For the past decades, long-term water flooding processes have led to water channeling in mature reservoirs, which is a severe problem in oilfields. The development of better plugging ability and cost-effective polymer gel is a key aspect for the control of excess water production. Research on polymer gel applicable in a heterogeneous reservoir to plug high permeable channels has been growing significantly as revealed by numerous published scientific papers. This review intends to discuss the polymer gel techniques from innovations to applications. The related difficulties and future prospects of polymer gels are also covered. Developments of polymer gels to resist temperature, early gel formation, synergistic mechanisms and influence of pH, high salinity are systematically emphasized. The review provides a basis to develop polymer gels for future applications in oilfields to meet harsh reservoir conditions. It will assist the researchers to further develop polymer gels to improve the oil recovery from mature reservoirs under economic conditions to meet the requirements of future oilfields.
在过去几十年里，长期的水驱过程导致了成熟油藏中的水窜，这是油田中一个严重的问题。开发具有更好封堵能力且经济高效的聚合物凝胶是控制过量产水的关键方面。正如众多已发表的科学论文所揭示的那样，适用于非均质油藏以封堵高渗透通道的聚合物凝胶的研究一直在显著增加。本综述旨在讨论聚合物凝胶技术从创新到应用的情况。还涵盖了聚合物凝胶的相关困难和未来前景。系统地强调了聚合物凝胶在抗温、早期凝胶形成、协同机制以及pH值、高盐度影响方面的发展。该综述为开发聚合物凝胶以满足未来油田恶劣油藏条件下的应用提供了依据。它将帮助研究人员进一步开发聚合物凝胶，以便在经济条件下提高成熟油藏的采收率，满足未来油田的需求。
