聚合物驱油是目前三次采油技术中日趋完善的提高采收率技术之一。到2014年底,经过1年多的注聚开发,孤东油田八区3-6聚合物驱开发已见到较好的增油降水效果。本文着重对前期注采动态变化特点和存在的问题进行了分析研究,根据剩余油分布情况提出并实施了较大规模的注采井网调整,取得了很好的增油降水效果,对今后聚合物驱注采井网调整的实践具有较好的指导意义和借鉴作用。
Polymer flooding is one of the most advanced technologies to enhance oil recovery in the current tertiary recovery technologies. By the end of 2014, after more than one year of injection and development, the 3-6 polymer flooding development in the eight districts of Gudong Oilfield has seen better oil and precipitation reduction effects. This paper focuses on the dynamic characteristics of the early injection and mining and the existing problems were analyzed and studied, according to the distribution of remaining oil proposed and implemented a large-scale injection well pattern adjustment, and achieved good oil precipitation effect, the future polymerization The practice of material flooding and injection well adjustment has good guiding significance and reference function.
