摘　　要：分配性能是评价气体示踪剂应用效果的重要标准之一,分配性越好,应用效果就越好。利用高温高压反应釜,在不同类型及矿化度的地层水溶液中进行气体示踪剂分配性实验研究。实验结果表明:4种自然环境的地层水对于SF6溶解的抑制作用均大于对CO2的作用;在不同类型地层水溶液,SF6在氯化钙水型中分配性能最好;在不同矿化度下的重碳酸钠溶液中,范围在0-2 000mg/L时SF6的应用效果最佳。Distribution property is one of the most import standard to evaluate the application effect of gas tracer.The better the distributivity,the better the application effect.Making use of high temperature-high pressure reactor,the experimental study of the distributivity of gas tracer was carried out in different types and salinity of formation water.The results show the stronger inhibition of sulfur hexafluoride dissolution than that of carbon dioxide in four types of natural formation water.Among different types of formation water,the distribution property of sulfur hexafluoride is the best in calcium chloride solution.The effect of application of sulfur hexafluoride is the best when the concentraion of sodium bicarbonate solution is 2 000 mg/L.
