摘　　要：针对胜利油区孤岛油田西区油藏条件和现场实际 ,对不同水解度的聚合物在地层温度下经过长期相互作用引起的粘度、水解度、浓度以及复合体系动态界面张力变化规律进行了室内研究。研究表明 ,在一定的地层条件下 ,不同水解度的聚合物经过长期水解均趋于同一水解平衡值 ,在 10 %～ 40 %水解度范围内 。Laboratory study is done for the change rules of viscosity, degree of hydrolysis, concentration and dynamic interfacial tension of combination system caused by long?term interaction at formation temperature to the polymers with different degree of hydrolysis according to the reservoir and field conditions of western area in Gudao oilfield of Shengli petroliferous province. The research shows that the polymers of different degree of hydrolysis all tended to reach a same balanced value of hydrolysis through long?term hydrolysis at given formation condition. The polymer compounded with low initial degree of hydrolysis and its combination system have good long?term thermal stability at the range of 10%～40% of degree of hydrolysis.
