摘　　要：针对高温高盐油藏增加可采储量的要求,开展了有机交联聚合物驱油技术研究。通过矿场单井试验,评价了有机交联聚合物驱油体系在高温高盐油藏中的地下成胶性能、注入性能及应用效果。单井试验现场动态反应良好,注入压力上升了3MPa,流动阻力增加,吸水剖面得到改善,表明有机交联聚合物驱是适用于高温高盐油藏的一种提高采收率技术。The technology of organic cross-linked polymer flooding is studied according to the need of recoverable reserves increase in high temperature and high salinity oil reservoirs. The injection performance and gelation performance in formations and application effect of the organic cross-linked polymer system are evaluated by field test of single well. The field behavior is good : the injection pressure increased by 3MPa,and the flow resistance increased, the injection profile was improved as well. Therefore the system could be used to enhance the oil recovery in high temperature and high salinity oil reservoirs.
