摘　　要：为探讨固体稠油的原位改质降黏技术,提高采收率,对其中关键因素催化剂进行研究。分别采用油溶性催化剂环烷酸铁与水溶性纳米催化剂硝酸铁,对新疆油田中的稠油固体进行改质降黏,并采用集总的分布式活化能模型(DAEM)模型对稠油固体热解过程进行分析。结果表明:环烷酸铁和硝酸铁独立作为催化剂时,对于稠油固体的降黏率分别到56.29%,45.40%;两者复配使用时,降黏率可达到97%,复配协同作用有助于集成各自优势。In order to study in-situ modification and viscosity reduction technology of solid heavy oil and improve oil re covery,the most critical factor catalyst was studied.Iron naphthenate,an oil-soluble catalyst,and ferric nitrate,a water soluble catalyst,were employed,and their separate and combined effects on viscosity reduction were evaluated.The re sults showed that,the viscosity of heavy oil was reduced by 56.29%and 45.40%respectively when the two were used as separate catalyst,while the viscosity was significantly reduced by 97%when the two catalysts were combined.The dis tributed activation energy model(DAEM)was employed to analyze the pyrolysis process of heavy oil and the synergistic effect of the catalysts helps to integrate the advantages of the two catalysts.
