Forward simulation for electromagnetic tomography and optimized design for sensor parameters

WANG Bin-Tao,WU Xi-Ling,WANG Xiao-Xing Research Center of Well Logging,Faculty of Natural Resource & Information Technology,China University of Petroleum,Beijing 102249,China  
Firstly,FEM (Finite Element Method) is used to analyze forward problem and compute real potential and imaginary potential at different manifold distribution.Secondly,study the effect of the number of sensors,the angle and electrode thickness.Thirdly,the optimized parameters of EMT are gotten by neural network method.The parameters of sensor design are optimized by using neural network method.It can be found that the effect of potential is mainly affected by medium distribution,especially the imaginary potential distribution.The different number of sensors affects the measurement largely and the potential is affected by different angle and electrode thickness to some extent.
