Acoustic amplitude logging is a kind of acoustic logging method for detecting the cement degree of consolidation outside sleeve pipe.Use single-shot list
Quiet down and be, i.e., one transmitting probe, a receiving transducer, between the two at a distance of fixed distance.Transmitting probe launches sound wave
Afterwards, by the propagation in sleeve pipe, it is then return in well and is detected by receiving transducer, amplitude and the outer cement of sleeve pipe of its acoustic signals
The bonding quality of ring has relation.It is more firm cement outside sleeve pipe, cement is more dredged when cementing poor when general cementing preferable
Pine does not have cement but water or air.When degree of consolidation is preferable, the energy of acoustic signals can be penetrated into outside sleeve pipe
Cement in, therefore, the acoustic signals amplitude that receiving transducer is received is smaller.Conversely, when degree of consolidation is poor, acoustic signals
Energy is largely retained in sleeve pipe, and is received by receiving transducer, therefore acoustic signals amplitude is higher.No matter sonic system is in well
In any position, due to the medium and distance of propagation be it is relatively-stationary, therefore, acoustic signals reach receiving transducer time
