摘要： This invention effects a significant reduction in leakage along a piston reciprocating in a cylinder and having a high fluid pressure differential existing between one end of the piston and the other. A large number of closely spaced, annular grooves are provided on the periphery of the piston and the clearance between the non-grooved piston diameter and the interior wall of the cylinder is maintained at a value significantly larger than that commonly employed between a smooth cylindrical shaft and a cylindrical interior sealing surface. The employment of such unexpectedly large clearance not only provides reduced fluid leakage for lighter density fluids when the equipment is relatively new, but the leakage becomes substantially less than that encountered in a smooth surface bearing construction as the piston and cylinder surfaces wear and increase the clearance.

摘要： An articulated, submersible turbine pump for installation in a vertically elongated bottom hole assembly of a well has a flexible shaft and a plurality of rotor elements and stator elements mounted about the shaft in adjacent alternating relationship. Each rotor element has rotatable blades attached to the shaft by a hub and a housing segment surrounding the rotatable blades in outwardly spaced relationship therefrom to provide clearance for rotation. Each stator element has a close fitting hub around the shaft, which serves as a journal bearing, a housing segment outwardly spaced from the hub, and stationary blades attached between the hub and the housing segment. The housing segments are longer than the blades and the hub. Matching conical surfaces are formed at opposite ends of the housing segments to seal adjacent housing segments when axially aligned. An annular relief on the periphery of one of the surfaces permits the housing segments to pivot out of axial alignment when the shaft bends. Axial rotation between the housing segments is prevented by a key and a recess at opposite ends of each housing segment; the key of one segment fits loosely into the recess of the adjacent segment.

摘要： A petroleum well has a plurality of centrifugal pump stages, a jet pump stage, and an electrical drive motor. A recirculated portion of the output from high pressure stages of the centrifugal pump provides power fluid for the jet pump, and the jet pump aspirates fluid from lower pressure centrifugal pump stages. The balance of the output of the high pressure stages goes to the surface as production. The output of the jet pump supplies the high pressure stages. A centrifugal cleaner upstream of the power fluid inlet for the jet pump cleans that stream of particulates. The overall flow rate through the centrifugal stages exceeds the production rate of the pump by the amount of power fluid for the jet pump. The jet pump caps the assembly and can be separately removed for servicing and adapting the pump to the flow requirements of the well.

摘要： This invention provides an improved jet pump having a Venturi chamber defined by a coating of a ceramic or alloy material that is highly resistant to both stress and erosion. The coating is applied by the chemical vapor technique upon a heated substrate of graphite. The graphite is then removed to conform in configuration to that of the coating and reduce the graphite substrate to a thickness of less than 0.010 inches. A mass of low melting, high elastic modulus material is then cast around the graphite substrate with the coating adhered thereto to define an exterior cylindrical configuration. The cylindrical mass is then encased by heat shrinking within a jacket of steel or other similar low modulus, high tensile strength material so as to produce a significant compressive force in the coating.

摘要： While in a well, a downhole turbo-machine of a series of turbine stages and pump stages is driven by power fluid circulated into the turbine stages from the surface. A branch stream from the power fluid passes through a centrifugal cleaner and is cleansed of solid material. The turbine stages drive the centrifugal cleaner. The cleansed stream becomes lubricant for the turbo-machine bearings. On the turbine side, the lubricant stream passes at substantially cleaner discharge pressure into longitudinal passages between turbine shrouds and an alignment tube to journal bearings and journals located between turbine stage stators and a drive shaft driven by the turbines. Annular channels between separate shrouds effect communication between the longitudinal passages between the shrouds and the alignment tube. On the pump side, the lubricant stream is first directed so that it can act on a thrust bearing runner and apply a force in opposition to an otherwise unbalanced axial force. A low pressure discharge from the thrust bearing runner supplies galleries that feed journal and journal bearings of the pump stage stators. Gallery pressure is maintained positive with respect to the pump stage bearings by a feed to the gallery in excess of bleed-out of the bearings. A check valve relieves any excess gallery pressure to that of the next to the last turbine stage fluid passage. Lubricant bleeds from the journals and journal bearings into the fluid stream passing through the turbine pumps.

摘要： A jet pump has a nozzle for a power fluid, a Venturi for the power fluid and a well fluid, and a passage for the well fluid radially outside the Venturi and into the discharge of the nozzle. The power fluid aspirates the well fluid and the combined stream enters the Venturi. The Venturi is ceramic for erosion control. A shell sheaths the ceramic throughout its length and loads the ceramic compressively to provide a compressive preload on it. This preload opposes radial, outward acting stress in the Venturi arising from a greater fluid pressure within the Venturi than the fluid pressure outside it. The preload also produces a friction lock to keep the Venturi from sliding out of the shell because of an axial pressure differential.
