主 题：Nanoparticles-stabilized polymer gel Water shut-off Gelation time Crosslinkers Accelerator Gel stability
摘 要：Excess water production is one of the crucial complications in the oil industry,leading to a rapid decline in oil *** overcome this problem,different polymer gels are used to block the water s path to reduce water *** the present work,polymer gel systems were prepared with polymers namely partially hydrolyzed polyacrylamide(PHPA),organic crosslinkers like hexamine,and hydroquinone with the incorporation of silica and alumina *** are used to enhance the stability of the gel framework in high salinity and high temperature reservoir *** designing the polymer gel system,factors such as pH,thermal stability,brine composition,injection rate,and chemical concentration were *** of PHPA and nanoparticles were varied from 1 to 2 wt% and 0.25e1.0 wt% respectively for the preparation of different gel *** concentration of the organic crosslinker was extended from 5000 to 11000 ppm for investigating the effect on gelation *** concentration was chosen from 2 to 8 wt% to find the impact of high *** acid as an accelerator was also used to study the effect on gelation time,and it was found that the gelation time is reduced as the concentration of succinic acid *** prepared polymer solution was taken in a test tube and was kept inside a hot air oven at 95℃ to perceive the gelation time and nature of the produced *** showed that nanoparticles do not influence the gelation time,but they considerably affect gel ***,concentrations of polymer,accelerator,and salt(salinity)have significant effects on the gelation behavior of the gel systems.
