针对完井中套管内液体密度变化 ,产生微环隙进而影响固井质量的问题 ,分析了微环隙对固井质量的影响及其产生原因 ,给出了微环隙尺寸及其产生水窜的详细计算方法及结果。两口井的实例分析表明 ,实测曲线与计算结果完全符合。
In view of the change of liquid density in casing, the formation of micro-annulus and the influence of cementing quality, the influence of micro-annulus on cementing quality and its reason are analyzed. The micro-annulus size and its channeling Detailed calculation methods and results. The case analysis of two wells shows that the measured curve is in good agreement with the calculated result.
