Study On The Influence Factors Of Reception Performance Of Acoustic Logging Receiver

Receiver is an important part of acoustic logging tool,it has a direct impact on the effect of sonic logging.Commonly receiver performance mainly refers to the bandwidth,sensitivity and directivity,receiving performance's good or bad influence on the signal-to-noise ratio of the received signal,thus affecting the formation information accurately extracted and the reliability of well logging interpretation,so the influence factors of the receive sensor performance to improve the accuracy of the receiver when receiving formation signal and improve instrument performance is of great significance.This paper,which using a combination of numerical simulation and experimental approach explores the various effects of factors.Numerical simulation is based on ANSYS software to simplify the actual model,approximate,build a physical model,and then solve it through the finite element method.Experience is completed in a ??45m5mm pool,this method mainly test the changes of the different receiver performance.The study shows: Structural parameters,the shape and mode of operation of receiver affect its sensitivity,bandwidth and directivity.
