| 摘 要： | 升平油田具有典型的陆相多油层储层特征,其开发目的层为葡萄花油层的葡一组,地层平均厚度约50 m,分为11个含油小层.储油层具有砂体薄、连通性差、开发效果较差等特点,可能存在有剩余油.为进一步确定剩余油的分布规律,提高原油采收率,开展了储层流动单元的研究工作.岩性、测井等资料的综合分析确定,本区主要发育有三角洲前缘亚相的水下分流河道、主体席状砂、非主体席状砂和河道间4种沉积微相.在此基础上应用聚类分析方法建立了本区的储层流动单元划分标准,并在本区划分出A、B、C、D、E 5类储层流动单元,其中A类是最好的储层流动单元,B类是次好的储层流动单元,E类是无效储层.沉积微相和流动单元空间分布的对比说明,前者好于后者,且有利于发现剩余油.

| Abstract: | Shengping oil field has multiple oil-layers with typical continental reservoir features. Its development objective layer is the first member of Putaohua reservoirs. The average thickness of the layer is about 50 meters, including 11 oil-bearing sublayers. The sandstone of the reservoir is thin, connectivity is bad, development effect is poor, residual oil may exist. To further confirm the distribution of residual oil and to enhance oil recover ratio, research of reservoir flow units has been carried out. Based on comprehensive analysis of lithology and well-logging data, it is concluded that there are four sedimentary microfacies, including underwater distributary channel, main sand sheet, minor sand sheet and interchannel of delta-front.Division standard of reservoir flow units of the research area is set up and five types reservoir flow units are classified according to cluster analysis. Type A is the best, B is better and E is useless. Contrasting the spatial distribution of reservoir flow units and sedimentary microfacies shows that the former is finer than the latter and is very advantaged to find residual oil. |
