摘　　要：根据稠油注水开发的海1块储层特征、原油物性和注入水性进行室内配方筛选,并对成胶性能各种影响因素程度进行评价,筛选出了稠油注水的调驱体系。运用提高采收率技术的理论和经验公式,结合现场动静态资料,对调驱措施效果、开发水井改善情况、注水利用率及提高采收率等情况进行了综合研究。调驱后水驱动用程度和水驱采收率均得到了提高,为油田转换开发方式、提高油田采收率提供了一定的借鉴。The formula systems of profile control and oil displacement have been screened according to reservoir characteristics, oil property and injected water quality of Hai 1 heavy oil reservoir developed by water flooding. The influencing factors of gel performance are evaluated. Field tests have been performed for typical well groups to adjust the formula system and injection process according to practical production conditions by following the principle of reducing risk and ensuring success. Comprehensive evaluation has been made for the effect of profile control and oil displacement, the improvement of water well conditions, and the effectiveness of water injection, etc., by using EOR theory and empirical equations as well as dynamic and static data. The result shows that the producing degree and the recovery factor of water flooding have increased after profile control and oil displacement. This study provides reference to converting oilfield development strategy and improving oil recovery.
