A New Production Splitting Method Based on Phase Permeability and Water Displacement Tests

For multi-zone combined oil production reservoir, the production of each small layer is the basis and basis of adjusting development plan, comprehensive potential exploitation and enhanced oil recovery. The existing methods have disadvantages such as single consideration factor, large influence of test data and long research period. Considering the injection well and production well as a whole, based on the inherent water drive characteristics and facies permeability characteristics of the reservoir, based on the small layer stratified data and production dynamic data, and restricted by the stratified test data, the vertical and plane injection water volume is divided. Combined with the injection multiple of the small layer, the water content, liquid production and oil production of the small layer are obtained. The liquid and oil of each small layer are added together and compared with the actual production data. The results show that the splitting results of this method are in better agreement with the actual production, and can reflect the output of each layer more truly. It has the characteristics of high accuracy, strong operability, and stronger field guidance.
