1、GENERALINTRODUCTION
The dual transmitter compensating mode can make up for tooldecentralization, transducer consistency, high temperature.etc., improving the accuracy and reliability of logging data. Thetool can locate cement defects while performing conventionalCBL, which betters cement re-filling and channeling positioningwhile identifying micro annuluses and grooves.
It performs CCL, natural gamma, VDL and sector cementbond in one trip.
