聚合物凝胶调剖技术是油田改善后期注水开发效果、保持稳产的有效手段。本文通过一系列单因素变量实验研究了多个因素对聚合物凝胶调剖剂的影响，从而确定了适合石南4井区头屯河组油藏的调剖剂配方并进行了性能评价。结果表明：在单因素变化情况下，聚合物凝胶调剖剂成胶强度随着聚合物、交联剂、稳定剂的浓度的增大而增大，随着水质矿化度的浓度增大而减小；成胶时间随着聚合物、交联剂、水质矿化度的浓度增大而减小，随着稳定剂浓度的增大而基本无变化。成胶强度随着老化时间、温度、剪切强度的增大而减小。随着调剖剂注入量的增大，阻力系数和残余阻力系数而逐渐增大，而且二者差距幅度加大；封堵率先缓慢上升，后快速上升，最后趋于平缓。针对石南4井区头屯河组油藏，建议采用的调剖剂配方为：聚合物（2500万相对分子量）浓度1500 mg/L、交联剂0.3%、稳定剂0.1%、水质矿化度26 g/L；注入方式为：前置段塞0.15 PV（孔隙体积）+主体段塞0.25 PV+保护段塞0.1 PV。
The Polymer Gel Profile Control technology is one of the effective way to improve the water injection efficiency and stabilize the reservoir production. In this paper, a series of single factor variable experiments are carried out to study the effects of a number of factors on the polymer gel profile control agent and the polymer gel profile control agent is developed and evaluated for no.4 well area reservoir of the Shinan Oilfield. The results show that in the univariate preconditions, the gel strength increases with the increase of the concentrations of the polymer, the crosslinker, and the stabilizer and decreases with the increase of the concentration of the salinity; the gel time decreases with the increase of the concentrations of the polymer, the crosslinker, the salinity and is essentially unchanged with the variation of the concentration of the stabilizer. The gel strength decreases with the increase of the aging time, the temperature, and the shear strength. The drag coefficient and the residual resistance factor increase with the increase of the injection volume of the polymer gel profile control agent, and the gap between the drag coefficient and the residual resistance factor increases with the increase of the injection volume of the polymer gel profile control agent. The plugging rate rises slowly firstly, then rapidly and remains stabilized at last. The polymer with the 25 million molecular weight of 1500 mg/L, the crosslinker of 0.3%, the stabilizer of 0.1%, the salinity of 26g/L, the injection volume of 0.25 PV of the polymer gel profile control agent and the pre-slug of 0.15 PV + the main slug of 0.25 PV + the postpad slug of 0.1 PV of the injection mode are recommended for no. 4 well area reservoir of the Shinan Oilfield.
