| 摘 要： | 通过对岩心的观察、测井曲线的划分,结合野外剖面及其他地质资料,对鄂尔多斯盆地旦八地区长4＋5油层组21口井的单井微相进行了划分。研究认为：旦八地区长4＋5主要为陆相河湖三角洲沉积体系,进而可以细分为三角洲平原与三角洲前缘亚相,为下一步有利区的预测奠定了基础。 |

| Abstract: | Through the observation to the cores and the classification of logging curves,and connecting with the field profiles and other geophysical data,this paper makes single-well micro-facies classification of 21 wells of Chang4+5 pay set of Triassic Yanchang Formation in Zhidan-Danba Area of Ordos Basin.The study holds that the Daba Area of Chang4+ 5 pay set is mainly the delta sedimentary system which could be subdivided into two sedimentary subfacies,delta plain facies and delta front intrafacies,laying a foun... |
