摘要
文章分析了SGDT伽马密度测井仪器原理,运用三次样条函数插值方法对六个方位计数率数值进行插值处理,得到360度方位的连续变化的二维计数率曲线,对插值结果进行成像化处理,可以直观地显示套管周围的水泥密度变化趋势。
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.
