The effective action of the instanton gas in QCD with allowance for repulsion between the instantons is found. This repulsion leads to the formation of a repulsive core of the constituent quarks. The structure of the effective action is similar to an operator expansion. The method of Bogolyubov hierarchies is used to find the coefficient functions.
