Testing research about the influence of electrostatic field on crude oil's viscosity

A significant problem in increasing pipeline's oil transporting efficiency is to reduce crude oil's viscosity.There are many viscosity reducing methods but all exist some shortcomings more or less.Therefore, a new viscosity reducing method should be found out to come up to viscosity reducing result.Thrpugh a series of indoor tests, electrostatic field has been used in crude oil treatment to improve its rheological behavior to achieve the goal of viscosity reduction.At the same time, make a preliminary analysis on the action mechanism of crude oil treatment in electrostatic field.It is stated by test that the flow resistance of the crude oil treated in electrostatic field can be reduced with its molecule in ordered arrangement, avoid a constitution of grain crystallized molecule, its viscosity may be reduced by about 19%, raise pipeline transporting efficiency effectively and reduce energy consumption.Furthermore, it is simple in method and convenient in production application.
