A universal model for water injection system is presented. It can be applied to any water injection system in oil fields. Universal calculation method of water injection system is given based on this model. A software package is programmed based on the method above. It can be applied for modelling, calculation and simulation of large water injection systems, and it can also be applied to closed control of water injection system if there are hardwares needed for control in the water injection system. The modelling method and the calculation method are also applied to any incompressible fluid networks, for example, oil collecting and transporting network.
