摘　　要：选择新疆克拉玛依油田三采试验区T2 k1克二中区T2 k1的实际储层砂 ,在 30℃、5 0℃下 ,按 1/ 2 (g/ml) ,1/ 5(g/ml) ,1/ 10 (g/ml)三个固 /液比分别与 1.6 %wt的Na2 CO3 溶液和 1%wt的NaOH溶液反应 8h ,12 0h ,36 0h。监测了反应前后碱液浓度的变化 ,计算了各个条件下的绝对碱耗量。结果表明 :随着固 /液比减小和温度升高 ,储层砂的绝对碱耗量增加 ;1%wtNaOH的碱耗量大于 1.6 %wtNa2 CO3 的碱耗量 ,但碱剂类型、反应时间、反应温度与绝对碱耗量的关系受固Sand beds from the t 2k 1 in middle part of the second district in kelamayi oil filed was selected. Static alkali consumption tests were completed at different temperatures (30c, 50c) and solid/liquid ratios 1/2(g/ml), 1/5(g/ml (, 1/10(g/ml) for 8hours, 120 hours and 360 hours respectively. Absolute alkali consumption was calculated for each test. Results show absolute alkali consumption increases while temperature goes up and solid/ liquid ratio decreases. Absolute alkali consumption for sands in NaOH solution is much lager than that in Na 2CO 3. But the relationship between absolute alkali consumption and alkali, temperature and reaction time will be affected by solid/liquid ratios.
