Title (EN) FLOWMETER WITH DISCONTINUOUS HELICOID TURBINE
(FR) DÉBITMÈTRE À TURBINE HÉLICOÏDALE DISCONTINUE
Abstract:
(EN) A flowmeter for use downhole estimates fluid flow with a helically shaped spinner member disposed in a path of the flowing fluid. Features, such as magnets, are mounted in the spinner member so that spinner member rotational rate can be sensed, thereby estimating fluid flow. Discontinuities along an axis of the spinner member define segments that are adjacent one another. Adjacent segments can differ angularly, by pitch, as well as by length. With the discontinuities, segment design is less constrained by the geometry of adjacent segments, so that feature locations on the spinner member are maintained, while maximizing sensitivity of the spinner member to fluid flow.
(FR) L'invention concerne un débitmètre destiné à être utilisé dans un fond de trou, lequel débitmètre estime l'écoulement d'un fluide à l'aide d'un élément de centrifugeuse de forme hélicoïdale disposé dans un trajet du fluide en écoulement. Des éléments, tels que des aimants, sont montés dans l'élément de centrifugeuse de telle sorte que la vitesse de rotation de l'élément de centrifugeuse puisse être détectée, ce qui permet d'estimer un écoulement de fluide. Des discontinuités le long d'un axe de l'élément de centrifugeuse délimitent des segments adjacents les uns aux autres. Les segments adjacents peuvent différer angulairement, par leur pas, ainsi que par leur longueur. Grâce aux discontinuités, la conception d'un segment est moins contrainte par la géométrie de segments adjacents, de telle sorte que des emplacements caractéristiques sur l'élément de centrifugeuse sont maintenus, tout en optimisant la sensibilité de l'élément de centrifugeuse à un écoulement de fluide.
