Abstract：Log tends to be influenced where borehole environmental condition is unfavorable.The uneven wall of a well,the intrusive mud and mud cake are likely to cause the curve distortion in the depth of well diameter expansion.Density and acoustic curves are most likely to be distorted because their geodesic depth is very shallow.In this paper,the numerical value of the distorted curves was corrected to real measurement range with the multiple regression analysis method and the internal relationship between curves.The correlation between the synthetic seismic record based on the corrected curves and the seismic record near the well was relatively high,and the test results were satisfactory.This method is efficient and easily operable.It offers the high quality data for the calibration between the well and seism.
