Abstract: Gel particles re crosslinked profile control technology is that when injecting gel particles profile control agent, injecting cross-linked polymer, so that the two materials can be combined in the formation to enhance gel particles effect. Based on the laboratory test, the cross-linked polymer matching gel particle profile control agent has been identified to achieve the best results. In 2009,this technology has been applied in 6 wells Wenmingzhai oilfield, with cumulation of 1,483 ton oil, which increased oil production significantly.
