| Sector cement bond logging tool is a kind of cement bond quality evaluation anddetection of cavity hole sonic logging tool, one trip by instrument measured thedistribution of cement in the eight fan casing, amplitude curves, variable densitycurve, related to the evaluation of cement cementing quality. On the basis of cementbond logging principle, developed the ground sampling module, ground and signalprocessing software,the ground acquisition module, the ground acquisition and signalprocessing software, through the actual measurement, the data show that theinstrument, besides has the function of the conventional cement bond logging tool canalso provide the outside casing cement bond status of visual images, can distinguishthe cement ring radial and longitudinal partial loss, gap and consolidatedinhomogeneity, better meet the needs of cementing quality evaluation. The cementingquality of the equipment in cement bond test has certain advantages and developmentprospects. |
