摘要
由于石油资源需求的不断增长和常规轻质原油的快速开采及消耗,低品位的稠油油藏日益受到世界各国的重视,如何高效而又经济地开采和利用稠油资源成为国内外研究的热点之一。介绍了常规稠油的主要组成、物理性质,稠油降黏的方法理论及其研究进展,并论述了这些方法理论在现场的应用情况。基于前人关于掺稀降黏的研究成果,探讨并分析了植物油脚及其衍生物——生物柴油在稠油降黏中应用的可行性,丰富了稠油掺稀降黏方法体系,为稠油降黏相关研究和应用提供理论和实践支撑。从掺稀降黏工艺的发展趋势来看,认为采用与环境友好和可再生低成本的油脚皂脚所制备的生物柴油作为掺稀油是未来的一个重要发展方向。
Due to the growing demand for oil resources and the rapid exploitation and depletion of conventional light crude, low-grade heavy oil reservoirs are increasingly valued in all countries, and one of the global research focuses is how to exploit and utilize the heavy oil resources efficiently and economically. In this paper, the main components and physical properties of conventional heavy oils were introduced, the viscosity reduction methods and theories and their research progress were described, and the field application of these methods and theories was discussed. Then, based on the previous research results on mixing light viscosity reduction, the feasibility of applying vegetable oil residue and its derivative （i.e., biodiesel） to viscosity reduction of heavy oil was discussed and analyzed. It enriches the viscosity reduction method system and provides the theoretical and practical support for the research and application related with heavy oil viscosity reduction. According to the development trend of mixing light viscosity reduction technology, one important research direction is to take the biodiesel made from low cost, environmentally friendly and renewable oil foots soap foots as the diluting oil for heavy oil for future development. （1 Figure, 2 Tables, 58 References）
