摘　　要：以侏罗系低渗透高矿化度油藏为对象,总结了近年来油田进行聚合物驱油试验的经验与教训,根据目前国内外聚合物弱凝胶驱油技术进展,结合研究区的地质特征和开发状况,研制出适用于侏罗系高矿化度低渗透油藏的聚合物弱凝胶驱油体系,并进行了现场试验。现场试验表明:聚合物弱凝胶体系适用于高矿化度低渗透油藏,能有效减缓低渗透油藏产量递减,降低含水,提高采收率。Based on the low permeability and high salinity oil reservoirs of Jurassic,this paper summarizes the experiences and lessons of polymer flooding experiments in recent years. According to the present technology in weak polymer gel flooding at home and abroad,and based on the geologic reservoir features and current status of exploitation,a weak polymer gel flooding system which meet the situation of low permeability and high salinity oil reservoir of Jurassic is developed,and the system performes well in the field experiment. The results showed that weak polymer gel flooding system is suitable for low permeability and high salinity oil reservoirs;it can slow down the descending,reduce the water ratio and enhanced oil recovery.
