【摘要】 在世界常规石油资源紧缺的局面下,稠油将成为常规石油资源的重要接替资源。稠油富含胶质和沥青质,密度大,黏度高,流动性差,其开采和输送困难。因此解决稠油的降黏问题,对稠油开采和管输等具有重要意义。本文总结了稠油化学降黏技术中乳化降黏技术的研究和应用。并分析了稠油降黏剂的发展趋势。更多还原

【Abstract】 With the shortage of conventional oil reserves, heavy crude oil will become the substitute resource of conventional oil. Due to high colloid and asphaltene content, viscous crude oil has a high density and viscosity and poor flow-ability that it’s difficult for its exploration and transportation. So solving the viscosity reduction prob-lem has an important meaning in the exploration and pipeline transport of viscous crude oil. The passage summarizes the research advance and application of the technique of viscosity reduction by emulsifying of heavy oil, and analyses the developing direction of emulsion viscosity reducers.更多还原
