油田开发后期的强化注水研究

Study on Water Injection Intensification in the Later Stage of Oilfield Development

当油田的开发注水工作进入到后期阶段时,会使得整个油井的含水量不断增长,产量递减也在逐渐加快,注水井以及采油井之间的状态发生变化,一定要通过稳油控水的技术手段,使油井本身的生产能力保持稳定的状态。对渗透性比较低的油层进行注水强化工作,也提高渗透的油层的注水效果,对油层剖面进行实施监控,选择不同的注水方式,调整注水方案,这样才能够更好的提高剩余油的开发效率,达到油田的产能标准,实现油田经济效益的最大化。

When the development and water injection work of the oilfield enters the later stage,the water content of the whole oil well will increase continuously and the production decline will be accelerated gradually.The state between the water injection well and the oil production well will change.It is necessary to keep the production capacity of oil wells stable by means of stabilizing oil and controlling water.Water injection intensification for low permeability reservoirs can also improve the water injection effect of high permeability reservoirs.Monitoring reservoir profile,selecting different water injection methods and adjusting water injection schemes can better improve the development efficiency of remaining oil,meet the oilfield productivity standards,and maximize the economic benefits of the oilfield.
