油田开发后期的强化注水模式探讨

Discussion on the Enhanced Water Injection Mode in the Late Stage of Oilfield Development

油田开发后期,注水开发的结果导致高渗透油层见水或者被水淹,需要实施堵水的技术措施,才能恢复高渗透层的生产能力。而对于低渗透层的注水,需要强化注水,才能提高低渗透层的水驱开发效率,提高油井的生产能力,满足油田开发后期的产能要求。

At the later stage of oilfield development, the result ofwaterflooding development has led to the seepage or flooding of high-permeability oil layers and the implementation of technical measures for water shut-off to restore the production capacity of high- permeability layers.For water injection in the low-permeability layer, it is necessary to intensify the water injection in order to improve the waterflooding development efficiency of the low-permeability layer, increase the production capacity of the well, and meet the production requirements of the later stage of oilfield development.
