摘　　要：高温高盐的地层环境在调驱时,容易导致调驱体系失效,并且体系的有效期短。为此经过大量的实验研究研制出了针对高温高盐油藏的胶态分散凝胶调驱体系。文章主要从流动性能、注入性能、封堵性能等方面,对该体系的性能进行评价,以确保该体系能够切实解决高盐油藏在开发中面临的困难。When using profile control and flooding system, high temperature and salinity environment could easily lead to gel strength decreased of profile control and flooding system, also the system is valid short. A colloidal dispersion gel for high temperature and salinity reservoirs was developed by a large number of experiments. In this article, performance evaluation of the system was done from flowability, injectivity and sealing performance etc, to ensure that the system can effectively solve the difficulties in developing high temperature and salinity reservoirs.
