| 摘 要： | 通过对鄂尔多斯盆地姬塬地区延长组长9油层组物源、沉积相及其微相特征综合分析,对储层岩石学、孔隙类型、结构、物性特征研究,认为长9油层组总体属辫状河三角洲沉积体系,长91局部出现浅湖沉积,储层类型以Ⅱa、Ⅱb型为主.长91为主力油层,主要分布于三角洲前缘相带,其中盐池地区物性最优,发育良好的储集空间,为有利勘探区.

| Abstract: | According to the comprehensive analysis of provenance,sedimentary facies and microfacies of Chang-9 oil-bearing beds in Jiyuan area of Ordos Basin,and the study of the petrography,pore type,pore structure and physical properties of the reservoir,it is held that the Chang-9 oil-bearing beds generally are the braid fluvial delta sedmentary systems and locally shallow lacustrine facies.The reservoir types are dominantly Ⅱa and Ⅱb in studied area.Comprehensive study indicates that Chang-91 member is the major reservoir,and it mainly distributes in delta front belt,the reservoir property in Yanchi area is the best,the area is favorable exploration area. |
