Problems of reservoir stratified heterogeneity effect on the efficiency of thermal-steam treatments of well bottom zone are considered. By calculations it is shown that the negative effect of reservoir heterogeneity in many cases can be neutralized at thermal-steam treatments of well bottom zone through the mechanism of heat exchange between the permeable and impermeable layers. For a fixed volume of steam injection, there are optimal values of the compartmentalization and sand content factors i.e. such ones, at which technological efficiency of thermal-steam treatments of well bottom zone is maximum.
