Abstract

Profile control is a method to plug high-permeability layer from water injection well. It can improve injection profile of water injection section. Water shutoff is a method to plug high-permeability layer from production well. It can reduce water production in production wells. Both methods can plug high-permeability layer and divert the injected water entering the low permeable layer. So the sweep efficiency of injected water is promoted, and the oil recovery is enhanced. In this chapter, the chemical agents used in profile control and water shutoff are introduced in detail. The chemical formula and application scope of various chemical agents are listed. Meanwhile, the importance of profile control and water shutoff is described; rough categories and their enhanced oil recovery mechanism of both methods are discussed.
