Study of Prediction and Simulation of Flooding System Modification in Oil Field

Abstract

The prediction model of water injection rate has been built in this paper. The rate of injection water is a function of oil yield and synthetic moisture content among predicting process. The model is calculated by LS method. Combining real geology conditions with real flooding well network, the flood pattern modification sketch can be given both to old and new development block. Injection well quantity, injection station quantity and pipe network modification have been included in this sketch. According to the prediction rate of water injection and the modifications scheme, the computer simulation experiment can be completed for different operating sketch. The iterative method was adopted to find the solution of simulation experiment, the conditions of flood pattern, injection stations and pipe network have been expressed in operating parameter. At last, the correction of method is validated by practical data of an oil field.
