摘要
以纳米铜和供氢剂为主要裂解剂,对辽河油田超稠油开展催化裂解改质降黏实验,在纳米铜质量分数为0.05%、供氢剂质量分数为0.1%、反应温度为180~270℃的条件下反应24 h,超稠油的黏度(50℃)从1.55×10^(5)mPa·s降为2 122~6 684 mPa·s,降黏率达到95.69%~98.63%。原油的族组分分析表明:裂解后原油的饱和烃、芳烃含量明显增加,胶质和沥青质显著降低。原油全烃谱图分析表明,原油的轻重比也大幅度增高,实现了超稠油原位改质降黏作用,改善了超稠油流动性,提高了原油采收率。
This study used copper nanoparticles and hydrogen donor additives as main agents for aquathermolysis to carry out a series of quality improvement and viscosity reduction experiments on extra-heavy crude oil from Liaohe oilfield.With 0.05%and 0.1%of copper nanoparticles and hydrogen donor additives respectively,the reaction was carried out under 180-270℃for 24 h,resulting in a viscosity reduction rate of up to 95.69%-98.63%,having plummeted from 1.55×10^(5)mPa·s to 2122-6684 mPa·s.Group composition analysis of the crude oil suggested that,at the end of the aquathermolysis,the content of saturated hydrocarbons and aromat-ics in the crude oil increased,while the content of resin and asphalt decreased.The total hydrocarbon spec-trum analysis of crude oil showed that the weight ratio of crude oil increased greatly,and the effect of in-situ modification and viscosity reduction of super heavy oil was realized,and the fluidity of super heavy oil was im-proved and oil recovery was enhanced.
