改善超重质油流动性的技术——超临界水技术

作为人类最宝贵的资源,石油在世界各国国民经济的发展中一直起着很重要的作用。但是,与天然气、煤炭等相比,石油的可开采时间最短。因此,加拿大油砂等非常规石油资源作为石油有效的补充逐渐受到人们的关注。但是,与中东原油等常规原油相比,加拿大油砂是使用性能极差的原油,从加拿大油砂提取的油砂沥青流动性非常差,很难通过管道输送的方法运输到炼油厂,因此其利用受到很大的限制。针对这一情况,研究人员利用超临界水进行了降低超重质油粘度,改善其流动性的研究工作,取得了很好的结果,可为利用加拿大油砂等非常规石油资源、保障未来能源安全起积极的作用。

Technology of improvement of super heavy oil flow —— supercritical water technology

As the most precious resource to human, oil has played a very important role in the development of national economy in the world. However, compared with natural gas and coal et al, the exploitation time of oil is the shortest. Therefore, as oil additional resources, unconventional oil resources such as Canadian oil sands are gradually by attention. However, compared with conventional crude oil such as Middle East crude oil, the perfor- mance of Canadian oil sands is poor. The liquidity of oil sand bitumen extracted from Canadian oil sands is too poor to transport to the refinery through pipeline, therefore the utilization is limited. In view of this situation, the researchers achieved good result to use supercritical water to reduce the viscosity of extra-heavy crude oil and to improve its liquidity. It can play an active role for the use of Canadian oil sands and other unconventional oil re- sources and for protection of future energy security.
