Definitions

  • the system cleans used drilling mud, responsive to the nature of the solids in the drilling fluid.
  • the system is preconfigured to handle the flow of fluids with no on-site set up, piping or re-configuration.
  • the system is a closed loop system for removing unwanted drilled solids while minimizing dilution rates of the fluid.
  • the system can also provide cuttings and solids management in two alternate cleaning applications. Further, a cuttings bin or "roll-off" box can be removably installed in the center of the system for cuttings containment or alternatively a low wall can be installed on the system for on-board containment.
  • Figure 3 is a fanciful perspective view of a single stand embodying several optional operating arrangements of the various components of the system of Fig. 1 ;
  • Figure 4B is a schematic illustrating flow paths of a used drilling fluid through the stand of Fig. 3, a parallel separator, single stage arrangement for lighter solids;
  • Figure 5A is a logic flow diagram illustrating the optional sequence of flow of a heavy solids or lighter solids drilling fluid through the system of Fig. 3;
  • Figure 8 is a logic flow diagram illustrating the treatment of used drilling fluid wherein a dewatering agent is added to the used drilling fluid in a drilling mud holding tank, prior to the separators.
  • the platform 22 supports the first separator 28 and the second separator 30 above the first, second and third enclosures.
  • the first separator 28 and the second separator 30 may be centrifuges such as decanter centrifuges.
  • the system 10 may further comprise one or more telescopic lights 46 strategically located on the platform 22 for providing light during night time operations.
  • An on-board power generator that can be housed in the housing 12 such as in the enclosure 16, (not shown) may be provided, which meets most noise suppression requirements.
  • the power generator may be a diesel powered 320 KW generator which functions independently of the drilling rig.
  • intrinsically safe heaters (not shown) can also be provided for preventing equipment from freezing in cold climates and arctic conditions.
  • the system 10 may also remove ultra fine solids by means of chemically enhanced dewatering techniques to provide visually clear water discharge.
  • the system 10 receives used drilling mud at Block 600.
  • a dewatering process may be employed by treating the used drilling mud entering the system with a coagulant or polymer at Block 602.
  • the separators may operate in any configuration as described in the alternative embodiments such as in Figs. 5A & 5B.
  • Clean fluid flows to the holding tank 36 for collection at Block 762. If the clean fluid is suitably light, it can be directed for storage for later reuse in the drilling process at Block 764, else if greater than threshold Y at Block 766, the clean fluids are recycled back to the first separator at Block 754 and second separator at Block 756.

Abstract

Cette invention concerne un système de contrôle des solides qui sépare les solides de la boue de forage usagée. Ledit système est un système en boucle fermée disposé sur un seul châssis mobile. Un premier et un second séparateur sont disposés à des extrémités opposées du châssis mobile. En fonction de la nature des solides qu'elle contient, la boue de forage usagée est dirigée soit vers le premier et le second séparateur en série, où le fluide de forage est alourdi, ou au moins vers le second séparateur si le fluide de forage est léger. Ledit second séparateur peut être un agencement parallèle du premier et du second séparateur. Des agents déshydratants peuvent être ajoutés à la boue de forage usagée avant le premier ou les deux séparateurs. Les séparateurs peuvent être élevés ou abaissés au-dessus des bacs collecteurs de façon à permettre le passage de divers appareils de forage.
