摘要
可动凝胶调驱是高含水老油田大幅度提高石油采收率的重要技术之一。在大量资料调研和实验结果分析基础上,从技术发展的角度,较为系统地总结了可动凝胶体系的发展现状。新老凝胶体系的对比研究指出,可动凝胶体系利用自身的选择性封堵大孔道、克服贾敏效应和"变形虫"的独特特点,可以在油藏深部实现"封堵—突破—运移—再封堵"的驱油过程,达到"远调长驱、间歇调驱"的持续增油效果。同时指出,可动凝胶调驱技术在新体系的评价标准、机理研究及描述、数值模型及软件研制以及相关配套技术集成应用等方面有待继续深化和完善,而这些方面也是可动凝胶调驱技术的未来发展方向。
Movable gel profile controls is one of the important technologies in enhancing oil recovery in old oil fields with high water cut.In this paper, based on large amounts of data research and analysis of the experimental results, from a technical development point of view,a more systematic summary of the movable gel system current development situation has been made. The comparative study of old and new gel system shows that movable gel system can bock large pores using its own select,overcome the Jamin effect,and ' Amoeba' unique features, which can achieve ' closure- Breakthrough-migration-and then plugging' of the displacement process in the deep reservoir , to achieve ' far transfer a long drive, Intermittent Flooding' effect of the continued increase of oil. Also it pointed out that Movable gel profile control technology in the new system need to be deepen and perfect in the aspects of evaluation criteria, mechanism and description, numerical model and the software development and relevant supporting technologies such as integrated application,which is also available in the future development of movable gel profile control technology.
