广域电磁法H-HZ方式波数域的一次场特征
Wave-Number Domain Features of Primary Field of H -Hz Arrangement Wide Field Electromagnetic Method
摘要
Abstract
In the 2. 5D forward and inverse modeling of controlled source electromagnetic method (CSEM), inverse Fourier transform is unavoidable, whether the results are right or wrong is decided by the wave-numbers. In order to research the key point, the wave-number domain primary field of H - Hz wide field electromagnetic method is calculated, the corresponding features are analyzed at the same time. The conclusions show us that both in space domain and in wave-number domain, the characteristics of magnetic curves are alike. Besides, large wave-number leads to very smaller magnetic value. These only can waste the time, but have no use for improving the precision of the results. A group wave-numbers are selected which is reasonable. The computation of the Chave's algorithm is superior to the Anderson's algorithm.关键词
