摘要： A formation treatment tool assembly is conveyed within a well casing by a tubing string and has a housing defining treatment fluid supply and discharge passages and a fluid injection port through which treatment fluid is directed from the supply passage into a packer isolated casing interval and a fluid inlet port permitting flow from the isolated casing interval to the fluid discharge passage. Spaced straddle packer elements of the tool are energized to establish sealing engagement with the well casing and define an isolated casing interval and are de-energized to retract from sealing engagement with the well casing and permit tubing conveyance. A dump valve connected with the tool housing is opened to permit flow of treatment fluid from the isolated casing interval through the treatment fluid discharge passage and is closed to confine treatment fluid to the isolated casing interval. A hydraulic or mechanically actuated tubing isolation valve is selectively closed to isolate the tubing string from casing or formation pressure and permit tool conveyance while maximizing the service life of the tubing string and to accommodate overpressured and underbalanced reservoir conditions.

摘要： An inflatable packer assembly used in well service work and having a mandrel that carries a normally retracted inflatable packer unit. The unit includes an inner elastomer bladder surrounded by a reinforcement. To control the shape of the unit during inflation and thereby prevent the formation of Z-folds in the bladder, its axial stiffness is preferentially increased relative to its circumferential or hoop stiffness by devices such as carbon fibers or fiberglass tape.

摘要： A method and apparatus for fluid treatment of a selected interval of a well and then cleaning the selected interval and the apparatus of treatment residue. An straddle tool is run into the well to treatment depth on fluid supplying tubing and has upper and lower packers that establish sealing with the casing and define an annular interval between the packers and between the tool and casing. Fluid, such as fracturing fluid, is pumped through the tubing to the tool and is diverted through an outlet port of the tool into an upper portion of the annular interval. Fluid then flows from a lower portion of the annular interval through an inlet port below the outlet port and at low flow rate is dumped into the casing through a pressure responsive dump valve. The outlet port and inlet port are located to accomplish cleaning of residue from the packers.

摘要： An inflatable packer used in a well and having a mandrel carrying upper and lower heads, a normally retracted inflatable packer element including an inner elastomer bladder and an outer expansible armor or carcass, the ends of the packer element being anchored to respective heads, and in one embodiment a hydraulically operable system that applies restraining force to the heads which controls the shape and deployment of the packer element during inflation and prevents entrapment of fluid bubbles outside the element and the formation of Z-folds in the bladder. In other embodiments the restraining force is supplied by a stack of disc springs, by frictional engagement between parts, by a shearing action of materials, by swaging a sleeve member, and by axially crushing a sleeve member.

摘要： An apparatus, system, and method useful for discouraging the extrusion of at least one deformable member of a device into a space adjacent to the deformable member when the device is disposed within a borehole and the deformable member extends from the device to the borehole wall involves at least one expandable member disposed upon the device. The expandable member is expandable into the annulus to reduce the width thereof and retractable therefrom to allow movement of the device within and out of the borehole and redeployment of the expandable member. The apparatus, system, and method are particularly suited for limiting the extrusion of packer elements.

摘要： Durable pumps for abrasives are provided. In one implementation, an example centrifugal pump or pump stage for subsurface operation has a thrust washer located inside the circumference of a close-fitting clearance seal between an impeller shroud and the diffuser. The relocation of the thrust washer allows the clearance seal to protect the thrust washer from abrasives while the thrust washer supports the impeller against the reaction forces of axial fluid flow. In one implementation, the radius or size of a thrust washer or other seal-like feature is reduced in order to increase exposure of the bottom impeller shroud to pressured fluid, thus balancing pressure at the top and bottom of the impeller to decrease friction between the impeller and the thrust washer. Reducing the radius of the thrust washer also reduces surface area of the washer subject to friction and reduces the moment arm of a braking torque on the rotating impeller, thereby reducing power loss in the pump.
摘要翻译：提供耐磨的磨料泵。在一个实施方案中，用于地下操作的示例性离心泵或泵级具有位于叶轮护罩和扩散器之间的紧密间隙密封件的圆周内的止推垫圈。止推垫圈的重新定位允许间隙密封件保护止推垫圈免受磨料磨损，同时推力垫圈支撑叶轮抵抗轴向流体流动的反作用力。在一个实施方案中，减小了止推垫圈或其他密封件特征的半径或尺寸，以便增加底部叶轮护罩对加压流体的暴露，从而平衡叶轮顶部和底部处的压力，以减小叶轮间的摩擦叶轮和止推垫圈。减小推力垫圈的半径也减小了垫圈受摩擦的表面积，并减小了转动叶轮上的制动力矩的力矩臂，从而降低了泵的功率损耗。

摘要： An improved cup packer for use on wellbore tools is disclosed. The open end of the cup packer bore is filled with an elastomer to prevent the intrusion of sand and debris into the space between the cup packer and the wellbore tool on which it is mounted. In an alternative embodiment of the invention, the packer body includes an angularly protruding section at at least one of its ends, wherein the longitudinal dimension of the packer body is at its maximum at its bore. In an additional alternative embodiment of the invention, the open end of the packer is sealed by a screen to prevent the intrusion of sand and debris into the space between the cup packer and the wellbore tool on which it is mounted.

摘要： An inflatable packer apparatus having an inner elastomer sleeve covered by armor such as overlapped, longitudinal slats that extend between upper and lower collars. The end portions of such slats pass through stress rings having outwardly flared nose portions, and thin protector rings mounted inside the nose portions are employed to distribute very localized contact loads form the edge of the slats to the stress rings to prevent the formation of cracks in such rings. The apparatus further includes an elastomeric sleeve member which is expanded into sealing contact with a well bore wall by fluid pressure applied to the inside of the inner elastomeric sleeve member.

The apparatus comprises a sleeve member which is fixed to a part of the drillstring and a rotatable jet head with nozzles through which an abrasive fluid is discharged. The nozzles are mounted such that the fluid jet is directed to an area of the wellbore immediately adjacent to a leading edge of the sleeve. The nozzle head is restricted in its protrusion out of the sleeve.

摘要： A straddle inflatable packer system includes upper and lower packer assemblies each having an inner elastomer sleeve surrounded by expansible armor members. For well treating operations, the upper packer includes an external elastomer sleeve which covers a lower portion of its armor members, and the lower packer has an external elastomer sleeve that covers an upper portion of its armor members, so that the external sleeves are located adjacent to the higher pressures of injected fluids. For well testing operations, the locations of the external packer sleeves are reversed so that again these sleeves are adjacent the higher well bore pressures during the test.
