摘要： A method and apparatus for determining a volume of a phase of a multiphase fluid flowing in a production tubular is provided. A magnetic field is imparted on the fluid to align nuclei of the multiphase fluid along a direction of the magnetic field. A radio frequency signal is transmitted into the multiphase fluid to excite the nuclei, and a signal is detected from the nuclei responsive to the transmitted radio frequency signal. An amplitude of the detected signal is determined and the volume of the phase flowing in the production tubular is determined using the determined amplitude and an amplitude of a calibration signal.

摘要： En fremgangsmåte og apparat for å bestemme et volum til en fase av et flerfasefluid som strømmer i et produksjonsrør er fremskaffet. Et magnetisk felt er overført på fluidet for å innrette kjerner til flerfasefluidet langs en retning av det magnetiske felt. Et radiofrekvenssignal er utsendt inn i flerfasefluidet for å eksitere kjernene, og et signal er detektert fra kjernene som reagerer på et utsendt radiofrekvenssignal. En amplitude til det detekterte signal er bestemt og volumet til fasen som strømmer i produksjonsrøret er bestemt ved å benytte den bestemte amplitude og en amplitude til et kalibreringssignal.

摘要： A plurality of electronically controlled downhole tools and systems for use in production wells is presented. These tools and systems include a safety valv e position and monitoring system, where pressure is measured upstream and downstream th e valve, at the hydraulic valve control line and in the annulus between the valve housing and the wellbore; a proximity sensor provides information about the valve position; an inflatable packer having a motor operated valve for closing and opening the inflation fluid passage; a tool stop located in a side pocket mandrel having a threade d shaft operated by an electric motor and a stop pivotably connected to the shaft fo r being raised from a position within the side pocket into the main passage of the mandrel for blocking the main passage in order to stop other tools being run into the wellbore; a fluid/gas control system located in a side pocket mandrel comprising a motor connected to a gas regulator section and a fluid regulator section followed by a telescopic section which allows the regulator sections to be shifted axially with respect to a lateral inlet port provided in the side pocket; a shut-off valve and variable choke assemb ly comprising two ball valve chokes having sequentially smaller apertures and a ball shut-off valve, all valves being connected to the drive shaft of a stepper motor; a downhole sensor comprising a side pocket mandrel for removably arranging a sensor for measuring flow parameter or formation evaluation data.

摘要： An optical sensing member within the anullus zone of a well is disclosed, which sensing member determines the level of debris in the well. When debris accumulates within the anullus zone, said sensing member returns a signal indicative of the level of such debris within the zone. The optical sensing member may include an optical fiber and/or any known optical sensors configured to determine strain, pressure, shape, force, and/or temperature.

摘要： Downhole tools (15) and systems can be actuated chemically by placing a chemical sensor (14) downhole and introducing a chemical slug (16) into fluids being pumped downhole. When the slug reaches the sensor a reaction in the sensor may be employed to trigger an event (e.g., actuation) or may cause a count to increase by one on its way to a full count an actuation of a tool or a system downhole.

摘要： The apparatus includes a signal sensing demodulator device and a skin fricti on sensing device positionable within the wellbore. Both devices are in informational communication with each other. The method includes exposing th e skin friction sensing device to a fluid flow, transmitting a signal obtained as a result of a movement of the skin friction sensing device from the fluid flow to a signal sensing demodulator device, converting the signal to a numerical value, and computing a parameter or parameters of the fluid flow i n the wellbore from the numerical value.
