基于磁场中磁核分析的原油防蜡降粘机理研究

Study on the Mechanism of Paraffin-controlling and Viscosity-reducing in Crude Oil Using Magnetic Treatment

在分析了磁场对石蜡磁性核作用的基础上，推导了磁场作用下石蜡磁性核按能级规则排列并围绕磁场进动，这种进动使石蜡分子在结晶过程中间距增大，突破色散力，防止蜡晶形成三维网状结构，加速了由于石蜡结晶成核半径减小、结晶释放潜热增多而引起的防蜡降粘效果，并进行了实验验证。

The effects of the magnetic field on magnetic nucleuses in the paraffin are analyzed in this paper, based on which the novel opinion is proposed by the author that the magnetic nucleuses in the paraffin are arranged regularly by the energy level and processing around the direction of magnetic flux density, which increases the space among paraffin molecules, reduces the London forces among crystals, and prevents paraffin molecules to form the 3D reticulation texture during that time of the crystallization. As the result of the above, the heat released during that time of the crystallization, which caused by the decreased nucleation radius of paraffin crystals, becomes more than that of the previous texture, which enhances the effectiveness in terms of paraffin-controlling and viscosity-reducing. The experiments are carried out to monitor the viscosity of the crude oil, and the new opinion is demonstrated.
