Title (EN) GAS TIGHT HORIZONTAL DECANTER FOR DRILLING WASTE SOLIDS WASHING
(FR) DÉCANTEUR HORIZONTAL ÉTANCHE AUX GAZ POUR LAVAGE DE DÉCHETS SOLIDES DE FORAGE
Abstract:
(EN) A hermetically sealed horizontal washing decanter centrifuge for enhanced drilling fluid recovery and drilled solids washing. A process and apparatus for liquid phase -solid phase separation of oil based drilling mud-containing drill cuttings is described including flowing the drilling mud-containing drill cuttings into a horizontal washing decanter wherein the stresses imposed within the decanter act as a wash as the diluent and oil based drilling mud move away from the drill cuttings. Diluent is added prior to flowing the drilling mud containing drill cutting to the hermetically sealed horizontal washing decanter centrifuge. The entire process is performed in a gas-tight environment preventing escape of diluent from the process into the external atmosphere and preventing introduction of gases into the process from the external atmosphere.
(FR) Centrifugeur-décanteur à lavage horizontal hermétiquement fermé destiné à améliorer la récupération du fluide de forage et le lavage des solides de forage. L'invention décrit un processus et un appareil pour la séparation de phase solide-phase liquide de déblais de forage contenant des boues de forage à base d'huile comprenant l'écoulement des déblais de forage contenant des boues de forage dans un décanteur à lavage horizontal, les contraintes imposées dans le décanteur agissant comme un lavage quand le diluant et les boues de forage à base d'huile s'éloignent des déblais de forage. Le diluant est ajouté avant l'écoulement des déblais de forage contenant des boues de forage jusqu'au centrifugeur-décanteur à lavage horizontal hermétiquement fermé. Tout le processus est réalisé dans un environnement étanche aux gaz empêchant l'échappement de diluant du processus dans l'atmosphère extérieure et empêchant l'introduction de gaz dans le processus depuis l'atmosphère extérieure.
