Beschreibung
Zusammenfassung:	The present invention generally relates to methods and friction-reducers for decreasing the friction of a fluid. More specifically, the method comprises contacting a friction-reducer to reduce the friction of a fluid flowing in a conduit. The friction-reducer comprises an emulsion polymer, comprising polyanion, polycation, and polynonionic monomers, and a highly concentrated salt solution. La présente invention concerne d'une manière générale des procédés et des réducteurs de forces de frottement permettant de diminuer les forces de frottement d'un fluide. Plus particulièrement, le procédé consiste à mettre en contact un réducteur de forces de frottement pour réduire les forces de frottement d'un fluide circulant dans une conduite. Le réducteur de forces de frottement comprend un polymère en émulsion, comprenant un polyanion, un polycation, et des monomères poly-non-ioniques, et une solution saline hautement concentrée.
