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.

摘要： A compression set packer tool (10) includes a mechanism to prevent premature setting of the packer. The mechanism comprises a dog (16) which protrudes into recess (38) on body (12) in a first position, thus locking sleeve (14) and body (12) against relative movement. During operation, the tool (10) is pulled out of polished bore receptacle (32). The dogs (16) are biased radially outwards by springs (70). The tool is then lowered such that a surface (78) of the dogs contacts the top of PBR (32), holding sleeve (14) in position. Further lowering of the tool moves body (12) with respect to sleeve (14), thereby moving shoulder (40) on body (12) towards shoulder (42) on sleeve (14) to compress the packing element (18).

摘要： A device (12) is disclosed which is for use in retrieving debris from a well. In one embodiment, the device includes an elongate body (20); a main bore (22) extending part way along a length of the body, along which fluid flows into the device; an opening (24) towards a lower end of the body; a main fluid chamber (28) in the body in fluid communication with the main bore; a flow restriction (30) provided in the main bore, through which fluid flows from the main bore and into the main fluid chamber; at least one chamber outlet (32) for . directing fluid from the main fluid chamber into an annulus defined between the device and a well borehole wall; a return flow passage (40) extending between the body opening and the main fluid chamber, for return flow of fluid from the annulus to the main fluid chamber, to facilitate retrieval of debris from the well; and at least one fluid exit (44), for flow of fluid returned to the main fluid chamber through the return flow passage out of the device. In use, fluid flowing through the main bore is accelerated through the restriction such that the pressure of fluid exiting the restriction is lower than at a location upstream thereof, to draw part of the fluid returned to the main fluid chamber through the return flow passage into and through the chamber outlet, thereby recirculating said part of the fluid into the annulus. This assists in the retrieval of debris from the well.
摘要翻译：公开了一种用于从井中检索碎屑的装置（12）。在一个实施例中，所述装置包括细长主体（20）; 主孔（22）沿主体的长度分段延伸，流体流过该主孔; 朝向身体的下端的开口（24）; 主体流体室（28）在主体中与主孔流体连通; 设置在所述主孔中的流动限制（30），流体从所述主孔流入所述主流体室; 至少一个室出口（32）。将流体从主流体室引导到限定在装置和井眼壁之间的环空中; 在主开口和主流体室之间延伸的回流通道（40），用于使流体从环形空间返回到主流体室，以便于从井中取出碎屑; 和至少一个流体出口（44），用于通过返回流动通道返回到主流体室的流体流出装置。在使用中，流过主孔的流体通过限制加速，使得离开限制的流体的压力低于其上游位置处的流体压力，以将通过回流通道返回到主流体室的部分流体吸入并通过腔室出口，从而将流体的所述部分再循环到环形空间中。这有助于从井中检索碎屑。

摘要： A downhole tool which can perform a task in a well bore, such as circulating fluid radially from the tool. The function is selectively performed by virtue of a sleeve moving within a central bore of the tool. Movement of the sleeve is effected by dropping a ball through a ball seat on the sleeve. Movement of the sleeve is controlled by an index sleeve such that the tool can be cycled back to the first operating position by dropping identical balls through the sleeve. Embodiments are described wherein the balls are deformable, the seat is deformable and the seat provides a helical channel through which the ball passes.

摘要： A junk removal tool (10) for use in a well bore. The tool includes a multi-faceted face (42) of tungsten carbide to break up large pieces of junk. The junk is then captured in the tool via large area inlet ports (40) and collected in a trap.(31). In one embodiment, valves (41) are placed at the inlet ports to prevent the out-flow of captured junk. A further embodiment includes a throat portion (52) to jet junk laden fluid into the tool.

摘要： A disengageable downhole tool for use in the oil and gas industry. The tool can be decoupled from a work string to allow further tools to be operated from the work string on being run deeper into a well. The tool is then picked-up by the work string on retrieval from the well. In one embodiment a milling tool is described having a hex-drive system for operation of the tool from the work string with coupling and decoupling being achieved via shear pins and a mating ledge and shoulder.

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.
