Abstract
A protective member that is disposed within the longitudinal bore of a well tool, the well tool including an actuating mechanism adapted to be mechanically activated from the longitudinal bore. The actuating mechanism includes an engagement section, preferably a profile. The protective member, preferably a sleeve, substantially covers the actuating mechanism while leaving the engagement section exposed to the longitudinal bore. In a preferred embodiment, the sleeve is slidably disposed within the longitudinal bore between a first position and a second position. A biasing mechanism biases the sleeve into the first position, in which a sleeve first end is proximate the profile. Operation of the apparatus enables a method for preventing the inadvertent mechanical activation of the actuating mechanism of a well tool as peripheral equipment is passed through the longitudinal bore of the well tool.
