    This paper introduces the principle of the SGDT Gamma density well logging tool.The cubic spline interpolation is used to process the numerical count rate of the six directions.Then we can obtain a continually changing two-dimensional curve with azimuth angle in 360 degree.After the interpolation results are imaged,the trend of the cement density around the casing can be seen clearly and visually.
