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.
目的 對有效提高產能和註水開髮效果的措施進行分析,提齣閤理化建議.方法 通過沉積微相、儲層綜閤定量分析、產層生產動態資料進行綜閤評價.結果 本次劃分,選取瞭有效厚度、孔隙度、滲透率、突進繫數、流動帶指數等參數,以元城油田元54區長1油層組為例,將儲層劃分為E、G、M、P 4類流動單元.結論 各類流動單元與儲層沉積微相、巖性、物性和油層初始產能具有很好的對應關繫,能夠真實客觀地反映特低滲砂巖儲層物性差、非均質性彊的地質特點.

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 flowzone 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.
