摘　　要：大庆油田小井距南井组萨Ⅱ７＋８层特高含水期注聚合物试验，中区西部单层和双层聚合物驱油试验，以及北一区断西、喇嘛甸南块的工业性聚合物试验，都取得了较好的开发效果，聚合物的注入工艺日趋完善，到１９９５年末，可用上油田自产的聚和物和低矿化度水源。Recently, a series of experiments, including the polymer-injection in the Sa-Ⅱ-[7+8] beds, which is in extremely high water-cut stage, in south well group, closely well spacing area inlhe Daqing oilfield, the polymer flooding in single and double layers in western middle block, as wen as the polymer flooding experiments on a layers in western middle block, as well as the polymer flooding experiments on a large scale in western north-1block (Dualal area), southern Lamadian block, are all successful. Productions in the areas mentioned above arebeing improved gradually with the perfecting of the polymer-injection technique. The author believed that the polymer material and low salinity water produced by the Daqing petroleum administration itself might be utilized by the end of the 1995.
