摘要： A retainer for movably securing a valve member within a fluid bore of a pump comprises a retainer head which includes at least one peripheral groove and a retainer hub which is connected to or formed integrally with the retainer head. The valve member is movably coupled to the retainer hub, and the retainer head is movable to position the groove over a radial protrusion in the fluid bore. In this position, the retainer is secured to the pump and the valve member is accordingly movably secured within the fluid bore.

摘要： A packer apparatus with a circulating port. A housing of the packer has inflation passages, circulating passages, treating fluid passages, and equalizing passages defined therein. In a straddle packer embodiment, upper and lower packers are mounted on the housing on opposite sides of an outlet of the treating fluid passage. A circulation valve with a sliding differential pressure actuated valve sleeve is disposed below the packers. An inner mandrel is slidably received in the central opening of the housing. The mandrel has a mandrel bore and has upper inflation and circulating ports, lower inflation ports, upper and lower equalizing ports, a treating port and lower circulating ports, all of which communicate with the mandrel bore. The valve sleeve has a valve port. A lug and endless J-slot is operably associated with the housing and mandrel for controlling a telescoping position of the mandrel relative to the housing in response to reciprocation without rotation of the mandrel relative to the housing. The mandrel may also be used to lock the valve sleeve in a closed position. The lug and J-slot define a repeatable sequence of inflating (or deflating) position, intermediate position, circulating position, treating position, equalizing position, and ready position wherein the tool is ready to return to the original inflating position on the next telescoping stroke of the mandrel within the housing.

摘要： An apparatus for hydraulically jetting a well tool having a sliding member includes a positioning tool for operably engaging the sliding member, and a jetting tool connected at a rotatable connection to the positioning tool. The jetting tool is thus rotatable relative to the positioning tool and the well tool. The jetting tool hydraulically jets the well tool as the jetting tool is rotated relative thereto.

摘要： A positive circulating valve with a retrievable standing valve therein. The valve is used with a packer positioned therebelow. The circulating valve comprises a housing with a mandrel slidably disposed therebetween. A J-slot controls movement between open and closed positions. When in the open position, mandrel ports in the mandrel are aligned with body ports in the housing so that bypassing and circulating may be carried out. The standing valve prevents fluid flow downwardly through the tool string below the circulating valve when the circulating valve is in the open position. When the circulating valve is in a closed position, the mandrel ports are in communication with a central opening through the housing, allowing fluid to be pumped downwardly through the circulating valve. The standing valve may be removed so that the circulating valve has a substantially unrestricted flow path therethrough for high flow rate fracturing jobs and the like.
摘要翻译：具有可回收的立式阀的正循环阀。阀门与封隔器配合使用。循环阀包括具有可滑动地设置在其间的心轴的壳体。 J型槽控制打开位置和关闭位置之间的移动。当处于打开位置时，心轴中的心轴端口与壳体中的主体端口对准，从而可以进行旁路和循环。当循环阀处于打开位置时，立式阀防止流体向下流过循环阀下方的工具串。当循环阀处于关闭位置时，心轴端口与通过壳体的中心开口连通，允许流体向下泵送通过循环阀。可以去除立式阀，使得循环阀具有通过其的大体上不受限制的流动通道用于高流量压裂作业等。

摘要： The invention is directed to a coiled tubing swivel for rotatably connecting a first conduit to a second conduit. The swivel comprises a swivel body having a cylindrical receptacle and a flowpath that communicates between the receptacle and the first conduit, a tubular mandrel having a first end that is received within the receptacle and a second end which communicates with the second conduit, and a bearing assembly positioned between the receptacle and the mandrel. The bearing assembly includes a central axis, a cylindrical outer sleeve having an inner surface and a number of annular inner grooves which are formed on the inner surface coaxially with the central axis, and a cylindrical inner sleeve having an outer surface and a number of annular outer grooves which are formed on the outer surface coaxially with the central axis. The outer grooves align with respective inner grooves to define a number of bearing races, and a plurality of balls are disposed in the bearing races to rotatably secure the inner sleeve to the outer sleeve. Moreover, each bearing race comprises a diameter which is smaller than the diameter of the adjacent bearing race that is closer to the first end of the mandrel. In addition, the swivel comprises a packing for sealing the bearing assembly from the flowpath in the swivel body.

摘要： A wash tool includes a housing having upper and lower packer cups attached thereto for sealing between the housing and a casing bore and defining an upper well annulus portion, an intermediate well annulus portion, and a lower well annulus portion. The housing has an upper fluid bypass passage defined therethrough communicating the upper portion and intermediate portion of the well annulus. The housing includes a lower fluid bypass passage defined therethrough for communicating the intermediate portion and the lower portion of the well annulus. A longitudinal housing bore is defined through the housing and has an open lower end so that fluid in the lower portion of the well annulus may return up through the housing bore. The lower packer cup wipes the casing bore as it advances downward through the casing. The fluid exiting the upper bypass passage exits through downwardy directed jets so as to jet wash the intermediate portion of the well annulus as the tool advances down through the casing bore.
