摘要： The present invention relates to a downhole pumping assembly for being introduced in a well inside a casing and submerged in well fluid, the downhole pumping assembly extending in a longitudinal direction and being adapted for connection with a wireline. The downhole pumping assembly comprises a pump section comprising a tubular pump housing providing a pump chamber, an inlet provided in the tubular pump housing, the inlet being in fluid communication with the pump chamber, a first valve which is a one-way valve for opening and closing the inlet, a plunger slidingly disposed in the pump chamber, a pump rod operably connected to the plunger and extending from the plunger through the tubular pump housing, an outlet provided in the tubular pump housing, the outlet being in fluid communication with the pump chamber, a second valve which is a one-way valve for controlling a flow of fluid through the outlet. The downhole pumping assembly further comprises a linear actuator arranged in association with the tubular pump housing for driving the pump rod, whereby, when the downhole pumping assembly is at least partially submerged into the well fluid, well fluid is drawn into the tubular pump housing through the inlet and expelled through the outlet in the tubular pump housing, and the pump section further comprises at least one sealing element for isolating a first part of the casing from a second part of the casing.

摘要： An artificial simultaneous production and maintenance system assisted by mechanical pumping with flexible tubing for fluid extraction, comprising: a surface assembly including a sub-base, a hydraulic drive head, a stuffing box, an O-ring preventer, a wedge preventer and a connection and splicing means; from the surface assembly a production tubing extends vertically downwards inside the well bore; a casing; a flexible tubing located inside the production tubing all along its length, being the casing, the production tubing and the flexible tubing concentrically one inside the other; and a pump assembly including a connector, a check valve, cleaning tool, standing pump. The system allows assisted production by mechanical pumping for fluid extraction and maintenance by simultaneous pumping of chemicals to the well to modify physical properties of the fluid to be extracted and clean organic and inorganic material buildup within the well.

摘要： The invention relates to dispensing slow release chemicals for inhibiting the formation of scale, corrosion or other precipitates in hydrocarbon wells. The chemical is provided into a dispenser positioned for at least nearly continuous exposure to liquid preferably in the active water phase. The active water phase is generally just below the inlet into production tubing.

摘要： The present invention describes a pumping device (1) for pumping fluids. The pumping device (1) comprises a force transmitting element (2), a tension unit (3) coupled to the force transmitting element (2) and a seal element (10). The force transmitting element (2) is adapted for transferring an upstroke and a downstroke to a pump plunger (5) for pumping fluid (12). The tension unit (3) is adapted for applying a tension force (F) to the force transmitting element (2) for keeping the force transmitting element (2) under tension during the upstroke and the downstroke. The seal element (10) is adapted for sealingly preventing pumping fluids (12) during the downstroke and for enabling pumping fluid (12) during the upstroke. A part (16) of the seal element (10) is rigidly coupled with the force transmitting element (2).
