| titleOfInvention | Hydrocarbyl phenol polyether bisbenzene sulfonate oil flooding surfactant, composition and preparation method and application thereof |
| abstract | The invention relates to a hydrocarbon-based phenol polyether bisbenzene sulfonate oil flooding surfactant, a composition and a preparation method and application thereof, and mainly solves the problem of low oil displacement efficiency under high temperature and high salt conditions in the prior art containing surfactants. The problem. The present invention adopts a kind of surfactant for oil displacement which improves the recovery of crude oil. 2 is independently selected from any one of alkali metals and alkaline earth metals, when M is an alkali metal, n is 1, when M 1 is an alkaline earth metal, n 1 is 0.5, when M 2 is an alkali metal, n 2 is 1, when When M 2 is an alkaline earth metal, n 2 is 0.5, R is a hydrocarbon group of C 4 to C 30 , x=1 to 20, y=0 to 20, which can better solve this problem and can be used for enhanced oil recovery in oil fields in production. |
