摘要
本文通过对5口井不同条件下86次声波测井资料及近几年部分可对比井的声波测井资料分析,阐述了时间推移、加压、射孔、压裂酸化等条件下水泥胶结评价情况。分析了影响固井质量评价诸因素,探讨了同一口井GFC-74型国产声幅仪与引进CSU的SLT-N声波变密度测井仪评价固井质量差异的原因。
This paper studies 86 acoustic cement bond logs run in 5 wells under different conditions, such as, at different elapsed time, different pressure, before and after perforating, before and after acid treatment The factors which influence cement evaluation results are discussed in this paper. An example is given in which an acoustic amplitude log with a China-made GFC -74 tool and a VDL log with Schlumberger SLT-N tool were run in same well for cement evaluation. The reason for their different resutls is analyzed.
