The present invention provides methods of treating subterranean zones penetrated by well bores in primary well cementing operations, well completion operations, production stimulation treatments and the like. The methods are basically comprised of introducing into the subterranean zone an aqueous well treating fluid comprised of water and a water soluble polymer complex fluid loss control additive.
La présente invention concerne des procédés permettant de traiter des zones souterraines dans lesquelles des puits de forage sont ménagés, pendant des opérations de cimentation de puits, des opérations de conditionnement de puits, et lors de traitements visant à stimuler la production, ou pendant toute autre opération. Les procédés décrits dans cette invention consistent, fondamentalement, à introduire dans la zone souterraine un fluide de traitement de puits aqueux composé d'eau et d'un additif de régulation de la perte de fluide complexé avec un polymère hydrosoluble.
