摘要
为了研究新型调驱剂羧甲基淀粉的封堵性能,以相同过滤体积下封堵时间的长短为封堵性能的测定指标,用溶剂法实验室自制羧甲基淀粉进行封堵实验。经研究发现其封堵性能受羧甲基淀粉浓度、溶液矿化度及放置温度和时间的影响。随着羧甲基淀粉浓度和矿化度的增加,溶液的封堵性能提高;在70℃下,溶液的过滤时间随放置时间呈现增大趋势;在90℃下相反,呈减小趋势。
To study the plugging properties of novel profile control agent carboxymethyl starch,it uses laboratory-made solvent carboxymethyl starch block experiment as the plugging time under the same filter volume to determine the performance indicators.It is found that the blocking performance is affected by carboxymethyl starch concentration,solution salinity and temperature and time of storage.With increasing the concentration of carboxymethyl starch and salinity,the sealing performance of the solution is improved;the solution of the filtration time is increasing trend at 70 ℃ and is decreasing trend at 90 ℃ with increasing storage time.
