According to method, undertaken is alternate injection of 3-6 pairs of portions of water clayey dispersion and diluted water solution of vat still residue from production of synthetic glycerine or ethylene glycol. Ethylene glycol is produced by hydration of ethylene oxide. Diluted water solution of synthetic glycerine can be injected in combination with non-ionic surface active matter. Application of aforesaid method increases zone of subjecting bed to treatment together with regulation of well injectivity profile. In addition, realization of method is made cheaper. EFFECT: higher efficiency. 1 cl, 1 tbl, 1 ex
