对固井质量解释评价若干问题的探讨

声波水泥胶结测井是检查套管井固井质量的常规方法。该方法虽经过不断完善，仍存在一些问题，如由于仪器的多样化导致解释标准混乱、解释模型简单化和缺乏统一的定量解释标准等。对目前声波水泥胶结测井中存在的问题和影响声波水泥胶结测井的因素进行了分析，对辽河测田的实际刻度井资料进行了分析，在此基础上对固井质量评价提出了一些建议。

Discussion o n Several Problems in the Estimation of Cement Bond Quality

Cement bond logging is a conventional method to check cement bond quality in cased hole. After several decades of development, this technology has improved significantly, but some problems still exist such as disorder of interpretation criterion because of the variety of the logging tools, simplification of the interpretation model and lack of uniform criteria for quantitative interpretation, etc. This paper focuses on the current problems in CBL interpretation and the factors affecting cement bond log.It also analyzes the presentations acquired from calibration pits in Liaohe Oilfield. On the basis of the analysis some suggestions about CBL interpretation technique are proposed.
