目前常用聚合物驱是部分水解聚丙烯酰胺,该物质面对油藏条件的复杂性和多样性时,不能有效建立残余阻力系数,因此迫切的需要找到一种能适应侏罗系油藏油层丰度低、岩性致密、储层物性差,层内非均质性强的低渗透岩性油藏的调剖剂.%The current commonly used polymer flooding is partially hydrolyzed polyacrylamide,in the face of the reservoir conditions of complexity and diversity,can not effectively establish the residual resistance coefficient,so urgent need to find a can adapt to the low abundance of Jurassic reservoir and tight lithology,reservoir physical property is poor,intraformational heterogeneity of low permeable lithologic reservoir profile control agent.
