摘要
通过长岩心模拟流动试验、短岩心地下候凝与渗流实验,探索了低浓度微凝胶体系在多孔介质中的动态成胶特征和流动特性,测定了微凝胶的渗流特性参数,分析了微凝胶阻力系数和残余阻力系数的主要影响因素及其变化规律,对微凝胶驱数值模拟、方案设计和工艺改造有一定参考价值和指导作用。
Through long core analogue flow experiment, short core in - situ curing and seepage flow experiments, this paper studies the dynamic gelling and flow characteristics of micro - gel system with low concentration in porous medium, determines the seepage flow characteristic parameters of micro- gel, and analyzes the main influential factors and variation patterns of drag coefficient and residual drag coefficient of micro - gel. It can guide numerical simulation, planning and technological transformation of micro - gel flooding.
