Abstract:
1. An adjustable bent housing, comprising: an outer tubular member having an interior surface defining an interior bore, the outer tubular member having a first angular offset; an inner tubular member having an exterior surface, the inner tubular member having a second angular offset, the inner tubular member having at least one engagement end received within the interior bore of the outer tubular member, a desired cumulative angular offset being selected by relative rotation of the outer tubular member and the inner tubular member to adjust the positioning of the first angular offset relative to the second angular offset; a rotational stop limiting relative rotation of the outer tubular member and the inner tubular member to a limited rotational range; and a rotational lock for locking the outer tubular member and the inner tubular member in a selected rotational position within the rotational range to set the cumulative angular offset.
