Research on the High-Frequency Electromagnetic Acoustic Heating of an Oil Reservoir with Further Pumping of a Solvent

Resumo

A method involving high-frequency electromagnetic and acoustic fields (for heating) and subsequent pumping of a low-viscosity solvent is proposed to affect high-viscosity oil reservoirs. The system of heat conduction, peizoconductivity, and diffusion equations is solved with corresponding initial and boundary conditions by the method of finite differences with an implicit scheme. The dependence of the found solutions (oil reservoir temperature fields, bottomhole temperature dynamics, solvent flow rate change) on such parameters as the bottomhole pressure, the initial oil viscosity, and the high-frequency electromagnetic field generator power is considered.
