摘　　要：为了提高油田聚驱整体开发效果 ,最大程度地提高原油采收率 ,在以往聚驱层系组合原则研究成果的基础上 ,通过聚驱开发实践总结和数值模拟技术 ,对开发层系组合的基本单元、一套开发层系内层间渗透率级差界限、油层沉积条件和油砂体沉积类型、隔层条件以及一套开发层系的组合厚度等多种聚驱层系组合所需考虑的因素进行了详细的研究 ,并综合考虑聚合物利用率、油田聚驱整体开发效果以及喇萨杏油田实际油层条件 ,制定出一套合理的层系组合原则 ,为大庆油田聚驱开发的层系组合问题提供了理论基础。利用此套原则划分开发层系 ,可以更有效地细分层系 ,最大程度地满足不同油层渗透率和分子量的匹配关系 ,从而避免了资源的浪费 ,提高了聚合物利用率。In order to improve overall oilfield developing results and enhance recovery rate, various factors that need to be considered in combining series of strata in polymer flooding are studied in detail, i e. basic unit of developing series of strata combination, differential permeability limit in one set of developing series of strata, formation depositional conditions and depositional type of oil sand, barrier layer conditions, and combination thickness. These studies are based on former achievements in combining series of strata, polymer flooding practice and numerical simulation. Polymer utilization ratio, overall polymer flooding results and actual formation conditions of Lamadian Saertu Xingshugang oilfields are considered. Based on all these factors, a set of rational combining principles is put forward, so the theoretical base for series of strata combination in polymer flooding in Daqing oilfield is provided. By applying this set of principles, series of strata can be subdivided more effectively, match between permeabilities with molecular weight in different formations can be satisfied in maximum degree, thus resource waste is avoided and polymer utilization ratio is improved.
