Experimental Study On Wax Control And Viscosity Reduction Of Waxy Oil In Magnetic Field And Paraffin Inhibitor

Crude oil is a kind of complex hydrocarbon which include containing paraffin,colloid and asphaltene.With the decrease of temperature,the paraffin wax dissolved in crude oil will precipitate to form wax crystal.And as the temperature decreases further,the wax crystal gradually grows,and the connection forms a network structure which hinders the transportation of crude oil.At present,there are many methods to prevent the influence of wax crystallization on crude oil transportation,such as physical heating method,chemical additive method,magnetic treatment method and so on.Based on the theoretical and experimental research,not consider the effect of gum and asphaltene on wax crystallization,research the effect of thermal history effect,magnetic field and paraffin inhibitor on the wax of simulated oil in laboratory Including binding influence.In this paper,the microscopic characteristics of paraffin wax in simulated oil were studied by polarizing microscope digital imaging instrument,and research the relationship between the microscopic characteristics of wax crystals and the macroscopic rheological properties of simulated oil.In addition,based on the analysis theory and box counting dimension,writing MATLAB image processing program to get the fractal dimension of wax crystal morphology,and realized the quantitative characterization of the wax crystal image.Finally,through analyse the influence of thermal history effect,magnetic field intensity and paraffin inhibitor on the simulated oil wax formation,obtain the crystallization characteristics of oil wax under different treatment conditions,and hope it can provide some guidance for the study of wax crystallization of waxy crude oil.
