Title (EN) PLANT FOR TREATING DRILL CUTTINGS
(FR) INSTALLATION DE TRAITEMENT DE DEBLAIS DE FORAGE
Abstract:
(EN) The present invention relates to a plant for treating waste materials, which plant performs a safe and permanent depositing of waste materials as they are treated to obtain an injectable mass which may be injected in porous, underground formations. The plant according to this invention is treating waste materials including substantial portions of solid materials, and in particular drill cuttings, in connection with drill operations in connection with oil and gas wells in marine environments. The plant comprises a crushing machine (1) having two separate input ports (2 and 46), the first (2) primarily adapted for solid materials and the second (46) primarily for liquid materials, and produces a dispersion of diminutive solid particles dispersed in the liquid. The plant comprises possibly feedback means (23, 9 and 25, 35) for solid materials and circulating means (e.g. 31, 40) for the finished dispersion and also injected devices (32, 36, 37, 46).
(FR) Installation de traitement de déchets destinée à réaliser de manière sûre et permanente le dépôt des déchets pendant leur traitement, de manière à obtenir une masse que l'on peut injecter dans des formations souterraines poreuses. Ladite installation traite des déchets comprenant d'importantes quantités de matières solides, notamment les déblais de forage, en association avec des opération de forage visant à obtenir des puits de pétrole et de gaz en milieu marin. Elle comporte un concasseur (1) doté de deux orifices d'entrée séparés (2 et 46) dont le premier (2) est adapté principalement aux matières solides et dont le second (46) est adapté principalement aux matières liquides, et produit une dispersion de petites particules solides dispersées dans le liquide. L'installation peut éventuellement comporter des dispositifs (23, 9 et 25, 35) de réinjection de matières solides et des dispositifs (par exemple 31, 40) de mise en circulation de la dispersion finie, ainsi que des dispositifs d'injection (32, 36, 37, 46).
