| 摘 要： | 以取心井岩心分析资料为基础,结合测井相分析,对八面河油田北区、广北区沙三段的沉积微相特征及沉积模式进行详细研究.研究表明,沙三段以曲流河三角洲沉积为主,沉积物粒度细,以细砂岩、粉砂岩为主,垂向层序总体表现为向上变粗的反旋回层序.沙三段主要发育三角洲前缘亚相,包括水下分流河道、河口坝、远砂坝、席状砂、支流间湾等微相类型.

| Abstract: | Based on core analysis data in coring wells, sedimentary microfacies characteristics and sedimentary modes in Es3 of North Region and Guangbei Region of Bamianhe Oilfield are studied in detail in combination with well logging faci-es analysis. The study shows that Ess is mainly consisted of meandering deltaic sediments of fine particles, which mainly includes fine sandstones, siltstones, vertical sequency presents unnormally-graded. The main growth in Es3 is deltaic frontal parfacies, which includes microfacies of subsea distributary channel, mouth bar , distal bar, sheet sand, bar between branches. |
