泌阳凹陷双河油田Ⅱ５层是复杂的厚油层，非均质性严重，剩余油分布复杂，且油藏温度高达７３℃。１９９１年开展该油层高温聚合物驱油技术研究，经多种聚合物性能评价，找到了热氧影响聚合物性能的界限，优选出耐高温聚合物，改进和优化了地面注入工艺，制定了经济有效的聚合物驱方案。现场实施阶段增油４．３５×１０４ｔ，提高采收率９．０３％，效果显著。形成了高温聚合物驱的室内试验、油藏工程研究、聚合物性能评价、地面注入设备优化和经济效果评价的一套方法及配套技术，为在双河油田推广应用高温聚合物驱油技术奠定了基础。图２（郭海莉摘）
The Ⅱ5 layer of Shuanghe Oilfield in Biyang Depression is a complex thick oil layer with serious heterogeneity and complicated distribution of remaining oil. The reservoir temperature is as high as 73 ℃. In 1991, the research on this polymer flooding technology was carried out. Based on the evaluation of various polymer properties, it was found that the influence of thermal oxygen on the properties of polymer was better. High temperature resistant polymer was selected, ground injection process was improved and optimized, Effective polymer flooding scheme. Field implementation phase 4.35 × 104t increase oil, oil recovery increased 9.03%, the effect is significant. A set of methods and supporting technologies for indoor experiments, reservoir engineering, evaluation of polymer properties, optimization of ground injection equipment and evaluation of economic effects of high temperature polymer flooding have been formed, laying a solid foundation for the popularization and application of high temperature polymer flooding technology in Shuanghe Oilfield The foundation.
