摘要
聚合物驱是油田提高原油最终采收率的重要手段之一。结合孤岛油田的相关资料,利用油藏数值模拟软件CMG,建立聚合物驱模型,针对影响聚合物驱效果的三个重要参数:注入时机、注入速率以及注采比进行研究。通过改变三个参数,探究日产油量、日产水率以及原油最终采收率的变化规律。模拟结果表明,在合理的成本范围内,注入聚合物的时机越早越好;提高聚合物注入速率时,原油最终采收率有下降趋势;注采比为1时,驱油效果达到最佳,对实际生产起到积极的指导作用。
Polymer flooding is one of the important methods of enhancing oil recovery efficiency. A polymer flooding model is built using the reservoir numerical simulation software CMG, which is based on the relevant information of Gudao oilfield. Three important parameters that affect the effect of polymer flooding are studied, with the injection time, injection rate and injection-production radio included. Research the regulation of oil rate, water cut and oil recovery by changing three parameters. The simulation results show that injection time should be earlier as much as possible on the basis of reasonable costs, the recovery efficiency has the tendency to decrease when improving the injection rate of polymer flooding and the oilfield development can be better when the injection-production ratio is 1, which have a positive effect on actual production.
