堵水调剖剂对改善高含水油田的注水开发效果、 提高采收率发挥着至关重要的作用。综述了弱凝胶和颗 粒类油田传统堵水调剖剂的优缺点和应用现状， 介绍了植物油脂的特点及其在新兴领域如植物油聚硫橡胶、 植 物基生态润滑材料的研究进展、 应用推广及存在的问题， 提出通过硫化交联、 交内酯化和皂化水解等化学改性方 法将植物油脂及其工业副产物油脚用于油田堵水调剖领域。植物油脂和油脚价格低廉， 化学改性方法简便易操 作， 对岩心的封堵效果好， 在油田深部堵水调剖领域中的应用前景良好。图 2参 84

Water plugging and profile control agent played a crucial role on improving the effect of waterflooding development and enhancing oil recovery in high water-cut oilfield. The advantages and disadvantages and application status of traditional water shutoff agents like weak gel and granule materials were reviewed. The characteristic of plant oil and its research progress， application and existent problem in new fields such as plant oil based polysulfide rubber and ecological lubrication materials were introduced. The applications of plant oil and industrial by-product oil foot on water shutoff in oilfield through chemical modifications such as vulcanization， esterification and saponification hydrolysis were proposed. Plant oil and oil foot had broad application prospect on the field of deep water plugging and profile control due to low price， easy chemical modification and good sealing effect on cores
