【摘要】：通過取芯、分析化驗、掃描電鏡等資料分析,對尼日爾三角洲的巖石學(xué)特征、沉積特征及儲層的主控因素進(jìn)行了研究。結(jié)果表明:研究區(qū)儲層以石英砂巖為主,長石質(zhì)石英砂巖和巖屑質(zhì)石英砂巖次之;主要發(fā)育水道和朵葉體系,其中水道體系可細(xì)分為主水道、砂質(zhì)天然堤、泥質(zhì)天然堤、底部滯留沉積;朵葉體系細(xì)分為朵葉主體、朵葉側(cè)緣,兩者共同由14種巖相類型組成。建立了西非重力流沉積微相的巖相組合模版,提出了重力流復(fù)合水道和復(fù)合朵葉的沉積模式;明確了儲層演化的影響因素。
[Abstract]:The petrological characteristics, sedimentary characteristics and main controlling factors of reservoir in Niger Delta are studied by means of coring, analysis and analysis, scanning electron microscope and other data. The results show that quartz sandstone is the main reservoir in the study area. Feldspathic quartz sandstone and lithic quartz sandstone followed; The main waterways and leaf-bearing systems are developed, in which the watercourse system can be subdivided into main waterways, sandy natural levees, muddy natural dikes, and the bottom remaining deposits; The flower leaf system is subdivided into the main flower leaf and the lateral edge of the flower leaf, which are composed of 14 lithofacies types. The lithofacies combination template of the gravity flow sedimentary microfacies in West Africa is established. The sedimentary model of gravity flow composite channel and compound flower leaf is proposed. The influencing factors of reservoir evolution are defined.
