摘　　要：针对孤东二区油藏及地下流体特点 ,成功地研制了适于孤东二区注入的交联聚合物体系。该体系交联时间适宜、流动性好、强度较高、增粘性好。通过调整体系浓度 ,可以实现对成胶时间和成胶强度的控制。实验表明 ,该体系可同时用于调剖及驱替。文章对该体系的最低成胶浓度、成胶时间、粘度、强度、稳定性等性能进行了评价。深入研究了油砂、剪切、浓度等因素对成胶、稳定性等方面的影响 。According to the reservoir and underground fluid properties of Gudong 2 area, injected cross?linked polymer system fitting to Gudong 2 area has been developed successfully. This system has suitable cross?linking time, good flowability, high strength and good viscosified property. Gel time and gel strength may be controlled through adjusting the concentration of polymer. The experiment shows that the system may be used for profile control and displacement simultaneously. Lowest gel concentration, gel time, viscosity, strength and stability and so on are all evaluated in this paper. The influence of the factors such as oil sand, shear and concentration on gel and stability has been studied throughly, and the optimum formula is ascertained.
