Abstract:
A logging tool includes a tool mandrel, an antenna disposed on the tool mandrel and including one or more coil windings wrapped about the tool mandrel, an antenna shield disposed about the antenna and including at least two pieces, and a constraining element to limit rotational motion of the antenna shield about the tool mandrel. The constraining element is disposed in a through hole defined in the antenna shield and a cavity defined in the tool mandrel, and the antenna shield and the tool mandrel are coupled to each other via an interference fit between the constraining element and the through hole and the cavity.
