摘要
采用自制的油泥分离剂通过热化学分离法处理聚驱油田现场产生的含聚油泥。采用正交实验得到的最佳工艺参数为:剂泥比2.0 m L/g,反应温度80℃,反应时间30 min,搅拌转速500 r/min,在此工艺条件下原油回收率为92.08%。利用支持向量机运算法(SVM)建立模型,分析了各工艺参数之间的交互作用,得出优化后的含聚油泥处理工艺参数为:剂泥比2.5 m L/g,反应温度80℃,反应时间34 min,搅拌转速530 r/min,理论上的最高原油回收率为94.76%。对于模型优选出的工艺参数进行了5组验证实验,平均原油回收率达94.50%。采用优选工艺参数处理3种不同来源的含聚油泥,原油回收率均高于90%。
The polymer-containing oily sludge in polymer flooding oil field was treated by thermochemical separation process using self-made oil-sludge separating agent. The optimum processing parameters obtained by orthogonal design experiment were as follows：agent-sludge ratio 2.0 mL/g,reaction temperature 80 ℃,reaction time 30 min and stirring speed 500 r/min. Under these conditions,the recovery rate of crude oil was 92.08%. The interaction between these processing parameters was analyzed by support vector machine（SVM）algorithm,and the optimized processing parameters were as follows：agent-sludge ratio 2.5 mL/g,reaction temperature 80 ℃,reaction time 34 min and stirring speed 530 r/min,and the theoretical best recovery rate of crude oil could reach 94.76%. The processing parameters optimized by the model were tested for 5 times,and the average recovery rate of crude oil was 94.50%. When polymer-containing oily sludge samples from 3 different sources were treated under the optimized processing parameters,all the recovery rates of crude oil were higher than 90%.
