摘　　要：目的对有效提高产能和注水开发效果的措施进行分析,提出合理化建议。方法通过沉积微相、储层综合定量分析、产层生产动态资料进行综合评价。结果本次划分,选取了有效厚度、孔隙度、渗透率、突进系数、流动带指数等参数,以元城油田元54区长1油层组为例,将储层划分为E、G、M、P 4类流动单元。结论各类流动单元与储层沉积微相、岩性、物性和油层初始产能具有很好的对应关系,能够真实客观地反映特低渗砂岩储层物性差、非均质性强的地质特点。Aim To analyze and propose the rational measures of enhancing the production and flooding development effect effectively in all kinds of flow units.Methods Based on comprehensive quantitative analysis and evaluation of sedimentary microfacies and reservoir.Results Taking Yuan 54 Areas Chang 1 formation in Yuancheng oil field as an example,five parameters,including efficiency thickness,porosity,permeability,dash factor and flow-zone index are selected for.The formation is finely divided into 4 types of flow units,including E,G,M,P.Conclusion The results can be verified with production behavior data each other and show that the selected values of parameters,comprehensive evaluation functions and indexes for the flow unit division can truly and objectively reflect the geologic features of ultra-low permeability reservoir,such as poor property characteristics and strong heterogeneity.
