摘　　要：中国目前的原油对外依存度约为70%,稠油采收率的提高对国家能源的供给以及能源局势的稳定具有至关重要的作用。稠油原位催化改质技术相较于热采、掺稀等常规开采手段,具有降黏彻底、能耗较小等技术优势,从增储上产、节能降耗两个角度分析都拥有较好的应用前景。目前针对稠油原位催化改质技术的研究主要集中于改质催化剂的开发,文章总结并分析了水溶性、油溶性等6类催化剂的研究进展、性能特点和存在问题,并展望了发展趋势。针对未来油田进行稠油原位催化改质技术的规模化应用,从配套工艺和保障手段角度出发,就催化剂注入工艺技术、催化剂长周期运行能力等方面对未来所需开展的工作提出了建议,以便更早实现工业化应用。China's current dependence on imported crude oil dependence is about 70%,and it is crucial to enhance the heavy oil recovery for the national energy supply and energy security.Compared to the conventional methods(e.g.,thermal recovery,diluting with lighter oil)for the heavy oil exploitation,the in-situ catalytic upgrading method shows promising application prospects in regard to increasing the production and energy conservation due to its thorough viscosity reduction and low energy consumption.Most research about the in-situ catalytic upgrading method focused on the synthesis and testing of catalysts.In this paper,the research on heavy oil upgrading catalysts was concluded and the performance characteristics of six types of heavy oil upgrading catalysts(e.g.,water-soluble catalyst,oil-soluble catalyst)were analyzed.Several suggestions on the catalyst injection process and catalyst long-term operation capability were proposed,in order to provide references to the subsequent large-scale application of the in-situ catalytic upgrading method in the heavy oil field.
