Numerical Simulation of Eletromagnetic Propagation Logging by FDTD in 3-D Cylindrical Coordinates

YAO Jun1,FAN Xiao-min2,WANG Bin1(1.Northwest Branch,Petroleum Exploration and Development Department,CNPC,Lanzhou,Gansu 730020,China;2.College of Geo-Exploration Science and Technology,Jilin University,Changchun,Jilin 130026,China)  
Eletromagnetic Propagation Logging Tool(EPT) is a high-frequency electromagnetic logging tool.It can measure the permittivity of formation,in some cases,it is better than resistivity logging in regard to the distinction between oil and water layer.The FDTD is used to make forward modeling of electromagnetic propagation logging in simple 3-D cylindrical formation,the Mur first order and second order absorbing boundary conditions are used in the different boundaries of cylinder models,then a special method is used to calculate the eletromagnetic fields in the central axis of cylinder models.On this basis,simulated are the responses of electromagnetic propagation logging in oil-water layer,the result is good.
