摘    要:在沉积微相、储层物性特征分析的基础上,选取孔隙度、渗透率、流动带指数等参数,对泌阳凹陷赵凹油田泌301 井区核三段油层组进行流动单元划分。依据流动带指数的大小,将研究区目的层段划分为A、B、C、D 和E 等5 类流动单元。通过研究发现,各类流动单元与物性、岩性、沉积微相之间具有较好的对应关系,同时对不同流动单元产能进行了分析。研究结果表明,流动单元的划分能够真实客观地反映储层物性差、非均质性强的地质特点,单井产能与流动带指数有较好的乘幂关系,不同流动单元产能差异较为明显,物性最好的A 类流动单元产能最高,物性最差的E类流动单元产能最低。

关 键 词:流动单元   流动带指数   产能分析   泌301 井区   泌阳凹陷

Abstract:On the basis of the sedimentary microfacies and the analysis of reservoir physical properties,a series of parameterssuch as the porosity,permeability,flow zone index,etc,were selected for the classification of the flow units of oil formationof Bi-301 wellblock H3 Member in the Zhaowa Oilfield of Biyang Depression were classified. According to the value of flowzone index,the studying area has been divided into five flow units,named FU-A,FU-B,FU-C,FU-D and FU-E. The resultshows that all kinds of flow units have good corresponding relation with physical property,lithology,sedimentary microfacies.Besides,the productivity of different flow units is analyzed. The results mainly indicate three respects. First,flow units’ classificationobjectively reflects the geological characteristics of poor reservoir property and strong heterogeneity. Second,thereexists very significant power correlation between the single well productivity and flow zone index. Finally,the productivitydifferences of different flow units are obvious,and FU-A with the best physical properties has the highest productivity while Eflow unit with the worst physical properties has the minimum productivity.
Keywords:flow units   flow zone index   productivity analysis   Bi-301 Wellblock   Biyang Depression
