摘要(Abstract)：

基于江苏油田窄条状油藏孔隙分布规律、主控因素分析和不同类型岩心的驱替实验,应用水驱、聚合物驱、表活剂驱、聚表二元驱及弱凝胶驱等方式研究了剩余油动用规律。结果表明:窄条状油藏不同部位储层的孔隙变化特征不同,靠近边水部位的较大孔隙的变化较大,腰部位次之,高部位最小;水驱倍数、孔喉大小、黏土矿物含量等是影响孔隙分布的主要因素;靠近边部的岩心适合弱凝胶驱,腰部位适合聚表二元驱,顶部在高速水驱或聚合物驱时效果较好。研究结果为剩余油挖潜提供了理论依据。
Based on the distribution rules of the pores,main controlling factors' analyses and flooding experiments of different types of the cores in the narrow-stripe reservoirs in Jiangsu Oilfield,the developed rules of the remained oil are studied by means of the methods such as water flooding,polymer flooding,surfactant flooding,polymer-surfactant flooding,weak gel flooding and so on.The results show that the changed characteristics of the pores in the different parts of the reservoirs are different:the changes of the pretty larger pores nearby the edge water are more greater,the next is the waist,the least is the top;the main influencing factors for the pore distribution are PVs,pore sizes,clay mineral content and so forth;the cores nearby the margins are suitable to be flooded by the weak gel,the waist is adaptable to be displaced by the binary flooding,much better results are obtained on the top by means of high-speed water flooding or polymer flooding.The research achievements have provided a certain theoretieal evidences for the tapping of the remained oil.
