With the massive increase in deviated well and horizontal well

the problem of tool eccentricity caused by factors of installation deviation of centralizer and gravity becomes more and more serious. In order to reduce influence of tool eccentricity on response signal

probe centering model based on transient electromagnetic（ TEM）method is established. Combining angle and distance of logging tool to borehole axis

tool eccentricity correction method is proposed. The receiving signals with tool centering and tool eccentricity are analyzed. Experimental results demonstrate that the receiving signal model of tool eccentricity described in the paper can effectively reduce the influence of the eccentricity on casing inspection. The interpretation precision of logging data can be improved and the downhole media information can be better reflected.
