Abstract: The performances of sulfomethylated tannin of tara (Caesalpinia spinosa Kuntze) (SMT-T) prepared by sulfomethylation and chelating of the extract from pod shell of tara, were studied. The results show that SMT-T could be used as drilling mud thinner and the drying method of SMT-T as well as its addition amount (0.5%-2.0%) have no significant influence on the viscosity reducing rate (VRR). When the temperature is 180℃ and the addition amount of SMT-T is 2%, the VRR is up to 80% and it is 82.5%-86.4%, when the temperature is 200-220℃. The quality indexes of SMT-T are exceeding those in the industry standard SY/T 5091-1993. SMT-T is suitable for the drilling deep well, gas well and high density well in the temperature range of 180-220℃.
Key words: drilling mud thinner, sulfomethylated tannin of tara, evaluation of the performance
