Performance evaluation of optimized preformed particle gel (PPG) in porous media
چکیده انگلیسی
PPG injection pressure increases with cross linker concentration, PPGs particle size, and brine concentration and injection flow rates but decreases with the increase of permeability and temperature during PPG injection. It was shown that increased injection rate does not increase PPG injection pressure to the same level and the reduction in water permeability caused by swollen PPG prepared in high salinity brine is higher than that prepared in low salinity brine. Synthesized PPGs can also change the permeability of different slim tubs to the same level. Resistance factor (RF) and residual resistance factor (RRF) increase with the increase in PPGs particle size, brine salinity and cross linker concentration. But, they decrease with the increase of temperature and the flow rate. Initially RRF increased gradually as the permeability of slim tubes decreased from 395 to 137 Darcy but a sharp increase in RFF caused by swollen PPG in low permeability slim tube was observed.
