Abstract
Currently, water flooding is the main method to maintain reservoir pressure and improve oil production in many oilfields. A calculation procedure is developed based on the Buckley-Leverett theory (φ function) to determine the reasonable water injection rate, which directly improve the effectiveness of field development. φ function (the derivative of water fractional flow with respect to water saturation) is the reciprocal of PV number, which relates to the swept area, effective reservoir thickness, water cut and cumulative water injection. Considering all these factors, the proposed method can ensure the rationality of water injection rate.
