摘　　要：低渗透油藏具有岩性致密、物性差、孔喉细小、隔夹层发育、非均质性强、天然裂缝发育等特点,严重影响了油田开发水平的提高。本文以D1油藏为研究目标,提出油藏分层注水调整策略,同时将研究成果应用到生产中,重新修正研究参数和成果,从而形成从理论到实践再到理论的一套适合低渗透油藏开发的分层注水技术模式,为分层注水技术政策的改进及在同类油藏的进一步推广提供技术支持。Low permeability reservoirs with dense lithology,poor physical property,small pore throat,interlayer insulation development,strong heterogeneity,natural fracture development and other characteristics,seriously affect the improvement of the oilfield development.D1 Chang 6reservoir as the research target in this paper,the proposed reservoir layered water injection adjustment strategy,applying research results into production at the same time,the parameters and the revision to research results, thus forming from theory to practice and theory of a set of suitable for low permeability reservoir development mode of layered water injection technology, layered water injection technology policy improvement and provide technical support in the further promotion of similar reservoir.
