安第斯油田属于典型的高温高盐碎屑岩油藏，在高温（95℃）、高盐（71.5 g/L）的条件下，为了提高聚合物耐温耐盐性能，并且考虑到该油田裂缝发育，油层非均质性严重，采用 APP5/乌洛托品凝胶体系进行实验。通过室内实验对凝胶体系的耐温性、抗盐性、稳定性和封堵能力进行评价，并通过驱油实验，对比单一聚合物与凝胶体系的驱油效果。得出以下结论：凝胶体系具有更好的耐温耐盐能力，封堵效果较好，凝胶体系驱油比单一聚合物驱油采收率高。

ANDES oilfield belongs to typical high temperature and high salinity clastic rock reservoir. Under the conditions of high temperature (95 ℃) and high salinity (71.5 g/L), in order to improve the ability of anti-high temperature and high salinity of polymer, and taking into account of the fracture development and heterogeneity in oilfield, the APP5/ urotropin gel system was used in experiments. Through the indoor experiment, the abilities of temperature resistance, salt resistance, stability and sealing of gel system were evaluated. And flooding effects of single polymer and gel system were compared by oil displacement experiment. The results show that, the gel system has better ability of resistance to temperature and salt and salt resistance, plugging performance, and the gel system has higher oil recovery than single polymer.
