To know the production status of the reservoir in water injected fields, we must take effective measures to improve our development level and provide reliable accumulated injected-water volume for reservoir description. This article gives the dynamic division equation of accumulated injected-water volume in absence of the water injection profile information based on the filtrational theory. Then we study the method about how to take the values of the involved parameters. Application results in situ prove that this equation can provide more accurate accumulated injected-water volume of beds, and meet the development needs.
