| Abstract: | Resistivity imaging is the newest method of well logging. The precise simulation of imager is the basis of optimum design of tools and interpretation of well log. In view of the complex sources of resistivity imager and the inhomogeneity of underground formations, the finite element method is applied to analyze the potential fields excited by imager. Some typical formation models are numerical simulated, and the results are converted to resistivity imaging to reflect the formation characteristics on the wall directly. |
