Reducing the viscosity of heavy oil is of great significance in petroleum production and transportation. In this paper, we studied the reduction of viscosity of crude oil under the irradiation of a 532 nm laser in which the variation of current, temperature, and viscosity was also studied and discussed. Owing to the photolysis-product absorption and order-n multiphoton absorption, both the current and temperature increased over time with the laser turned on, simultaneously, leading to the breakage of chemical bonds and the drop in viscosity. With its advantage of rapidness, collimation, and no contact, laser technology may serve as a powerful tool to reduce the viscosity of crude oil.

应用532 nm激光降低原油粘度

降低重油的粘度在石油生产和运输中具有重要意义。在本文中，我们研究了532 nm激光辐照下原油粘度的降低，其中还研究了电流，温度和粘度的变化。由于光解产物的吸收和n级多光子的吸收，电流和温度都随着激光的开启而随时间增加，同时导致化学键的断裂和粘度的下降。凭借其快速，准直和无接触的优势，激光技术可以作为降低原油粘度的强大工具。
