摘要
为改善某低渗透油田的水驱开发效果,开展了聚合物强化氮气泡沫调剖提高采收率研究.根据该油田的地质油藏条件,建立典型地质概念模型,地质模型能够比较完整地反映地层静态状况和井网条件.对聚合物强化泡沫调剖注采参数进行了优化设计.研究结果表明,聚合物强化氮气泡沫调剖最佳注采参数为:聚合物分子量为800万,聚合物浓度为1000mg/L,最佳泡沫剂浓度为0.25%(质量分数),气液比为1:1.
In order to improve the effecl of low permeability oilfield water flooding devel- opment, and carry out the study of polymer enhanced foam profile to improve oil recovery. According to the field geological and reservoir conditions, the establishment, of typical geolog- ical conceptual model of geological model can more fully reflect the formation conditions and well pattern static conditions. On polymer enhanced foam profile control injection-production parameters were optimized. The research results show that polymer enhanced foam profile control best injection-production parameters as follows： the polymer molecular weight is 8 mil- lion, polymer concentration of 1000 mg/L, the best concentration of foaming agent is 0.25% （mass fraction）, gas liquid ratio is 1：1.
