The research of numerical simulation in Wuliwan oilfield water injection system

This paper studied the efficiency of the oilfield water injection system by using the water injection system theory, fluid mechanics theory, and graph theory and optimization design technology. According to the actual conditions, the paper established the mathematical model of Wuliwan oilfield pipe network. Based on the actual data of production, energy distribution of oilfield water injection system was analyzed. Making the unit energy consumption of water injection lowest as the goal, solves through this mathematical model obtain the optimized pumping plan, thus the reasonably distribution of flooding energy, the enhancement pipe network system efficiency, reduces the system energy consumption. It supplies one scientific support for the Wuliwan oilfield to improve the level of flooding system management.
