Process to improve hydrocarbon recovery by decreasing injection solution viscosity and improving solution screen factor |
摘要 |
An aqueous solution comprised of partially hydrolyzed polyacrylamide and an ethoxylated alcohol, is injected into a subterranean hydrocarbon bearing formation via an injection well followed by injection of a drive fluid. The solution displaces hydrocarbons from formation pores and the drive fluid pushes the displaced hydrocarbon and the aqueous solution toward a production well enhancing hydrocarbon production. The ethoxylated alcohol decreases solution viscosity and increases solution screen factors resulting in improved injectivity, improved mobility control and ultimately improved hydrocarbon production.
