摘　　要：通过文献检索并综合油田实际生产情况,介绍了凝胶性能评价指标及具体的评价方法,评价指标包括胶凝时间、成胶强度、长期热稳定性、抗剪切性、耐盐性、抗酸碱性、封堵效果、微观表征。针对凝胶的地上地下成胶性能进行了较为全面的评价,为凝胶在室内和油田现场评价提供理论指导。The evaluation indexes and specific evaluation methods of gel properties were introduced,including gel time,gelling strength,long-term thermal stability,shear resistance,salt resistance,acid and alkali resistance,plugging effect and microscopic characterization.The gel-forming properties of gels above ground and below ground are evaluated comprehensively,which provides theoretical guidance for the evaluation of gels in laboratory and field.
