results are obtained,which are coincide with the regularly from other theory and experiments.
