Abstract In recent years, China’s economy and industry have developed rapidly, which has led to an increase in energy consumption year by year. As an important strategic reserve energy, heavy oil in unconventional crude oil is particularly important for its reasonable and efficient exploitation. Adopting appropriate methods to reduce the viscosity of heavy oil is of great significance to improve the recovery of heavy oil and the efficiency of pipeline transportation. The development of viscosity reducers for heavy oil has also become the current research focus. This article reviews the research progress of the viscous mechanism of heavy oil, the synthesis methods of various viscosity reducers and their viscosity reduction mechanism at home and abroad, points out the shortcomings of the current research on viscosity reducers, and makes a prospect for its research direction.
