Abstract

In order to improve the accuracy of groundwater detection, the forward problem of NMR response in three-dimensional is discussed in this paper. The three-dimensional magnetic field equations and boundary conditions in frequency domain with the loop source are derived by Maxwell's equations and then the functional expression is given. The finite element method is applied to calculate the forward modeling. Numerical simulation shows that the excitation pulse moment is help to increase the detecting depth. Shallow aquifer resistivity has more influence on the initial signal amplitude, the higher of the resistivity, the smaller of the maximum of the initial amplitude will be. The research will provide the necessary reference for complex structure groundwater investigation with NMR.
