Abstract:
Die Erfindung betrifft eine Pumpvorrichtung (1) zur Förderung eines Fördermediums (4) aus einer von einem Flurniveau (5) in das Erdinnere führenden Tiefenbohrung (5b), die mindestens abschnittsweise mit einer Bohr-Verrohrung (5a) ausgekleidet ist, mit einer Pumpe (2) und einem die Pumpe (2) antreibenden Motor. Indem der Motor (3) außerhalb der Bohr-Verrohrung (5a) angeordnet und über die Bohr-Verrohrung (5a) seitlich durchdringende Drehmomentübertragungsmittel mit der Pumpe (2) verbindbar ist, kann der Motor (3) vor Überhitzung geschützt und im Störfalle unabhängig von der Pumpe (2) aus der Tiefenbohrung (5b) gezogen werden.
Abstract:
An electric submersible pump (ESP) assembly. The ESP assembly comprises an inverted shroud separating a centrifugal ESP pump from a well casing, the ESP pump rotatably coupled to an ESP motor, the inverted shroud having an opening on an upstream terminal side, the upstream terminal side terminating at a head of the ESP motor, at least a portion of the ESP motor extending through the opening, the portion of the ESP motor extending through the opening exposed to formation fluid, and the opening sealed to the formation fluid at the head of the ESP motor tapered and wedged to the inverted shroud, wherein a centerline of the inverted shroud is offset from a centerline of the ESP motor.
Abstract:
A pumping system includes a motor and a drive shaft configured for rotation by the motor. The pumping system includes an upper pump positioned above the motor, an upper pump shaft and an upper directional coupling connected between the drive shaft and the upper pump shaft. The upper directional coupling is configured to lock the upper pump shaft to the drive shaft when the drive shaft is rotated in a first direction. The pumping system further includes a lower pump positioned below the motor, a lower pump shaft, and a lower directional coupling connected between the drive shaft and the lower pump shaft. The lower directional coupling is configured to lock the lower pump shaft to the drive shaft when the drive shaft is rotated in a second direction.
Abstract:
La presente invención se refiere a un aparato de bombeo hidráulico de fondo unidireccional para utilizarse en pozos petroleros, que se instala a la profundidad deseada por el usuario, para incrementar el caudal del agua de formación a reinyectarse / inyectarse desde un tanque de almacenamiento en la superficie a las arenas del yacimiento y a las zonas requeridas. La bomba de superficie inyecta a través de la tubería de producción un caudal de agua de formación, el cual al atravesar la boquilla del aparato de bombeo hidráulico de la presente invención, genera el efecto Venturi por el cual se ocasiona el diferencial de presión que succiona el fluido de formación almacenado por gravedad en el espacio anular existente entre la tubería de producción y la tubería de revestimiento. De esta manera, el caudal así succionado se suma al caudal procedente de la tubería principal, aumentando considerablemente el caudal total de reinyección sin necesidad de incrementar bombas a nivel de superficie.
Abstract:
A well pump assembly (13) has a submersible well fluid pump (19), motor (15), and seal section (17) with a seal section shaft (51)for transferring rotation of a motor drive shaft to a pump drive shaft. The seal section has a shaft passage (49) through which the seal section shaft extends. A movable compensating element (41) has an interior containing motor lubricant that is in fluid communication with motor lubricant in the motor and also in fluid communication with motor lubricant in the shaft passage. A shaft seal (53) restricts well fluid from entry into the shaft passage. A lubricant pump (77) driven by the shaft has a discharge within the shaft passage below the shaft seal. A recirculation passage (85) extends from the shaft passage at a point between the discharge of the lubricant pump and the shaft seal to the interior of the compensating element.
