Abstract: The technology of bi-directional data transmission between the well bottom and ground play an increasingly important role in modern drilling technology while drilling. The technology of acoustic data transmission while drilling can achieve higher band rate compared with the traditional. The transducer is one of the most imp-ortant components of it. This article has simulated the piezoelectric ceramic for the parameters, and verified by the measurement of material objects. It has obtained the channel characteristics of the 50 meters drilling string, with the help of the piezoelectric ceramic.

 

Keywords: MWD, Acoustic, Piezoelectric ceramic, Finite element.
