| Abstract: | Sulfonated styrene- maleic anhydride polymer （SSMA） was synthesized using： styrene and maleic anhydride as main raw material and toluene and acetone as solvents. The average molecular weight of SSMA was 2500 -4000. The evaluation results show that SSMA has good properties in viscosity reduction and heat resistance. The apparent viscosity of 4% fresh water clay mud decreases from 7.5 mPa·s to 3 mPa·s by adding 30 g SSMA/L. The apparent viscosity of CX drilling fluid with high density and undersaturation drilling fluid used in Talimu Oilfield decreases from 108 mPa·s to 75 mPa＇s and the apparent viscosity of KCl -poly- sulfonated drilling fluid decreases from 63 mPa. s to less than 34 mPa. s by adding 40 g SSMA/L. The rheological property of CX drilling fluid containing SSMA is unchanged after ageing 24 hours at 150 ℃. SSMA can be used as viscosity reducer for high - temperature and deep - well drilling fluid and has good application prospeer. |
