The invention is a novel drilling fluid additive comprising particles of elastomer which are capable of swelling upon contact with a hydrocarbon fluid. The swelling of the elastomer is gradual, allowing the elastomer to reach the lost circulation zone before significant swelling occurs. Once in the lost circulation zone, the polymer expands sealing off the lost circulation zone. A method for preventing drilling fluid loss is also provided.
L'invention concerne un nouvel additif de boues de forage contenant des particules d'élastomère qui peuvent gonfler suite à un contact avec un fluide d'hydrocarbures. Le gonflement de l'élastomère est graduel, ce qui permet à l'élastomère d'atteindre la zone de circulation perdue, avant qu'un gonflement important ne se produise. Une fois dans la zone de circulation perdue, le polymère se dilate et ferme donc hermétiquement la zone de circulation perdue. Cette invention a aussi trait à un procédé de prévention de perte de boues de forage.
