摘　　要：某一油田为普通稠油油田,具有非均质性强以及地层水矿化度高等特点,油田经聚合物驱后,储层的非均质性进一步加强,注水突进也更加严重。针对这一问题,开展了弱凝胶体系深部调驱技术研究。通过室内体系评价与物理模拟等方式,对弱凝胶体系的理化性能和驱油效率等方面进行了优化评价。与注聚合物相比,聚合物驱后,继续进行弱凝胶调驱,可以提高采收率9.49%。弱凝胶调驱技术在普通稠油油田具有很好的应用前景。An oil field is a heavy oil field with characteristics of heterogeneity and high salinity.After the polymer flooding,the reservoir heterogeneity was further strengthened and water flooding was more serious.Aiming at the problem,the deep profile control and flooding technology of weak gel system was studied.The physical and chemical properties and displacement efficiency of weak gel system were optimized through indoor system evaluation and physical simulation.Compared with polymer injection,the oil recovery can be improved by 9.49%.Weak gel profile control and flooding technology has good application prospects in heavy oil fields.
