摘要:
A multiphase flow meter comprising two Venturis separated by a choke. The choke may be varied to adjust the properties of the multiphase fluid flow being measured. The two Venturis may be identical and may be arranged horizontally with respect to the multiphase fluid flow. The choke may be a choke in a return line of a managed pressure drilling system.

Methods and apparatus are described for sampling and diluting concentrated emulsions, which may be oil-in-water emulsions, water-in-oil emulsions, or other concentrated emulsions. One method embodiment of the invention comprises obtaining a sample of a concentrated emulsion comprising a dispersed phase and a continuous phase fluid; measuring droplet concentration of the dispersed phase in the sample; and for droplet concentration of the sample greater than about 1000 ppm, diluting the sample with substantially pure continuous phase fluid, forming a first diluted emulsion. Methods of the invention include those wherein the obtaining of a sample comprises opening a fluid connection to a flowing stream comprising the concentrated emulsion, wherein the obtaining and diluting steps occur in real time.
摘要:
A production logging tool for measuring at least one property of a surrounding fluid in a wellbore, comprising a shaft and a rotatable member coupled to the shaft, the rotatable member comprising a sensor component, the arrangement being such that on rotation of the member the sensor moves in a path transverse to the length of the shaft.

摘要:
Embodiments of the present invention provide systems and methods for downhole sampling or sensing of clean samples of component fluids of a multi-fluid mixture. More specifically, but not by way of limitation, embodiments of the present invention provide for, amongst other things, separating downhole multi-fluid mixtures into an oil-based fluid, a water-based fluid and/or the like and sampling and/or sensing of the clean separated fluids. Such sampling or sensing may be provided by a downhole tool in accordance with some embodiments of the present invention and the downhole tool may be used for production logging, formation testing and/or the like.
摘要:
An apparatus (and corresponding method) for characterizing the fluid properties of a two phase fluid includes a restriction element (e.g., orifice plate or nozzle) along the flow path of the two phase fluid. At least one temperature sensor measures temperature of the two phase fluid flowing through the restriction element. A pressure sensor measures the pressure downstream of the restriction element. Time-of-flight measurements of pulses passing through the two phase fluid are made. The speed of sound within the two phase fluid is calculated from the time-of-flight measurements. At least one fluid property (e.g., a vapor phase fraction) of the two phase fluid is calculated from the measured pressure, the measured temperature, and the calculated speed of sound.
摘要:
A technique for controlling fluid production in a deviated wellbore is disclosed. The technique utilizes a flow pipe the interior of which is in hydraulic communication with the earth's surface. A plurality of flow control valves are disposed at spaced apart positions along the length of the flow pipe. The flow control valves are used to regulate flow along intervals of the flow pipe.
摘要:
The invention relates to an apparatus for separation of a first fluid from a mixture of at least the first fluid and a second fluid and a method for doing the same. The apparatus is preferably located downhole, but also can operate on the surface. According to the invention, the apparatus comprises:—a production pipe for flowing the mixture;—at least one settling chamber surrounding the production pipe;—at least one aperture allowing the mixture flowing into the production pipe to flow into the settling chamber; and—an exit pipe, connected to the settling chamber, allowing the first fluid to flow out of the settling chamber.
