Abstract
In the 20 years of waterflood development in the Niuxintuo oilfield, the contradiction between water injection in plane and interlayer is prominent, so it is urgent to adjust the injectivity profile, especially for depth profile control.Using the existing profile control agent system to improve the profile control, the effect of gel formation is poor, and the profile control effect is not satisfactory.It has been found that the presence of dissolved oxygen in the profile control agent is the main factor affecting the effect of profile modification.The site provides the polymer, crosslinking agent and water samples, the use of commonly uses deoxidant on Niuxintuo oilfield profile control agent to improve the effect to carry out a series of laboratory experiments.The results show that sodium benzoate and hyposulphite for improving the effect of gumforming compound have certain effect.关键词
