Inverse Problem of The One-dimensional Continuous Conductivity Profile

ZHANG Lian-hai,LIANG Zi-bin,ZHOU Min-du(Lanzhou Institute of Seismology,CEA,Lanzhou 730000,China)  
Based on the Coen inverse algorithm,the inverse determination of one-dimensional continuous conductivity profile from the measurements of apparent resistivity with Schulunberger array is studied.The inversions of presise data and noise data in different conductivity profiles,such as constant function,linear function,power function,exponential function and piecewise function,are given.Using a real field example in which the conductivity profile is determined with layered model by Inman in 1975,we compare the results between our continuous conductivity profile and Inman's and it is found that the method is valid.
