Abstract: A new water-soluble polymer P(AM/AMPS) has been synthesized by the binary copolymerization of AM(acrylamide ) and AMPS (acrylamido-2-methyl propane sulfonic acid), in which the synthesizing conditions have been investigated. Ef-
fects of monomer concentration, temperature, initiator and polymerization time on the intrinsic viscosity number were discussed and a new fracturing fluid formulation was obtained. According to the standard SY5107-86, we evaluate the performance of the fracturing fluid in the lab, results show that the polymer fracturing fluid has good performance on resistance to heat, salt and shearing.

Key words: solution polymerization, polymer fracturing fluid, additives
