The method is applicable to determining hold-ups of different phases of the fluid.

摘要： A flow rate device for measuring the flow rate of a fluid flowing through a wellbore is disclosed. The flow rate device includes a differential pressure conduit, a flow restrictor insert and a differential pressure measurement device. The differential pressure conduit is locatable in the wellbore, defines an internal bore, and is adapted to include a restriction having a cross-sectional area to increase the velocity of fluid flowing through the differential pressure conduit to create a differential pressure. The differential pressure conduit defining first and second pressure measuring stations axially spaced along the differential pressure conduit. The flow restrictor insert is located in the restriction to reduce the cross-sectional area of the restriction. The flow restrictor insert defines an internal bore having a cross-sectional area less than the cross-sectional area of the restriction. The flow restrictor insert also has a pressure measuring port aligned with the second pressure measuring station. The differential pressure measurement device has at least one pressure sensor for detecting the pressure at the first pressure station, and for detecting the pressure at the second pressure station to generate a signal indicative of the flow rate of the fluid.

摘要： To acquire data such as the flow rate of various phases of a fluid flowing in a hydrocarbon well (12) in production, in particular in an inclined or horizontal portion of the well, both the local speed of the fluid and the proportions of the various phases are determined in each of at least two distinct regions of the well that are not in alignment with one another parallel to the axis of the well. The regions in which the measurements are taken are advantageously distributed in a vertical plane containing the axis of the well when the well is inclined or horizontal.

摘要： A well for producing oil from an underground formation, comprises a vertical section extending from the surface to a depth below the oil-producing formation; a sidetrack or perforated interval (production zone) extending from the vertical section into the oil-producing formation; and a valve, located in the well, and operable to prevent flow of fluid from the vertical section into the production zone and a valve to prevent flow of fluid from the portion below the production zone into the production zone or into the vertical section above the production zone. A method of producing oil from the well comprises allowing oil and water to flow into the well via the production zone until the hydrostatic pressure of the oil and water in the well balances the formation pressure of the oil-producing formation such that further flow into the well ceases; allowing the oil and water in the vertical section of the well to separate under gravity so as to produce (i) a lower layer of water, at least part of which is located in the part of the vertical section below the oil-producing formation, and (ii) an upper layer of oil having its upper surface below the well surface and its lower surface above the production zone; forcing the separated oil and water back down the well and operating the valve such that substantially no fluid is forced into the production zone, an water is forced into the underground formation below the oil-producing formation; and allowing oil and water flow to recommence from the production zone.
