    摘要： A method of determining a holdup value for a multiphase fluid. A first holdup component is calculated using a first detection technique which is insensitive to small inclusions of a first fluid constituent (hydrocarbons) dispersed in a second fluid constituent (water). A second holdup component is also calculated using a second detection technique which determines a percentage of the small inclusions of the first fluid constituent that are dispersed in the second fluid constituent. The first and second holdup components are then combined to yield a total holdup value. The method can further compensate for displacement of the second fluid constituent by the small inclusions of the first fluid constituent. The second holdup component is preferably calculated by inferring a maximum heavy phase density (MHPD) of the multiphase fluid.

    摘要： For use with a sonde adapted to be lowered into a well borehole, the sonde supports a thermal conductivity probe response to well fluid thermal conductivity. In the preferred and illustrated embodiment, a four leg resistor bridge circuit has two temperature-sensitive legs exposed to well fluid. In addition, one such bridge leg is positioned adjacent to a heater dissipating constant heat power. The remaining leg is exposed to ambient well fluid. The bridge incremental voltage varies with the ambient temperature of the well fluid, but such ambient variations are compensated for by the remaining temperature-sensitive leg which causes nulling of ambient temperature changes. The heat transferred to the heated bridge leg determines the incremental voltage and, hence, the conductivity of fluid in the well bore can be measured.

    摘要： A production logging tool is provided for use within a well to determine fluid holdup of a multiphase fluid flow within the well. The production logging tool includes a plurality of sensors secured within a plurality of arms which radially extend from a tool housing to points distal from the tool housing. A plurality of sensors are included within the plurality of arms for detecting variations in fluid properties attributable to different flow constituents of the multiphase fluid flow along a path which circumscribes an exterior of the tool housing. The plurality of arms are rotated about the tool housing for moving these sensors through the path in order to ensure that the volumetric proportions of the different flow constituents of the multiphase fluid flow are accurately detected in highly deviated and in horizontal wells.

    摘要： A production logging tool is provided for use within a well to directly measure a velocity profile of a multiphase fluid flow within a cross-section of a well. The production logging tool includes a tool housing from which a plurality of arms are radially extensible. The plurality of arms are rotatably mounted to the tool housing for rotating around a tool axis extending longitudinally through the tool housing. At least one Doppler flow sensor is fixedly mounted to one of the plurality of arms for moving with the arm to dispose the Doppler flow sensor within different localized regions within a cross-section of the well. The localized regions of the cross-section are located at different radial distances from and at different angular displacements around the tool axis of the tool housing, at points distal from the tool axis. The Doppler flow sensor has a depth of investigation for detecting flow velocities of a multiphase fluid flow proximate to the Doppler flow sensor, within the localized regions of the cross-section of the well. The plurality of arms are rotated about the tool housing to dispose the Doppler flow sensor within different ones of the localized regions disposed throughout the cross-section for measuring a velocity profile of the multiphase fluid flow through the cross-section of the well. Flow velocities are also preferably detected within localized regions disposed within the boundary layer of the multiphase fluid flow.
