在中国石化西北油田分公司中型试验装置上采用中国石化石油化工科学研究院研制的催化降黏剂对塔河 TH12196单井稠油的降黏作用进行了考察。结果表明：当反应温度为160℃、反应时间为6 h、催化降黏剂加入量（w）为1.5％时，稠油降黏率达到54.5％；催化降黏率较热降黏率高51.4百分点，且降黏后稠油中重质组分含量减少，轻质组分含量增加；在稠油催化改质处理过程中，分子中较弱的化学键发生断裂，从而使稠油分子聚集体变小，产生不可逆降黏作用。

The field test for viscosity reduction of Tahe TH12196 heavy oil by hydrothermal catalyt-ic process was conducted in the pilot plant of Northwest Oilfield Company,SINOPEC using a catalytic viscosity reducer developed by Research Institute of Petroleum Processing. The results show that the viscosity of Tahe oil is reduced by 54.5% after catalytic modification at the conditions of reaction time of 6 h,160 ℃ and the viscosity reducer dosage of 1.5%,51.4% more than that of hydrothermal method, while similar to the results of laboratory. After the modification,the heavy components are decreased and the light ones are increased. The breakage of weaker chemical bond between molecules leads the composition changes of heavy oil,resulting in smaller aggregations and irreversible viscosity reduction.
