  • the RPE (0305) may pressure lock against CSS (0306) when differential pressure is applied i.e., when the pressure upstream (production or heel end) of the RSM (0303) location is greater than the pressure downstream (injection or toe end) of the RSM (0303).

This is due to the increase in surface area, but more importantly, the fact that the exemplary hollow passage restriction plug element dissolves from the inside and the outside at the same time, thus improving the lime to removal of the ball while plugging the seat for the same amount of time.
  • the charts (4700, 4800) demonstrate experimental tests where the diameter of the exemplary ball with drilled hole reduced at the same rate as the solid ball, but the time to total degradation is significantly reduced by the addition of the hollow passage.

Abstract

L'invention concerne un élément et un procédé de bouchon de restriction pour positionner des bouchons permettant d'isoler des zones de fracture dans un puits de forage horizontal, vertical ou dévié. L'élément de bouchon de restriction comprend un passage creux partiel avec une extrémité intérieure. Le passage partiel permet à l'élément de bouchon de se loger dans un élément de manchon de restriction pendant le traitement et se dégrade par la suite pour former un passage creux complet. Le canal d'écoulement complet dissout ou dégrade non seulement l'extérieur mais également l'intérieur de la paroi de l'élément de bouchon de restriction. Initialement, l'écoulement est limité par l'extrémité fermée dans le passage creux partiel et, au fil du temps, le canal d'écoulement s'ouvre par dégradation et permet au fluide de traverser dans l'une ou l'autre direction. Pendant un reflux dans le puits, un nouveau fluide est mis en circulation dans le puits et l'élément de bouchon de restriction continue de se dégrader.
