Development of blocking remover for borehole asphaltine plugging in Tahe oilfield
摘要
Abstract
Because of asphaltine deposition,in some oil wells,there was serious asphaltine plugging. For this problem,a highly-efficient asphaltine plugging remover was developed. One component with strong penetration ability could make asphaltine deposition disperse to small asphaltine particles. Oil-soluble cationic surfactant could absorb small asphaltine particles onto the surface,which could prevent the clustering of these asphaltine particles. An efficient solvent for asphaltine was also added. The result indicated that the asphaltine plugging remover could disperse and dissolve the asphaltine deposition effectively,on the average,81.1% of asphaltine deposition could been dissolved in this asphaltine plugging remover at 70℃,the ability was better than that of samples from market,and a good result was also obtained in field tests.关键词
