摘　　要：多级分层酸化管柱就是针对多层系开发油藏而应用的剖面改善工艺。它通过多级封隔器和滑套开关,将多个层系分隔开来,根据不同层系油层的污染原因和污染程度分别挤入针对性的酸液体系和用量,从而有效改善吸水剖面,增加有效注水。multi-layer zonal acidulation pipe strings are for profile improvement during production of multi-layer reservoirs, which separate these layers with multi-level packers and sliding sleeve switches and can determine pertinent acidulation fluid systems at proper dosage on the basis of damage causes and damage degrees of different layers, thus greatly improving the water injection profile and making water injection more effective.

关 键 词：多级分层酸化管柱 吸水剖面 酸化解堵 渗透率 非均质性油藏 酸化技术 应用 级分 多层系 分层酸化
