Principle of dual induction tool's field calibration and method for adjusting dual induction log zeros are introduced in this paper. The reasons for the abnormal phenomenon of induction logging curves from the tool are induced and analyzed in theory. One is incorrect adjustment of the induction log zero, the other is no calibration in time. A case example shows the derivation and analysis are right. Furthermore, a systematical summary on the method for adjusting dual induction log zero is given in detail according to the abnormal phenomenon. In the end, some suggestions on the field adjustment of dual induction log zero and its field calibration are proposed.
