A Study on Seepage Flow Characteristic Parameters of Micro-gel

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.
