摘　　要：为解决油田非均质性强、水驱效果差问题,大港油田持续多年开展了深部调剖技术研究与推广应用,在调驱体系评价研究、调剖充分程度判别研究、水驱状况的快速判别方法研究以及工艺设计优化等方面取得了一系列成果,规模推广应用取得了显著效果,共计推广应用深部调驱技术640余井次,有效率80.3%,累计增油44.1×104t,研究结果表明:深部调驱技术有效地改善了高含水油田注水开发效果,成为目前大港高含水、高采出程度油田深化挖潜的主体工艺之一。Fesearch and promotion of deep profile control technology has been launched for many years in Dagang Oilfield to solve the problems of strong heterogeneity and poor water flooding effect. A series of achievements have been made, such as evaluation of profile control agents, decision for occasion of profile control, rapid identification for water flooding situation and process design optimization. These technologies were applied all in scale and remarkable results have been achieved. Deep profile technique was used for more than 640 well times and the efficiency came to 80.3%. 44.1×10^4t tons of oil in total has been recovered. The results show that the deep profile control technology improved the development of oil field effectively and is now one of the most potential technologies for oil recovery in Dagang Oil Field of high water cut and high degree of recovery stage.
