摘要:

对国内外有机凝胶调剖堵水的研究成果进行了综述,从聚合物本体凝胶、有机硅凝胶、热/盐/pH 敏感性凝胶、
就地聚合凝胶以及聚合物微球五大类体系进行了阐述。介绍了各种体系的作用机理、优缺点和现场应用情况。其中
聚乙烯亚胺(PEI)交联凝胶体系有低毒、抗温、抗盐等许多优点,可用于恶劣油藏堵水作业。从化学调剖堵水技术发展
趋势来看,合成孔喉尺度匹配的各种功能性聚合物微球将是未来深部调驱技术的重点发展方向。在有机凝胶调剖堵
水方面取得了一定的研究进展,将对今后相关研究工作和现场应用具有参考价值和指导意义。

Abstract:

This paper gives an update review on the progress of researches on organic-gel used for water shutoff and conformance
control. Five kinds of popular gel systems such as bulk gel,organosilicon gel,thermosensitive/salt-sensitive/pH sensitive
gel,in-situ polymer gel and polymeric microsphere are included. This paper introduces the working mechanism,merits and
demerits and field application of each gel system. Polyethyleneimine(PEI)cross-linking gel system has advantages of being
low toxic,high-temperature and high salinity tolerant etc. This gel system can be used for water shutoff in hardness reservoirs.
From the tendency of water control of chemical methods,synthesizing various functional polymeric microsphere which can
match with pore throat will receive great attention in the next decades. This paper has achieved some research progress in
organic-gel used for water shutoff and conformance control,which can offer favourable reference for related work and field
application.
