摘　　要：胜利海上油田已成为胜利油田产量稳定和接替的重要阵地,但随着注水开发的深入,有限的海工设施寿命和处理能力与较低的采油速度的矛盾逐渐加剧,海上采油成本不断上升,盈利空间逐渐下降。三次采油是提高采油速度和采收率的有效技术手段,但受到海上特殊生产环境制约,大规模推广的适应性需要慎重评价。文章通过对比分析聚合物和弱凝胶驱油技术在海上应用的优缺点,提出适应胜利海上油田特点的弱凝胶调驱方案。Shengli offshore oilfield plays an important part in stabilizing and also will be the main source of oil production.However,with more water flooding development were implemented,the cost of oil recovery is constantly rising,and the profit space is gradually decreasing,which is caused by the contradiction between the limited life,treatment capacity of marine engineering facilities and the low oil recovery rate.Tertiary oil recovery is an effective technical means to improve oil recovery rate and recovery ratio,but it is restricted by the special offshore production environment,so the adaptability of large-scale promotion needs cogitate evaluation.In this paper,the advantages and disadvantages of polymer flooding and weak gel flooding technology in offshore oilfield are analyzed and compared,and a weak gel flooding scheme adapted to the characteristics of Shengli offshore oil field is proposed.
