摘要
聚合物驱油技术在胜利油区的工业化推广应用取得了较好的增油降水效果,经济效益显著。采用数值模拟和经济评价相结合的方法计算了不同油价下胜利油田聚合物驱单元的经济界限指标,研究了胜利油区聚合物驱的技术和经济潜力。认为:聚合物驱最佳用量与油价密切相关,低油价下,低聚合物用量的经济效益好,高油价下,高聚合物用量的经济效益好,在目前高油价状态下,聚合物驱单元应该进一步增加用量,延缓后期含水上升速度,提高聚合物驱的总体经济效益;后续水驱单元二次注聚的潜力较小;胜利油区适合聚合物驱的四类资源较少,聚合物驱风险较大;三类资源比较丰富,但常规聚合物不适合三类高温高盐油藏,需要进行耐温抗盐聚合物和聚合物加合增效体系攻关研究,在先导试验取得成功的基础上,可成为下步聚合物驱的主阵地。
Numerical simulation and economic evaluation were used to study the economic limits under different oil prices and the potential of polymer flooding in Shengli Oilfield. The optimum polymer amount is closely related to the oil price. In terms of economic effectiveness, low oil price requires small amount of polymer, and high oil price requires larger amount. In the present high price, the potential of increasing polymer amount is great in the polymer flooding units. The potential is low in the follow-up water flooding units. There is no potential in the fourth reservoirs for its bad interconnection and pore and void growing. The partially hydrolyzed polyacrylamide （HPAM） is unfit in the rich third reservoirs of high temperature and high salinity. By the further study of polymer with temperature resistance and salt tolerance and polymer with one or more types of special chemicals, the polymer flooding technology would be used in the third reservoirs if pilot tests succeed.
