Studies on the hydrothermal upgrading of bitumen in the range of supercritical water were carried out for developing of a new on-site visbreaking technology combined with SAGD process. It should be emphasized that in the hydrothermal visbreaking, neither hydrogen gas nor catalyst is used, and in the alkali hydrothermal visbreaking, neither CO_2 nor H_2S is issued. A combined system with SAGD can utilize the hot wastewater as steam for injection.A continuous flow reactor for hydrothermal upgrading bitumen of 0.1 b/d was operated. Fundamental and important data for the new process were obtained. (1)It was found that the influence which the passage time of oil exerts on the hydrothermal reaction by extending the length of the pipe by 1.5 times.(2)Bitumen was easily converted to light oils with a conversion ratio of more than 85%, with simultaneous reduction of sulfur to ca. 1/2 and coke production of ca. 8%, at the reaction condition of 430℃ reaction temperature and 15 min reaction time with 1 mol dm^<-3> KOH solution at 20% water fill. The oil produced at the above-mentioned reaction condition was sufficiently light for pipeline transportation. (3)It was studied about the flow behaviour of oil and water in the vertical -type cylinder under the region of sub critical water to develop the new equipment which separates fluid after the reaction to oil and water phase.

为开发与SAGD工艺相结合的现场减粘裂化新技术，开展了超临界水水热改质沥青的研究。水热减粘裂化不使用氢气和催化剂，碱热减粘裂化不产生CO_2和H_2S。与SAGD组合的系统可以利用热废水作为蒸汽注入。连续流动反应器用于0.1 B/d的沥青水热改质。获得了新工艺的基础数据和重要数据。(1)It发现油的通过时间对水热反应的影响通过将管的长度延长1.5倍来实现。（2）沥青易于转化为轻质油，转化率可达85%以上，同时硫含量降低到约10%。1/2和焦炭产量约。在反应温度430℃、反应时间15 min、加水量20%、KOH溶液用量1 mol·dm ~（-1）的条件下，产率可达8%<-3>。在上述反应条件下生产的油对于管道运输是足够轻的。(3)It为研制油水反应后流体分离的新装置，对亚临界水区油水在立式圆筒内的流动特性进行了研究。
