孤东油田聚合物驱工业化应用的主要做法及效果

Application and experience of commercial polymer flooding in Gu-dong Oilfield

在1994年开展的工业性聚合物驱试验取得成功经验的基础上,孤东油田于1997年投入聚合物驱工业化应用,对聚合物驱油理论和实践进行了探索,提出了“一井一制”等聚合物注入新方法,对注入工艺等进行了配套优化,形成了新的思路和成熟的聚合物驱配套技术。随着聚合物驱规模的逐年扩大,年增油量和累积增油量逐年增加,到2005年底累积增油量为234.7×108t,为孤东油田的持续稳产提供了重要的技术支撑。

Based on the success of commercial polymer flooding experiment in 1994, commercial application of polymer flooding is begun in Gudao Oilfield in 1997. Oil displacement theory and practice of the polymer flooding are explored. Some new polymer injection methods are put forward such as ' one well one system' method. The injection technologies are optimized. New thought and mature complete polymer techniques are formed finally. Yearly and cumulative incremental oil production are more year by year along with the enlarging polymer flooding scale year by year. The cumulative incremental oil production is 234.7 × 108t by the end of 2005. It provides important technical support for continue stable production in Gudong Oilfield.
