A pumping system (10) for injecting buoyant spheres (12) into an oil or gas well (14) having a feeder (26) containing a plurality of buoyant spheres (12); and a sphere pump (24) in proximity to the feeder (26), having first and second rotatable wheels (30, 32), wherein the first wheel (30) has a plurality of notches (33) and the second wheel (32) has a corresponding plurality of notches (34), such that during rotation of the wheels (30, 32) the first and second wheel notches (33, 34) temporarily combine to form a plurality of pockets (40), wherein each pocket (40) receives then ejects one of the plurality of buoyant spheres (24) from the feeder (26) during rotation of the first and second wheels (30, 32).
Selon l'invention, un système de pompage (10) d'injection de sphères flottantes (12) dans un puits de gaz ou de pétrole (14) comprend une voie de passage (26) renfermant une pluralité de sphères flottantes (12), et une pompe de sphères (24) située à proximité de la voie de passage (26) comporte des première et seconde roues rotatives (30, 32). Ladite première roue (30) est pourvue d'une pluralité d'encoches (33) et ladite seconde roue (32) possède une pluralité correspondante d'encoches (34), de telle manière que pendant la rotation des roues (30, 32), les encoches des première et seconde roues (33, 34) se combinent temporairement pour former une pluralité de poches (40), chaque poche (40) permettant de recevoir et, puis, d'éjecter une des sphères flottantes (24) provenant de la voie de passage (26), pendant la rotation des première et seconde roues (30, 32).
