| 摘 要： | 利用高分辨率层序地层学理论和技术方法、综合测井、地震和岩芯资料对鄂尔多斯盆地白豹地区长6油层组地层进行高分辨率层序地层学分析,从中识别出超短期、短期、中期、长期4个级别的基准面旋回层序,依据等时地层对比法则并利用地震资料约束进行不同级次基准面旋回层序的联井对比,建立了长6油层组等时地层格架,在等时地层格架内讨论沉积充填演化序列和储、隔层发育特征。

| Abstract: | On the basis of integrated logging,seismic data,and core,the sublacustrine fan sedimentary system of the Chang 6 Oil Reservoir in the Baibao area,Ordos Basin is divided into ultrashort-term,short-term,mid-term,and long-term base-level cycles.The base-level cycles of different orders are correlated based on seismic interpretations and cycle isochrostratigraphy.Isochronous stratigraphic frameworks are established.Finally,patterns of sediment accumulation and characteristics of reservoir and barriers are analyzed under the newly established isochronous stratigraphic frameworks. |
