Laboratory Studies of Liquid Hydrocarbon Displacement from a Porous Medium Model under the Effect of an Electromagnetic Field

The article studies the displacement of liquid hydrocarbons from a model of a porous medium using the example of oils with different contents of asphaltene–resin–paraffin substances, as well as dielectric properties, when an electromagnetic field of a certain frequency is applied to an oil-saturated model. The results of experimental studies are presented, showing the correlation of an increase in the oil displacement coefficient with the content of asphaltene–resin–paraffin compounds in oils and the dielectric parameters of oils. It is demonstrated that a high content of polar components of oil (asphaltenes and resins) leads to the greatest increase in the oil displacement coefficient, and with an increase in the paraffin content, an increase in the oil displacement coefficient decreases. Also, with an increase in the value of the dielectric loss tangent, there is an increase in the growth rate of the oil displacement coefficient. It was found that for all studied oils, a positive increase in the oil displacement coefficient is observed in the presence of an electromagnetic field.
