高温交联聚合物驱是聚合物驱技术的完善和发展,解决了普通聚合物驱适应温度小于85℃、矿化度小于10000mg/L的技术局限。室内试验证明了交联聚合物成胶性能好、在地层中建立流动阻力大、适合于高温高矿化度油藏,现场单井试注总结了交联聚合物驱技术特征并进行了配方改进和优化。研究表明,在双河油田江河区Ⅶ上层系高温、高矿化度、低粘油藏条件下,可以通过开展高温交联聚合物驱来进一步提高采收率。 High temperature cross-linked polymer flooding polymer flooding technology is the perfection and development, to solve the common polymer flooding adaptation temperature is less than 85 ℃, salinity less than 10000mg / L technical limitations. Laboratory tests show that the cross-linked polymer has good gelation performance, large flow resistance in the formation, suitable for high temperature and high salinity reservoir, and single-well test on-site to summarize the technical characteristics of the cross-linked polymer flooding and to improve the formulation And optimized. The research shows that under the condition of high temperature, high salinity and low viscosity oil reservoir in the upper Ⅶ of Jianghe district of Shuanghe Oilfield, the oil recovery can be further enhanced by carrying out high temperature cross-linked polymer flooding.
