| Abstract: | Cement bond logging technology,represented by CBL/VDL,has been a basic method and means to check and evaluate cementing quality for many years and has played an important part in testing cement bond quality in cased hole.While acoustic VDL tools are used,however,some problems frequently occurred,which are not caused by instrument failure.Based on the detailed analysis of the phenomena that often appear in logging operation,this paper points out the reason and provides guidance and help for operators submerged arc welding defect analysis. |
