Abstract
Abstract
The article considers a two-stage exposure to the formation. At the 1st stage, the combined exposure of high-frequency (HF) electromagnetic (EM) and sonic fields on the oil formation are performed without simultaneous formation fluid withdrawal. At the 2nd stage, the HF EM field is affected on the formation and at the same time, a low-viscosity solvent is injected into it. At the 1st stage, the bottom-hole zone is strongly warmed up due to the total thermal effect of the fields and an increase in the effective thermal conductivity of the medium due to acoustic treatment on the formation. At the 2nd stage, the solvent injected into a formation withdraws heat from the bottom-hole formation zone (BHFZ) further into the field. The dependence of the oil displacement front by the solvent on the dispersion parameter of the porous medium is considered.
