    摘要: A self-retaining cementing wiper plug with a packer element has two or more steel or carbide tipped holddown fingers or slips extending radially outward from the plug for engaging the inner surface of the casing and preventing the plug from moving uphole over time and potentially interfering with other downhole apparatus such as a pump. The packer element in the wiper plug is actuated when the plug is supported by an obstruction under the plug and then compressed, the packer being maintained in compression by the holddown fingers.

    摘要: A stabilizer is provided for stabilizing a rotary or progressive cavity pump suspended from production tubing in well casing. The stabilizer is connected between the production tubing and the pump. The stabilizer has a tubular body having a cylindrical wall and a longitudinal bore contiguous with the production tubing. A releasable sliding dog is disposed on the exterior of the tubular body and is operatively connected by a link to one or more pistons. Each piston is disposed in a piston housing that is in fluid communication with the bore of the tubular body. Circumferentially spaced-apart feet extend radially outwardly from the tubular body. In operation, actuating fluid pressure advances the pistons uphole, driving the sliding dog up one or more longitudinal outwardly extending ramps to brace against the casing, with the feet contacting the casing and bearing opposing reactive force. Preferably, the sliding dog and the feet form a three-point contact with the casing that arrests lateral movement in any direction. Under non-actuating pressure, upward drag on the sliding dog compresses the pistons, retracting the dog, and permitting removal of the stabilizer and pump.

    摘要: A tubing drain valve in a production tubing string, positioned above a pump, is operated to open drain ports in the housing for draining produced fluids from the production tubing when the pump is shut off. The drain valve incorporates a check valve assembly which is freely moveable within the drain valve to shift a sleeve to open and close the drain ports. An uphole end of the check valve assembly is above the sleeve and seals to the top of a sleeve to shift the sleeve downhole and open the drain ports. A downhole end of the check valve is positioned below the sleeve in the valve. When the pump is turned on, the downhole end of the check valve assembly moves uphole to seal to the sleeve, creating a positive force to lift the sleeve to block the drain ports. The produced fluids flow through the valve and the production tubing to surface. The positive force minimizes the effect of fouling of the valve due to debris above the valve which might otherwise result in failure to shift the sleeve uphole, leaving the drain ports open.

    摘要: A frameless switched reluctance motor (SRM) has a stator sandwiched between two housings. Axial load on the rotor shaft is directed through a first bearing, through the first housing to the stator and through the second housing to a motor support. Heat is dissipated using low-loss electrical steel, one or more air movers and air passages through the motor. Preferably a stator profile enables the air passages to be formed through the stator's lamination stack. Optionally air is routed through passages between the coils and through air passages along the air gap and radially through passages between an upper and a lower stator. A first self aligning bearing adapts to misalignment between the first housing and the shaft and a second bearing is provided with transverse movement. Preferably, the frameless motor is adapted for support to a wellhead for driving a downhole rotary pump and a rotary rod string.

    摘要: A self-aligning stuffing box having a spherical joint between the upper and lower portions of the housing permits universal movement of the upper portion relative to the lower portion to permit a rod to pass through the bore if the axis of the rod is misaligned relative to the axis of the bore in each of the upper and lower housing portions. An energized seal in the upper housing resides at or below the spherical joint due to a downwardly depending central portion of the upper housing which extends into a recess formed in the lower housing permitting the height of the stuffing box to be relatively short. A second seal is positioned above the first seal and may be spaced sufficiently above the first seal to permit a flapper valve to be installed between the seals. The flapper valve is mounted through a port in the upper housing which is accessible without disassembly of the stuffing box, the seals or the wellhead.

    摘要: A tool is provided for preventing the rotation of a downhole tool or rotary pump stator, the tool comprising a tubular housing and a jaw which is biased radially outwardly from the tool to engage the casing wall for arresting tool rotation and providing significant stabilization of a rotary pump. In doing so, the tool housing moves oppositely to rest against the casing opposite the jaw. The tool housing and the downhole tool are thereby restrained and stabilized by the casing wall. The tool's jaw is released by opposite tool rotation. Preferably, the jaw is biased outwardly from the tool housing to a casing-engaging position by a torsional member, housed along the axis of the hinge of the jaw. The tool is released from the casing by opposite tool rotation which increasingly compresses the jaw toward the housing, twisting the torsional member into torsion, which then acts to urge the jaw outwardly again. Overextension of the jaw during assembly is prevented using cooperating stops in the jaw and the housing.

    摘要: A self-aligning bearing assembly utilizing PDC buttons for forming opposing circumferential arrays of bearing surfaces, is particularly suitable for use in a fluid environment, such as being immersed in flowing water when supporting the rotor of a hydroelectric turbine. One bearing surface is supported for rotation with the rotor. The opposing bearing surface is supported by a spherical joint in a stationary housing. When the rotor is subjected to hydraulic loading, the opposing bearing surface can be tilted to self-align with the rotor axis.
