Selective Water Control of a Relative Permeability Modifier

Abstract

Abstract:

The static adsorption and selective water shutoff performance of a cationic polymer type relative permeability modifier（
RPM）were studied. The results show that the static adsorptions of RPM on quartz sands and oil sands are both langmuir
adsorption，and the adsorption on quartz sands is twice of that on oil sands；the static adsorption is strongly affected by electrostatic
attraction and the wettability of solid surface，and RPM can alter the oil wet surface（105°）to weakly water wet（72°）；
core flood tests are conducted to study the selective water shutoff of RPM，and it shows that the oil and water residual resistance
factors decreases with the increase of permeability，temperature and brine salinity. The swelling/shrinking of polymer
adsorption layer is a reasonable explanation for RPM selective water control.

Key words: cationic polymer, relative permeability modifier, static adsorption, wettability, selective water control
