| 摘 要： | 应用鄂尔多斯盆地延长组6-2油藏的沉积相标志，研究了镇泾区块岩相标志、测井相标志，确定了该区的沉积类型主要为三角洲沉积体系的三角洲前缘沉积，识别出了水下分流河道、水下天然堤、水下决口扇、河口坝和水下分流间湾5种微相类型，分析了各种沉积微相的电性特征，并且揭示了各种沉积微相在平面上的展布和剖面上的分布，进而总结出了沉积演化规律。由于水下分流河道的侵蚀强烈，河口坝发育相对较少。有利的砂体储集体主要是水下分流河道，它主要发育在长6^2-2油层。

| Abstract: | By systematical analysis of the marks of sedimentary facies of Reservoir Chang 6-2 of Yanchang Formation in Ordos Basin, the main sedimentary types were identified in this area which were the delta front depositions of the delta depositional system. It has five microfacies developed, including underwater distributary channel, underwater natural levee, sub-aqueous crevasse splay, mouth bar and underwater distributary interchannel. Eteetric features of sedimentary microfacies characteristics were determined. ... |
