摘要/Abstract

摘要： 轮古稠油黏度高、流动性差, 主要采用掺稀油的方式进行开采, 在实际生产中, 这种方式逐渐暴露出
稀油需求量大、价值被拉低、运输和处理成本偏高等问题。在模拟自喷井举升的条件下, 选取合适的水基降黏剂对
轮古稠油乳化降黏进行了实验研究。实验结果表明: 水基降黏剂将黏度3 16 0 0mP a·s的掺稀稠油转变成黏度不超
过4 0 0mP a·s的稠油拟乳状液, 降黏率达到9 8. 7%, 降黏后的稠油拟乳状液具有良好的动态稳定性, 易于脱水。

Abstract: Lungu heavy oil was mainly exploited by mixing light oil due to its high viscosity, however, it brings about some other problems (e.g. great demand for light oil, low cost efficiency, high expenses in transportation and processing). The simulation test of artesian flow with the appropriate emulsifier demonstrates Lungu heavy oil can be transformed into pseudo emulsion, and its viscosity decreased from 31 600 to less than 400 mPa•s, with a decreasing rate of 98.7%. The pseudo emulsion has both favorable dynamic stability and dehydrating property.

Key words: Lungu heavy oil, Viscosity reduction by emulsification, Viscosity reduction in well pipe, Pseudo emulsion, Viscosity decrease rate
