Abstract
A rigid drilling stabilizer having outwardly extending ribs is slidably received over a tubular member. A plurality of tapered slip segments are located around the tubular member and within and near each end of the rigid main body of the stabilizer. An end cap is threadedly engagable within each end of the rigid main body. Each slip segment has an inwardly projecting rib and adjacent recess which conform to the corresponding annular recess and rib on the end caps. As an end cap is threadedly engaged to the rigid main body of the stabilizer, the tapered slip segments are urged axially inwardly against a conforming tapered surface within the rigid main body. The slip segments are wedged against the rigid main body and against the tubular member thereby locking the stabilizer to the tubular member. As the end cap is threadedly disengaged from the rigid main body, the slip segments are mechanically disengaged from the rigid main body and the tubular member thereby permitting the stabilizer to be removed or relocated.
