ABSTRACT:
A sensor protection system for use with an MWD tool includes a tubular body having lesser and greater diameter portions, antennas mounted in grooves in the lesser diameter portion, shield sleeves covering the antennas and being locked in place against longitudinal and rotational movement, and a wear band on the greater diameter portion to provide a standoff for the shield sleeve, the wear band also being locked against movement in the longitudinal and rotational directions. The locking mechanism also can be used to fix a sleeve-type stabilizer on the tubular body.
