摘要
油田注水开发方式的调整导致注水井配注水量发生改变,使得管网系统在供水能力充沛的情况下,注水井的供水量与需水量不再匹配;同时注水系统有较强的整体性,改变一个注水站的运行参数经常会引起整个系统能量耗散的变化,使各注水站的注水负荷发生显著变化。针对上述问题,结合油田典型多区块注水系统现有的水井泵压,监测注水区块压力边界,通过连续比较得到某一区块的压力变化,进而掌握该区块注水量的变化,逆向查找压力波动和水量缺失原因,由此合理调用水资源,指导优化开泵方案,为油田降本增效提供有力的数据及决策支撑。
When the water injection development mode in oilfields is adjusted, the water injection quantity of the injection well will be changed, so that when the water supply capacity of the pipe net-work system is sufficient, the water supply and water demand of the water injection well will no longer match each other. At the same time, the water injection system has strong integrity, so changing the operating parameters of a water injection station often leads to the change of the energy dissipation of the whole system and makes the water injection load of each water injection station change significantly. In view of above problems and combining with the existing pump pressure of the water well in the typi-cal oilfield multi-block water injection system, the pressure boundary of the water injection block in monitored. Through continuously comparing the change of the pressure of a block is got, and then the change of the water injection amount in the block can be mastered. Reverse lookup of causes for pressure fluctuation and water amount lack can help to reasonably allocate water resource and guide op-timized pump opening scheme,which provide useful data and strong support for lowering cost and in-creasing benefits in the oilfield.
