CA 2510758

Method and apparatus for the cooling of drilling fluids (also referred to as mudcooler), characterized in that use is made of two heat exchangers, wherein the drilling fluid (or warm drilling oil) is led through the first heat exchanger and is cooled by a mixture of glycol and water, while the glycol/water mixture is circulated in a closed circuit through a second heat exchanger, whereby the glycol/water mixture is cooled by seawater.

La présente invention a trait à un procédé et un appareil pour le refroidissement de fluides de forage (également désigné refroidisseur de boue), caractérisé en ce qu'on utilise deux échangeurs thermiques, et en ce que le fluide de forage (ou l'huile de forage chaude) est amené à circuler dans le premier échangeur thermique et est refroidi par un mélange de glycol et d'eau, tandis que le mélange glycol/eau est circulé en circuit fermé à travers un deuxième échangeur thermique, permettant ainsi le refroidissement du mélange glycol/eau par l'eau de mer.
