高温油藏交联聚合物凝胶系统研究进展

Research progress of cross-linked polymer gel system in high temperature reservoir

聚合物凝胶处理方式作为使用广泛使用的调剖堵水方式,提高采收率的重要手段。在深部储层中,受温度的限制,常规的聚合物凝胶体系已不再能够满足现场需求。因此从凝胶体系的多角度出发,探讨了增强凝胶体系的高温稳定性与强度的方式与机理。

The polymer gel treatment method is an important means to improve the recovery efficiency by using profile control and water shutoff.In deep reservoirs,due to temperature limitations,conventional polymer gel systems can no longer meet field requirements.Therefore,the method and mechanism of enhancing the high temperature stability and strength of the gel system are discussed.
