Abstract: Using Acryie Amide and Acrylic Sulfonate ropolymer(AM/AS),Hvdroxv Ethvlol Cellulose( HEC)and lxrlyethene ozidalion(PEO) as filtrate reducer in non-solvent to Than gr the form of marronrolerule,we have studied the relationship hetvrrn fluid loss and the changing form of marrornolrcule。and learned the mechanism of thr filtratereducers. Results shous that when the
amount of non-solvent is more Thanthe amount in solvent,the adsorbing, curling and precipitating of macrolecule on the surface of cement particles contribute to plugging the passage of fluid loss and reducing the permeability of the filter cake, so that the amount of fluid loss of cement slurry is greatly reduced.

Key words: cement slurry, filtrate reducerr, polymer, θ solvent
