固井水泥环胶结质量检测与评价技术研究

Study on Testing Method and Evaluation Technology of Cement Bond Quality of Well Cementation

基于声波测井原理,进行固井水泥环胶结质量检测方法研究。制作了不同环空间隙、胶结情况的介质模型,分析测井CBL值与套管波首波声幅幅值的关系;通过套管波首波声幅幅值预测水泥环环空间隙和胶结强度,探讨水泥环室内胶结质量评价方法。

Based on acoustic logging principle,this paper focuses on the research about cement bond quality test method.By making medium model of different annular gap and cement bonding,the connection between CBL value and first acoustic amplitude value of casing is analyzed;prediction of cement annular gap and bond quality performance is carried out with the help of first acoustic amplitude value of casing,to discuss the evaluation method of indoor cement sheath bonding quality.
