在矿场试验中,将聚合物驱和交联聚合物驱2种驱剂组合后进行驱油,研究其现场应用过程中的开采特征和驱替效果,以此探寻一种适于河南油田的最佳驱替方式。从室内试验及矿场应用2方面对该项技术进行了讨论,并以下二门油田H2Ⅲ油组为例阐述了该项技术的技术特点和现场应用效果。对比分析表明,聚合物驱+交联聚合物驱的驱替效果好较之单一段塞的驱替效果要好。
In the field test, polymer flooding and cross-linked polymer flooding two kinds of flooding agent combination of flooding, to study the field application process of mining characteristics and displacement effect, in order to explore a suitable for Henan oilfield The best way to replace. This technology is discussed from two aspects of indoor experiment and mine application. The technical performance and field application of this technology are illustrated with the example of H2Ⅲ oil field in Ermen Oilfield. The comparative analysis shows that the flooding effect of polymer flooding + cross-linked polymer flooding is better than that of single slug flooding.
