Cross-linked polyacrylamide, which increases in volume many times in contact with water.
APPLICATION:
During drilling and overhaul of wells, eliminating areas of absorption of process solutions, conducting remedial cementing. The water-absorbing composition is based on the ability to absorb water or water solutions and retain them in its structure, even when exposed to certain pressures, while increasing the volume of polymer particles, due to which the latter are retained in the pore volume, blocking them.
CHEMICAL EFFECT:
