摘要(Abstract)：

通过线性填砂模型和透明微观模型实验,研究了弱凝胶在多孔介质中的运移规律和提高采收率的一般特性。线性填砂模型研究发现,弱凝胶在多孔介质中有较强流动性能和传播性能;透明微观模型实验研究发现,弱凝胶优先进入低阻力的大孔道,可拉伸变形通过窄小孔道,弱凝胶运移过程受到剪切稀释。弱凝胶的主要作用是驱替,而调剖只是初期或暂时的效果。
Through linear sandpack model and transparent micromodel experiment,this paper studies migration rules of weak gel in porous media and general characteristics of EOR.Study of linear sandpack model shows that weak gel has strong flow capacity and propagating performance.Transparent micromodel experiment shows that weak gel first enter wide channel with low resistance,and can extend and deform to pass narrow channel.Weak gel is diluted by shear action.The main function of weak gel is displacement,while profile modification is temporary effect.
