摘要
分析了三元复合驱采出系统垢的组成 ,其主要成分为硅铝酸盐 ,质量分数达 5 0 %以上 ,油的质量分数约2 0 % ,碳酸盐垢的质量分数约 10 % ,垢的质地坚硬难除 .针对这一现实研制了三元复合驱采出系统高含硅垢的除垢剂 .配制除垢剂的工艺条件为 :HCl与HF总酸度控制在 15 % ;分别加入质量分数为 0 .5 %～ 1.0 %的表面活性剂烷基酚聚氧乙烯醚 ,0 .5 %的渗透剂磺基琥珀酸二辛酯和 0 .5 %缓蚀剂 .室内试验表明 :该除垢剂的适宜温度为 60℃ ,除垢率可达90 %以上 ,缓蚀率大于 95 % .
The analysis of the composition of the scale caused by ASP flooding reveals up to 50% of silica, 20% of oil and 10% of carbonate in the composition of scale in the ASP flooding system. According to the results, a descaling agent was prepared as the follow: 0.5%～1.0 % surface active agent, 0.5% penetrating and dispersing agent and 0.5% corrosion moderator with HCL and HF 15% of the total acidity. The experimental results show that the agent can descale 90% of the scale and the corrosion delaying rate is over 95%.
