A junk basket for collecting junk from a well bore and adapted for external connection to a well drilling string. The junk basket includes an elongate body having an annular interior for a releasable attachment to the exterior of a portion of the drilling string. The body includes an upwardly directed cavity for receiving junk from the well bore and one or more drain holes through the body adjacent the bottom of the cavity for draining fluid. Ribs are provided in the cavity connected to the body for engaging the exterior of the drilling string for reinforcing the body and guide means, preferably positioned on the top of the ribs, extend upwardly for preventing the top of the body from catching on downwardly facing shoulders in the well bore. The junk basket may be releasably connected to a drilling string by providing a downwardly facing shoulder in the interior of the body and resilient male and female split rings positioned in the interior of the body which are actuated by an end cap threadably connected to the body. Axial movement of the end cap causes axial movement of the rings relative to each other for engaging or disengaging the drilling string. Positive locking screws and elongate slots are provided on the body and end cap for rotationally locking the body and cap together.

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.
