ABSTRACT

After water flooding reservoir has been carried out for a certain period of time, the contradiction between plane and vertical becomes increasingly prominent, rational allocation of water injection is becoming more and more important. The dynamic balance of water injection and oil recovery system is analyzed and combined with dynamic and static data. It is suggested that the split coefficient method be used instead of the traditional KH or H method, calculation of rational injection water volume for injection, strive to achieve precise water distribution.
