摘要
应用于高温(60—150℃)地层三次采油的黄原胶(Xantan gum)应维持长时期的粘度稳定性。以碱金属硼氢化物、碱金属连二亚硫酸盐或 C_3-C_5脂肪醇作为粘度稳定剂,能防止高温对黄原胶的降解作用,使溶液粘度在高温条件下长时期维持稳定。
Long-term stability in solution viscosity is an extremely important requirement for Xanthan gum employed in tertiary oil recovery from high temperature (60-150℃) reservoirs. By using alkali metal borohydrides,alkali metal hydrosulfites and C_3-C_5 aliphatic alcohols as viscosity stabilizers Xanthan gum can be made more tolerant to degradation in high temper- ature subterranean reservoirs and maintain long-term viscosity stability in solution.
