| 摘 要： | 为进一步提高大庆油田原油采收率,利用热采物理模拟技术,开展聚合物驱后油藏蒸汽驱提高采收率实验研究,探讨聚合物驱后转蒸汽驱的可行性。实验结果表明,油藏聚合物驱后转蒸汽驱不仅能够改善高、中渗层的驱油效率,且蒸汽的超覆作用能够有效动用油层上部剩余油,提高波及效率。聚合物驱后油藏转热采方式在技术上是可行的。该研究为大庆聚合物驱后油藏蒸汽驱现场试验提供了依据。

| Abstract: | In order to further enhance oil recovery in Daqing Oilfield,the technical feasibility of steam flooding after polymer flooding has been studied through physical simulation.The experimental results indicate that steam flooding after polymer flooding can improve oil displacement efficiency in high and medium permeability zones,meanwhile steam overlap effect can effectively drive remaining oil in the upper part of the oil reservoir and improve sweep efficiency.Thermal recovery after polymer flooding has been p... |
