摘要
对碱金属硼氢化钠作为黄原胶溶液的热稳定剂进行了研究 .结果表明 ,硼氢化钠浓度为 80~ 3 2 0 mg/L,合成海水盐浓度为 4 %和甲醛浓度为 0 .4 %时 ,在无氧条件下 ,黄原胶溶液 85℃高温处理 60 d,其溶液性能基本保持不变 ,粘度损失仅为 2 %~ 6% .
The results of reseach on alkali metal sodium borohydride as viscosity stabilizer of Xanthan gum solution at elevated temperature are reported. The experiment showed that property of Xanthan gum solution maintained stable on the whole and viscosity of the solution only lost 2%~6% when storing at 85℃ for 60 days after removing oxygen and adding 80~320mg/L sodium borohydride, 40g/L of synthetic sea water and 4g/L of commercial formaldehyde to the solution. The results proposed a new way for Xanthan gum application in the tertiary oil recovery at elevated temperature reservoirs.
