孤岛油田中一区馆３油层注聚合物试验区为高渗透、高饱和度、高粘度、非均质严重的正韵律亲水疏松砂岩油藏，注水开发已有２１年历史。到１９９２年，综合含水达９０．８％。本文介绍了应用三次采油数模技术，针对油藏特点进行水驱历史拟合、污水配制聚合物溶液和注入方式优选及效果预测的方法和结论，为该区聚合物驱现场实施方案的确定提供了科学依据。矿场试验两年的变化情况与数模预测的结果吻合较好。

Gudao 3 Reservoir in Central District 1, Gudao Oilfield, is a positive rhythm hydrophilic loose sandstone reservoir with high permeability, high saturation, high viscosity and serious heterogeneity. Water injection has been developed for 21 years. By 1992, the combined water content amounted to 90.8%. This paper introduces the methods and conclusions of applying the tertiary recovery oil-and-mold technology, history of waterflooding according to the characteristics of reservoirs, selection of polymer solution and injection method for wastewater preparation and prediction of effect, and provides the methods for determining the implementation plan of polymer flooding field in this area The scientific basis. The changes of two years of mine test coincided well with the results of numerical simulation.
