摘要： A downhole cleaning tool for cleaning a casing is provided with a diverter cup assembly (102) including a housing (126) and a resilient swab cup (105) slidably mounted on a tubular body (120) with an increased external diameter portion 128 defining at either end upper and lower limit stops (130, 132), and sized to make provision for a gap (136) which allows a sliding movement of the swab cup such that only one of limit stops (130, 132) engages to always pull the swab cup via optional bearings (134) at each extremity of the sliding travel according to whether the tool is being run in hole or pulled out of the hole. This means that the swab cup is not compressed into a squat oversize shape susceptible to contact damage, and is naturally drawn out to tend towards an elongate shape in either direction of tool motion.

摘要： A cleaning tool for cleaning a liner top in a well bore. The tool includes cleaning elements, typically scrapers, which are arranged eccentrically to an axial bore through the tool. The elements are biased outwardly to contact an inner surface of a polished bore receptacle (PBR) at a position with a curvature to match the PBR and to present leading edges of each element when positioned at a surface of a neighbouring casing. The tool may further provide a top dress mill and act as a packer actuator sub. This provides a tool which performs a number of functions on a single trip in a well bore.

摘要： A downhole tool which includes a locking bar to allow movement of a sleeve within the tool over a pre-defined range. The range is defined by a recess arranged axially or circumferentially in the tool, in which the bar locates. Fluid can be vented from the recess to provide a hydraulic brake, to prevent premature shearing of any shear pins in the tool. A stabiliser, jetting and circulating tool is described including the locking bar together with applications when incorporated in a bottom hole assembly. The tool allows multiple operations to be performed on a single trip.
