METHODS AND APPARATUS FOR OPERATIVELY MOUNTING ACTUATORS TO PIPE

摘要

An apparatus for mounting one or more transducers to a drill pipe. The apparatus comprises a sub-pipe having a bore and a transducer-holding assembly, wherein the transducer-holding assembly is insertable into the bore of the sub-pipe from an axial end of the sub-pipe. The apparatus further comprising a tension collar connected to the bore-defining surface of the sub-pipe and bearing upon the transducer-holder.

1. An apparatus for mounting one or more transducers to a rotatable drilling pipe stand comprising:
a sub-pipe comprising a bore-defining surface defining an axially oriented bore therethrough, a connector at a first axial end, and a connector at a second axial end, at least one of the connectors connectable to the rotatable drilling pipe string for rotation of the sub-pipe, while drilling, and for corresponding transmission of torque through the drilling pipe string and the sub-pipe to a drill bit connected to the drilling pipe string; and a transducer-holding assembly comprising one or more transducers, the transducer-holding assembly operably insertable into the bore of the sub-pipe from one of the first and second axial ends and mountable in the bore of the sub-pipe to provide intimate contact which facilitates acoustic communication between the one or more transducers and the sub-pipe.
