Calculation of the thermal influence effectiveness on an oil-saturated reservoir
Numerical research of hot water-flooding efficiency using a heat margin is carried out. Influence of various parameters (volumetric consumption and the temperature of the water injected into a reservoir, efficiency factor of the water heating installation - injection wel system, a reservoir porosity) on the additionally obtained volumetric oil consumption (minus conditionally used oil for the hot water heating with account of the well-known efficiency factor) was carried out. It is shown that the dependence of the volume of the additionally obtained oil on the volumetric consumption of the injected water is nonmonotonic. It is established that the positive effect of the heat margin method is observed only under certain values of the reservoir porosity and the efficiency factor of the water heating installation - injection well system.
