A method for secondary opening of productive formations in hydrocarbon deposits

Inventors

1. The method for secondary opening of productive formations of wells in hydrocarbon deposits involves injecting, during the process of perforating and blasting operations in the interval of the well with a temperature below the temperature of the onset of crystallization of the saturated hydrocarbons contained in the fluids of the formations being opened, a liquid with a density lower than the density of the saturated hydrocarbons contained in the fluids of the formations being opened.
2. The method according to paragraph 1, characterized in that during the process of secondary opening of the productive formation and the emergence of communication between the wellbore and the productive formation, the fluid of the formation being opened, containing saturated hydrocarbons and entering the wellbore, cannot rise into the interval of the wellbore with a temperature below the temperature of the onset of crystallization of saturated hydrocarbons, crystallize and thereby become the cause of an incident or accident during the process of performing perforating and blasting operations, respectively.
