Abstract


This article took CNOOC Suizhong 36-1 reservoir cores as the research object, carried out short core acidification flow simulation test and ESEM microanalysis of four kinds of acid fluid system. By comparing several kinds of acid fluid system, we found the deep-penetration and low-damage acidizing fluid can not only effectively dissolve inorganic impurities, but also remove the emulsified oil pollution, meanwhile it could greatly reduce the secondary damage caused by acidification. The result of the acidification is most accorded with the requirements of Suizhong 36-1 oilfield.


Keywords


Aciding fluid; Acidification flow simulation test; ESEM micro-analysis
