摘要： A method and apparatus are provided for securing a protective sleeve or wear sleeve to a rotary component which is rotatable relative to a rotary seal, such that the wear sleeve is in relatively rotating sealing engagement with the rotary seal. The wear sleeve is secured to the shaft by wedging a lock ring between the wear sleeve and the shaft. Wedging action of the lock ring can be effected by wedging formations, such as tapered surfaces, configured for causing wedging of the lock ring in response to operator-induced axial movement of the lock ring relative to the shaft and/or the wear sleeve. Wedging of the lock ring can be effected by co-operating screw threads on the lock ring and the wear sleeve, so that an operator can tighten the sleeve on the shaft by application of torque thereto.

摘要： A hole cleaning joint for a drill string is deployed into a wellbore penetrating a subterranean formation. The hole cleaning joint includes a tubular body connectable to the drill string and a hole cleaning section positionable about the tubular body. The hole cleaning section has an outer surface engageable with a wall of the wellbore. The outer surface has spiral grooves extending therein defining blades therebetween, and an uphole end and a downhole end with a spiral cavity therebetween. The spiral cavity has a width that decreases towards the uphole end of the spiral cavity to define a tapered flow channel to receive cuttings therethrough whereby uphole movement of cuttings is facilitated during drilling.
