摘要
对三元复合驱、聚合物驱、水驱三种驱替方式下原油性质进行分析并进行了室内熔蜡实验。结果发现,三种驱替方式下,随着油井深度的增加,蜡样的熔解速度减缓,蜡样完全熔解时间延长;当油井深度相同时,蜡样熔解速度随温度的降低而逐渐减缓;各驱替方式下油井蜡样的水浴熔蜡困难程度依次为:三元复合驱>聚合物驱>水驱;三元复合驱和聚合物驱油井热洗温度应达到70℃,水驱油井应达到65℃。
The properties of crude oil displaced were analyzed by ASP flooding,polymer flooding and water flooding,respectively.The melting wax experiments indoors was carried out.The results showed that：wax melting rate decreased and complete melt-down time grew with the increasing in well depth at each method of displacement;for the same depth,melting rate of wax sample decreased with the temperature decreasing;the difficulty of melting wax in water bath was as follows：ASP flooding〉polymer flooding〉water flooding;thermal-wash temperature for ASP flooding and polymer flooding should reach 70℃,and that for water flooding should reach 65℃.
