Well tool stabilizer and method
A stabilizer housing is described for a well tool mounted in a cased subterranean well comprising, in combination: a tubular body connectable in co-axially aligned series relationship to the well tool; the tubular body having a plurality of peripherally spaced, longitudinal slots extending through the wall of the tubular body; a radially expandable linkage disposed in each longitudinal slot; means for pivotally securing one end of each linkage in one end of the respective longitudinal slot; resilient means urging the other ends of the linkages to the radially expanded position; anti-friction means carried by each linkage engageable with the well casing wall in the radially expanded position; releasable means for securing the linkages in the radially retracted position to permit run-in and positioning of the well tool prior to any radial expansion of the linkages; the resilient means comprising a compression spring mounted within the bore of the tubular body; means in the bore of the tubular body defining an abutment engaging one end of the compression spring; a sleeve slidable in the bore of the tubular body and having means on the sleeve engagable with the compression spring; and means for pivotally connecting the other ends of the linkages to the sleeve. The method of stabilizing a downhole well tool relative to a well conduit surrounding the tool is also described.
