针对中二北馆3-4原油粘度高,储层非均质性严重、储层大孔道普遍存在等问题,深化储层认识,提高注聚区井网完善程度;优化注聚参数,提高聚合物对油藏的适应性;强化堵调结合,不断改善注聚剖面,逐步形成了一套高段塞聚合物驱矿场注采管理技术,取得了良好的开发效果。综合含水比注聚前下降7.1%,已累积增油52.1×10~4t,提高采收率3.3%。对今后同类油藏开展高段塞聚合物驱具有一定的参考价值。 In view of the problems of high viscosity, serious reservoir heterogeneity and large pores in reservoirs in 3-4 Middle Second Middle School, deepen reservoir understanding and improve perfection of well pattern in injection zone; optimize injection polymerization parameters and increase polymerization The adaptability of the reservoir to the reservoir; strengthening the combination of blockage and regulation, continuously improving the injection profile, and gradually forming a set of injection and production management technologies for high-slug polymer flooding field, and achieved good development results. The combined water cut decreased 7.1% before injection, accumulatively increased oil 52.1 × 10 ~ 4t, and enhanced oil recovery 3.3%. It is of certain reference value to carry out high slug polymer flooding in similar reservoirs in the future.
