Analysis of Electromagnetic Log Presentation of Axial Source and Radial Source

Obtain the amplitude rario and the log presenttion of the theory of the phase difference of electromagnetic logging instrument of the centering magnetic doublet source by means of the horizontal multilayer dielectric logging model and the computer analog. Analyzed the characteristics of log presen tation of the electromagneitc theory for the axial source and the radial source under the different measuring conditions, and prede into the possible approaches to increasing the longitudinal resolution of the logging instrument by making use of the explanatory means of the electrical parameter optical value rnaterial in order to offer the theoretical foundation for the development of logging instruments and the explanation of logging materials.
