Abstract: This paper studied the chemical composition of the cement filtrate in the slurry with or without additive,tested the compatibility of mud-cement and formation brine-cement.Based on the analysis of cement filtrates with different additives,a new way to reduce the damaging ion concentration in cement filtrates is to use the additive which has no poisoning to the nucleation process of calcium hydroxide,which can loweer formation damage caused by cement filtrates.

Key words: filtrates, oil reservoir, cement additive, induction period
