| Abstract: | Based on the electromagnetic field theory, this paper derives the theoretical formulae for the cross-well formation resistivity logging through casing, conducts numerical calculation, and analyzes the influence of casing on the cross-well resistivity logging. The result shows that the new method using low frequency electromagnetic wave to measure the formation resistivity through casing is effective. The theory can provide a theoretical foundation for the development of logging tools, for the interpretation of casedhole logging and for the technique of cross-well formation resistivity tomography through casing. |
