【摘要】 本论文在对研究区地质背景和开发现状充分认识的基础上，采用静动态结合的分析方法，对濮城油田南区沙二上2+3油藏的储层特征与剩余油分布进行了研究。通过岩心观察和描述，结合大量的测井和录井资料，认为研究区主要为物源来自鲁西隆起的末端扇沉积体系。对二百多口油水井进行了测井资料的二次数据处理，求取了各类储层参数。对各砂层组层内、层间和平面非均质的研究，认为研究区储层层内非均质性以严重非均质型为主；整个井段层间非均质性也以严重非均质性为主；整个砂层平面非均质性都比较强。油藏在平面上隔层分布比夹层相对稳定；纵向上隔层分布稳定，夹层分布零散。将研究区14个小层划分为四类流动单元，即流动单元P(存储性和渗流性差)、流动单元F(存储性和渗流性较好)、流动单元G(存储性和渗流性好)和流动单元E(存储性和渗流性很好)；总体来说以G类流动单元为主。在对油水井及井组动态分析的基础上做出主流线图以及水淹图；研究区除了个别油层中等水淹以外，大部分油层连片形成强水淹。在储层特征综合描述评价的基础上，利用数值模拟方法，确定含油饱和度和剩余油储量丰度的分布规律，提出了综合调整措施。更多还原

【Abstract】 Based on the full understanding of the study area geological background and the current development status, using the static and dynamic analysis method, we study the reservoir and renmaining oil distribution of Es2 upper 2+3 reservoir in the south area of Pucheng oilfield. According to the core’s observation and the description, coalescent a great deal of log and the logging information, we proposed that the research area is the terminal fan deposition system whose source comes from LuXi uplift. According to the secondary digital process of more than 200 oil and water wells’ log data, we obtain various reservoir parameter . By researching the heterogeneity of inner layer, interlayer and horizons , we conclude that the heterogeneity of inner layer is serious ; the heterogeneity of interlayer which is serious in 2 sand group , is level in 3 sand group , is serious in the total ; the heterogeneity of horizons is a little serious . The average restraining barrier is thicker than the interbed’s in plane ; The restraining barrier is more steady than the interbed in vertical . The study area is ploted into 4 flow units as P , F, G and . E flow unit , the memory and percolation turns better .The channel line map and watered-out map is drawn based on the dynamic synthesis of the oil and water wells and groups .All the oil layer is watered except several area . Based on the general value of reservoir , using the numerical simulation , we conclude the distribution rule of the oil saturation and the remaining oil reserves abundance, and propose the comprehensive adjustments.更多还原
