ABSTRACT = {CO2 or acidic material injection into oil reservoirs or Alkaline-surfactantpolymer (ASP) flooding induces reactivity between CO2, acid, ASP, pore-waters
and minerals, which results in modification of porosities and permeabilities. We
use dilation operation to simulate the modification of the porosities and study the
variation of permeabilities. Firstly we get digital images from CT experiment of
a real rock core. Secondly the pore space of digital cores is expanded by dilation
operation which is one of basic mathematical morphologies. Thirdly, the distribution of pore bodies and pore throats are obtained from the pore network modeling
extracted by maximal ball method. Finally, the relation between network modeling
parameters and permeabilities is analyzed.<br/>
The result is that the throat change influences the permeability exponentially and
that permeabilities are significantly influenced by the big throats.},
