ABSTRACT
Studied the possibility of using hydrogen peroxide for the purpose of increasing the efficiency of extraction of residual oil by acting on bound water. It is shown that in the process of using hydrogen peroxide in an plasts oil formation begins, the reaction of interaction of reservoir and injected fluids with it, which is accompanied by release of heat, leading to thawing of the formation and splitting of molecules of bound water. In this way, the problem of interaction of 50% hydrogen peroxide with bound water were solved by the method of field theory and quantum statistics based on the modern model of bound water. In the region of temperature above 343 K was observed the separation of the phases of bound water, including that included in it a stationary component, with the release of the free water phase. Revealed the possibility of destruction of the structure and removal of physically bound water available chemical reagents.
