Research on underground catalytic hydrothermal cracking and upgrading with Shengli heavy oil
Research on catalytic hydrothermal cracking and upgrading of Shengli heavy oil was conducted.Within the range of 240℃-350℃,the catalyst can improve the efficiency of hydrothermal cracking reaction by up to 52.63%,reduce the reaction temperature by 50℃,and the viscosity reduction effect remains unchanged for 30 days.A preliminary method for characterizing the efficiency of upgrading has been developed,and on-site application has achieved an oil increasing effect.
