中文摘要:
      针对海上油田聚合物驱井组间受效差异大、海上平台对产出聚合物处理能力有限及调整挖潜缺少理论依据等问题。从室内实验、数值模拟及油藏工程方面入手研究,创新形成了聚合物驱流度控制差异化,产聚浓度合理预测和聚驱合理注采井距确定三项关键技术。将该关键技术应用于矿场实践后,有效提高了聚合物药剂利用率并使产油量增加;降低了聚合物产出剂量超过平台处理能力风险;增强了注聚合物区域调整挖潜效果。对海上同类聚合物驱油田改善开发效果具有借鉴意义。
英文摘要:
      In response to issues such as significant differences in efficiency between polymer flooding well groups in offshore oilfields, limited processing capacity of produced polymers by offshore platforms, and a lack of theoretical basis for adjusting and tapping potential. Through research in physical experiments, numerical simulations, and reservoir engineering, three key technologies have been innovatively developed: differential flow control for polymer flooding, reasonable prediction of polymer concentration, and determination of reasonable injection production well spacing for polymer flooding. After applying this key technology to mining practice, it effectively improves the utilization rate of polymer reagents and increases oil production; Reduced the risk of polymer production doses exceeding the platform"s processing capacity; Enhanced the adjustment and potential tapping effect of polymer injection areas. It has reference significance for improving the development effect of similar offshore polymer flooding oilfields.
