ON THE RESPONSE OF INDUCTION LOG

Liang Xi-ting  
Not long ago, the author of the paper entitled "The high-order geometric factors of induction logging[3] has,for the first time,determined a formal solution of induction log in total inhomogeneous media which is represented by an infinite series using the micro-disturbance technique. But the convergence of the series has not yet been proved theoretically for the media with non-slowly varying conductivities. Tt is remarked in the paper that in the case of single horizontal layer the result turned out exactly the same as the geometric factor approximation given in[6] while taking off the first-order term of formal solu-tion[3]. However, the unexpected discontinuities on apparent resistivity log might occur for having used such an approximation. Thus one cannot expect the desirable accuracy for utilizing immediately the first-order term of the series given In[3] to the response of induction logging in the non-slowly varying conductivity media. The analysis made in the paper is just to pave the way for utilizing the first-order term of the series solution described as in[3] referred to[4].
