【摘要】:通过取芯、分析化验、扫描电镜等资料分析,对尼日尔三角洲的岩石学特征、沉积特征及储层的主控因素进行了研究。结果表明:研究区储层以石英砂岩为主,长石质石英砂岩和岩屑质石英砂岩次之;主要发育水道和朵叶体系,其中水道体系可细分为主水道、砂质天然堤、泥质天然堤、底部滞留沉积;朵叶体系细分为朵叶主体、朵叶侧缘,两者共同由14种岩相类型组成。建立了西非重力流沉积微相的岩相组合模版,提出了重力流复合水道和复合朵叶的沉积模式;明确了储层演化的影响因素。
[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.
