H-SGDT-NV伽马-密度-厚度测井仪及其应用

H-SGDT-NV gamma-density-thickness logging tool and its application

H-SGDT -NV伽马 -密度 -厚度测井仪是一种在固井质量评价中用于测量套管外水泥环平均密度、套管厚度、套管偏心的测井仪器 ,该仪器的测量结果与声波变密度测井仪测量结果综合起来 。

H-SGDT-NV gamma density thickness logging tool is applied to measure cement sheath average density,casing thickness and casing eccentricity in cement quality evaluation.The logging tool has many advantages such as design ingenuity,unique construction,high integration and so on.The paper focus on introducing instrumental function,technique advantage,working principle and its applied effictiveness.
