摘　　要：通过借鉴以往注聚区块的经验,结合喇嘛甸油田北西块的地质特征和注入过程中的动态变化,采取了井网优化、注入超高相对分子质量聚合物溶液、注聚前整体调剖等整体方案的优化以及注聚过程中采用注入井调分结合、采油井压堵并重等配套调整措施,使该区块取得了显著的开发效果,提高了聚驱整体经济效益。Based on experience of polymer injection in some blocks, the geologic features of northwest block in Lamadian oilfield, and the dynamic changes during polymer injection, some measures have been taken to improve the development results in this block. The methods include, optimization of overall program, such as optimization of well pattern, injection of polymer solution with relatively ultra high molecular weight, overall profile control before polymer flooding, etc., and some matched modification methods, such as the combination of profile control and separate layer injection in injector wells and well kill and water shut-off in production wells. Finally, the total economic benefits of polymer flooding are improved.
