FILTRATION-WAVE HEATING OF THE OIL POOL
Description
We have developed a mathematical model of thermodynamic processes at oscillatory movement of liquids in porous environment with consideration of heat interaction of an oil layer with surrounding breeds and phase transitions caused by dissolution of paraffin’s dissolution. We have received analytical dependences of temperatures on time, distances to well and depth, that proves an opportunity to increase of oilrecavery when influenced by periodic fields of pressure. We have suggested a bartering effect to increase the temperature in zones far from the well formation. The mathematical model is based on the equation of heat balance, taking into account the contribution of phase transitions due to paraffinization in the case when the motion of the mixture takes place in a homogeneous isotropic porous medium with constant porosity and constant density. In the work we have developed a theory of bartering effect upon oscillatory movement of fluids in porous media considering thermal interaction between the oil reservoir and surrounding rocks and phase transitions due to the dissolution of paraffins. Comparison of theoretical and experimental data has confirmed the possibility of using the first approximation for the calculation of real thermodynamic processes in the filtration-wave fields. The developed process model allows the calculation of the temperature field in the practical conditions
