Abstract: The sulfonatedystyrene(SPS ) has been prepared by sulfonation reaction of the polystyrene, which is used as a Fltrate reducer for oil well cement slurry. In addition, we have studied the influence of reaction condition on sulfonate value, the rela-tionship between the amount of API filtrate and sulfonate value
and the influence of the SPS on cement slurry's propeRies. Resuits have shown that the amount of API filtrate becomes less with the higher sulfonate value of SPS under the same condilions; the prepared SPS has good control over API filtrate; the cement slurry added the SPS becomes well tlowable and more
thermostable; the· thickening time can be adjusted to 337 minunder 12090 by the regular retarder. The SPS has been proved to have no side effects on cement slurry's other properties.

Key words: sulfonation, sulfonated polystyrene, filtrate reducer, cement slurry
