Abstract: front page image
(EN)The invention is directed to long lasting crosslinked water-soluble swellable polymers, methods for making same, and their uses. More particularly, the invention relates to a composition comprising expandable polymeric particles having cationic sites as well as labile crosslinkers and stable crosslinkers, said particle mixed with a fluid. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric particles are injected into a target zones in the reservoirs and when the heat and/or pH of the reservoir cause degradation of the labile crosslinker and when the particle expands, the cationic sites in the polymer adsorb to the rock in the formation, thus diverting water to lower permeability regions and improving oil recovery. However, many other uses are possible.
(FR)L'invention porte sur des polymères gonflables, solubles dans l'eau, réticulés et de longue durée, sur des procédés pour les fabriquer et sur leurs utilisations. Plus particulièrement, l'invention porte sur une composition comprenant des particules polymères expansibles, ayant des sites cationiques, ainsi que des agents de réticulation labiles et des agents de réticulation stables, lesdites particules étant mélangées à un fluide. Une utilisation particulièrement importante est une utilisation en tant que fluide d'injection dans la production de pétrole, où les particules polymères expansibles sont injectées dans des zones cibles se trouvant dans les réservoirs et, quand la chaleur et/ou le pH du réservoir provoquent une dégradation de l'agent de réticulation labile, et quand la particule se dilate, les sites cationiques se trouvant dans le polymère s'adsorbent sur la roche dans la formation, permettant ainsi de dévier l'eau vers des régions à perméabilité plus faible et d'améliorer la récupération du pétrole. Cependant, de nombreuses autres utilisations sont possibles.
