Oilfield Water Injection System Simulation, Control, Optimization And Efficiency Analysis

Water-flooding as an important way to oil exploitation used by many oilfields in our country . Its purpose is to make up the energy in oil reservoir and displace oil to the wellbore ,and the water injection system take an important role in Water-flooding system.This paper using reversal method to calculate the nodal point pressure, flow rate and pressure drawdown of pipeline in the water injection pipeline network; Analyzing the condition of pumping in the centrifugal water injection system and pressure boosting water injection system, make sure the plan for pumping ; Calculating the efficiency of water injection system and Presenting the methods for enhancing the efficiency of water injection system; Optimizing design for the whole water injection pipeline network of oilfields; Advancing the mathematical model of optimization design problem for water injection pipeline network improvement.
