초록 ▼

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.

A production logging tool for use in a tool string to determine fluid holdup of a multiphase fluid flow within a well, said production logging tool comprising: a tool housing having a power supply and an electronics section disposed therein; a plurality of arms rotatably mounted to said tool housing, each of said plurality of arms extending from said tool housing to points distal from a longitudinal axis of said tool housing, wherein said distal points are spaced apart along a satellite path which circumscribes said tool housing; a motor for rotating said plurality of arms about said tool housing to pass said plurality of sensors through said satellite path which circumscribes said tool housing for detecting said variations in said fluid property; an angular position detector for indicating an angular position of said plurality of arms about said tool housing, which determines said angular position for said points at which said plurality of sensors detect said variations in said fluid property; a mechanical power source for selectively controlling said distal spacing between said plurality of arms and said tool housing; a spacing detection means for indicating said distal spacing of each of said points from said tool housing; and a plurality of sensors for detecting variations in a fluid property attributable to different flow constituents of said multiphase fluid flow, wherein each of said plurality of sensors is secured to one of said plurality of arms at one of said points and exposed to said multi-phase fluid flow within said well for determining proportions of said different flow constituents at each of said points.
