Use of the technology of acoustic emission in oil field tubular connections

摘要

A monitoring system of threaded connections includes a transducer of acoustic emission connected operationally and positioned to capture a signature sound associated with the formation of the connectionThreaded connection between a first state and a second state. A controller is operationally coupled to the transducer of acoustic emission.The controller may be operated to receive a signal of acoustic emission transducer incorporating the signature sound.The controller may be operated to emit a signal indicating whether the acoustic signature is a threaded connection suitably made of the first and second members or if the signature sound dramaSit a threaded connection sloppy in the first and second members.
