摘要：对塔拉豆荚壳经浸提、磺甲基化、络合等工艺制备的塔拉磺甲基化单宁(SMT-T)的性能进行了初步研究,结果表明:SMT-T用于钻井泥浆稀释剂是可行的;SMT-T的干燥方式及其添加量即0.5%和2.0%对钻井泥浆降黏率无明显差异;当温度为180℃、加入2%的盐,其降黏率在80%以上;当温度在200-220℃时,其降黏率为82.5%-86.4%;SMT-T质量指标测定超过现行行业标准SY/T5091-1993《钻井液用磺化栲酸》。SMT-T适宜在180-220℃的深井、气井、高密井等使用。
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 resuhs 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℃.
