  • A filter loss reducer for use in oil well cement slurries was synthesized with(AMPS), N, N-Dimethylacrylamide(DMAA), 3-Allyloxy-2-hydroxy-1-propanesulfonic acid(AHPS) and acryl acid(AA).Molecular structure and thermal stability of the copolymer were characterized using IR and TG.Laboratory evaluation of the copolymer showed that API filter loss of a cement slurry(3%-6%) can be reduced to less than 50 mL.The copolymer functioned well at 180℃ or under contamination of the cement slurry by 36% of salt.Laboratory evaluation shows that the filter loss reducer control filter loss by changing electrical porperties of filter cake and increasing viscosity of cement slurry.Thickening time of the cement slurry was also slightly prolonged.
