Numerical simulation of static magnetic filed distribution of NMR logging tools
|
Abstract:
In order to optimize the magnet design and accelerate the development of NMR logging tools,a mathematic model of static magnetic field distribution of NMR logging tools is established in this paper.Finite element method is employed to solve 2-D distribution of three NMR logging tool such as MRIL,CMR and MREx.It is very convenient to get the magnetic field distribution of any shape magnet,and the precision of results is very high.
