摘要:

选择新疆克拉玛依油田三采试验区T2k1克二中区T2k1的实际储层砂,在30℃、50℃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Na2CO3溶液和1% wt的NaOH溶液反应8 h,120 h,360 h。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% wt NaOH的碱耗量大于1.6% wt Na2CO3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/液比影响大。

Abstract:

Sand beds from the t2k1in 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 onsumption 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 Na2CO3. But the relationship between absolute alkali consumption and alkali, temperature and reaction time will be affected by solid/liquid ratios.

Key words: reservoir sands, absolute alkali, consumption laboratory test
