摘要
A system for securing a measurement-while-drilling (MWD) instrument in a generally centralized position within a protective drill collar. The system includes a pressure responsive slidable contact pad member in combination with a plurality of fixed contact pad members. As the instrument is subjected to an increase in pressure, above atmospheric, a slidable contact pad member moves longitudinally along an inclined angle face of a base member into contact with the inner wall of the drill collar to thereby centralize and secure the instrument within the drill collar.
