MATHEMATICAL MODELLING OF INFLUENCE OF RADIO-FREQUENCY ELECTROMAGNETIC AND ACOUSTIC FIELDS ON OIL LAYER

Abstract

The combined effects high frequency (HF) electromagnetic (EM) and acoustic fields to the porous environment introduce interest, because appearing new cross appearance - thermoacoustic effect [1-3]. In particular, was determine appearance of augmentation effective heat-conducting of satiating porous substance at combination conducted warming with reaction waves of sound frequency (the thermoacoustic effect) [4, 5]. As a result, significantly increased the heat penetration of the layer. It is evident, interaction intensive HF EM and acoustic fields in saturated a porous medium could take place in a specific thermoacoustic influence , when thermal field shall be created in environment for account of swallowing up of energy EM and acoustic fields, appearance of distributed heat sources and an intensive heat transfer to the inland of the environment. Hence, more important of factor HF electromagnetic and acoustic influence is the really of the growth rate of the warming-up of the layer and the radius of influence compared with thermoacoustic influence. Therefore speech maybe about deep warming-up of petroleum of the oil. The application of HF electromagnetic and acoustic influence will allow to solve a lot of next practical problems: 1.To grow coefficient of oil recovery and intensification of rate development field, which contents highly viscous and highly paraffinic oils, to increase production wells. 2.To increase effective thermal methods for influence to the well bottom zone and the reservoir as a whole. 3.In injection wells to enlarge injectivity bottomhole zone and an indicator of coverage of layer by powerful.
