The Application of PI Decision Technology on Water Plugging and Profile Control in Oilfield

 HuoShaoShan Oilfield is characterized by low permeability and fully-developed fracture. Consequently,poor effect is obtained on every single well while the conventional water plugging and profile control technology is used. So, PI decision technsology is used and H3 layer is taken as pilot area. In the course of it, different projects are employed according to development characteristics in every region so that tangible effect is achieved and the problem of water plugging and profile control in the oilfield is solved.
