Analysis of Finite Element Method on Resistivity Imaging Logging

CHEN Ai-xin (Beijing Aeronautics and Astronautics University,Beijing 100083,China)  
Resistivity imaging is the latest method of well logging.The precise simulations of imager are the basis of optimization design and well log interpretation.In view of the complex sources of resistivity imager and heterogeneity of the underground formation,the three-dimensional finite element method is applied to analyze the potential fields excited by the imager.In this paper, the measurement principle of resistivity imager and the approach of obtaining apparent resistivity by finite method are given,some typical formation models,such as horizontal and sloped beds are simulated, and the results are converted to resistivity imager to reflect the formation characteristics on the wall directly.
