| Abstract: | The author successfully solves the simultaneous inversion problem of geological stratum ture resistivity and the equivalent diameter of invaded zone from the depth and shallow apparent resistivity of bilateral logging, and develops a reliable computational method correspondingly, the main advantage of which is that it does not depend upon the choice of initial value and is therefore of practical value in engineering. The algorithm and program have a very high precision,and meet thereby the requirements for the interpretation of logging data. |
