Drill cuttings are disposed of by injection into a subsurface formation (12) by way of an annular space (26) formed in a wellbore (10). the cuttings are removed from the drilling fluid, conveyed to a shearing and grinding system that converts the cuttings into a viscous slurry with the addition of water. The system comprises a receiving tank (48, 50) and a centrifugal pump (56, 58) for recirculating the mixture of cuttings and water (seawater) between the pump and the receiving tank. A discharge conduit (76) is connected to the pump (56, 58) for moving the viscous slurry to an injection pump (78) for high pressure injection into the formation.
Les débris de forage sont éliminés par injection dans une formation souterraine (12) par l'espace annulaire (26) entourant le tubage d'un puits (10). Les débris sont séparés du fluide de forage, transportés vers un broyeur où ils sont transformés en boue épaisse par ajout d'eau. Le système comprend un réservoir de réception (48, 50) et une pompe centrifuge (56, 58) servant recirculer le mélange de débris et d'eau (eau de mer) entre la pompe et le réservoir de réception. Un tuyau de refoulement (76) raccordé à la pompe (56, 58) sert à acheminer la boue épaisse vers une pompe d'injection (78) haute pression pour son injection dans la formation.
