摘要
利用长岩心流动试验仪,研究酸化缓蚀剂对岩心损害程度及深度的评价,以便为筛选酸化缓蚀剂提供更全面的参数依据.文中对仪器试验原理进行介绍,选取了典型试验进行分析,提出了选择缓蚀剂必备条件.
Damage degree and depth of acidizing corrosion inhibitor to core are studied by using long-core flow tester,which can supply favorable and complete data for screening acidizing corrosion inhibitors.The paper introduces testing principle of the instrument, analyses typical testing result,proposes prerequisites of corrosion inhibitor selection.
