Abstract

Fluid loss additive is the main component of the cementing fluid. This article use monomer the monomers of 2-acrylamido-2-methyl-propanesulphonic acid (AMPS) and N, N-dimethyl acrylamide (DMAA) by the method of aqueous solution polymerization to synthesis the novel fluid loss additive ANMG1305. Discuss the amount of initiator, the molar ratio of monomer, reaction temperature, which the influence on the properties of the polymer. Through the infrared spectrum, thermo-gravimetric analyzer, viscometer, such as instrument on its microstructure and properties were characterized. We know that all the monomers are involved in the reaction and the polymer has an excellent thermal stability though the microstructural characterization and application performance of the novel fluid loss additive.
