摘　　要：石油是重要的战略储备资源,目前国内外很多油田已经进入到开发后期,水驱油藏含水率极高,因此研发合适的化学堵水调剖材料迫在眉睫。由于水驱开发加重油藏非均质性,部分储层条件十分苛刻,如储层温度高、地层水高矿化度及特定开发工艺对堵剂的特殊需求,现有的封堵材料已无法满足油田生产的需求。通过对国内外调剖堵水技术现状及存在问题进行系统分析,依据我国注水开发情况及需要,提出了堵剂的发展趋势,即充分考虑不同油藏开发后期堵水调剖实际需要,结合经济效益考量,以廉价高效、适应性强的堵剂研发为核心,开展相关施工技术及机理理论研究,实现对一些难于开发的油藏进行开发利用,使其转变为可采储量,对高效开发注水开发后期油田、丰富我国石油储备。Petroleum is an important strategic reserve resource. At present, many oil fields at home and abroad have entered the late stage of development, and water-flooding oil reservoirs have extremely high water cut. Therefore, it is urgent to develop suitable chemical water plugging and profile control materials. Because water flooding development aggravates the heterogeneity of oil reservoirs, some reservoir conditions are very harsh, such as high reservoir temperature, high salinity of formation water, and the special requirements of specific development techniques for plugging agents. The existing plugging materials can no longer meet the needs of oilfield production. In this paper, the current situation and existing problems of profile control and water shutoff technology at home and abroad were systematically analyzed, and the development trend of plugging agents was put forward based on the development and needs of water injection development in China, such as fully considering the actual needs of water plugging and profile control in the later development of different reservoirs, and combining the consideration of economic benefits,taking the research and development of cheap, efficient and adaptable plugging agents as the core, carrying out related construction technology and mechanism theory research to realize the development and utilization of some reservoirs,enriching my country’s oil reserves.
