聚合物井网投产初期，对特高含水油井采取暂时关井、高含水饱和度油层实施分步射孔的措施，以获得良好的驱油 效果和最佳的经济效益。本文根据聚合物流体性质和在油层中的渗流特征，考虑了油层中聚合物溶液浓度随时间和位置 的变化，及聚合物粘度、油层渗透率的变化，建立了非均质不规则井冈条件下聚合物前缘位置和油水井动态预测模型，定 量分析了高含水井开井和高含水层补孔时机对聚合物前缘推进速度、水井注入压力、聚合物驱油效果的影响，给出了聚驱 条件下高含水井层的合理打开时机；在大庆采油－厂北－区ＰＩ组油层聚驱井网进行了实际验证和应用。
In the initial stage of the production of polymer well network, the step-perforation and high-water saturation reservoirs are applied to ultra-high water cut wells to implement step-perforation measures to obtain good oil displacement effect and the best economic benefits. In this paper, according to the properties of polymer fluid and the seepage characteristics in the oil layer, taking into account the change of concentration of polymer solution with time and position in the oil layer, the viscosity of polymer and the permeability of oil layer, Polymer front position and oil-water well dynamic prediction model, quantitative analysis of open-hole high-water wells and aquifer recharge timing of the polymer front advancing speed, water injection pressure, polymer flooding effect, given Reasonable opening timing of high-water-bearing well under the condition of poly-flooding, and actual verification and application of poly-flooding well in PI reservoir of Daqing oil production-plant north-district.
