This paper studies systematically the mathematical models for computing the electrical logging abnormalities in a well, and has derived formulas for computing the abnormalities of the ellipsoidal electrical bodies. The expressions with coordinate coefficients have been simplified into forms which are easy to compute with the aid of auxiliary formulas and ellipsoidal integration with the lower limit of integration being 7, which is discussed by evaluating the biggest real root of ellipsoidal equation of common form. On the basis of forward computing, an approximate processing method closely conforming to real condition is proposed and analytical expression for computation is given with better mathematical models set up and a better computing method obtained, so that we can correctly understand the regularity of electrical abnormalities and arrang field work in a more rational way and choose better method and technique. It is of practical valve for doveloping new method, technology and making qualitative and quantitative interpretation.
