GLOBAL OPTIMIZATION OF THE PRORATION PRODUCTION OF THE OIL FIELD STIMULATION TREATMENTS

The main purpose of production proration is to distribute the total oil increment task to stimulation treatments optimally. The stimulation treatments are screened and classified, and the benefit-cost model of every type of stimulation treatments is established by the integration transformation. A multi-variable, multi-factor, and multi-goal production proration model is created. The optimal solution equation is gained by the least-squares-method based on the extremum theory of nonlinear functions. The scan method to find the optimal solution is given out. The automatic production proration to oil field stimulation treatments is realized using a computer and is applied to Zaoyuan Oilfield. It’s proved that the method is simple, the result is dependable, and the economic effect is notable.
