聚合物驱分层注入研究

Research on separate zone polymer flooding.

进一步提高聚合物驱油效果 ,其中最有效的手段之一就是改善注聚层间吸水状况 ,有效地扩大波及体积。针对胜利油区油藏和水驱开发特点 ,以室内实验、数值模拟及油藏工程研究为基础 ,对分层注聚采油进行了研究。研究结果表明 ,分层注入可以有效地控制层间聚合物溶液的注入量 ,效果好于合注。在矿场应用中 。

For further enhancing polymer flooding effect, improving intake capacity between the layers and expanding swept volume effectively is one of the most effective means. To counter the development features of reservoir and waterflooding in Shengli oilfield, the separate zone polymer flooding is studied based on the lab experiment, numerical simulation and reservoir engineering research. The study results show that separate zone polymer flooding can effectively control interlayer injected polymer solution, its effect is better than that of commingled injection. The significant result is also obtained in field application.
