FIELD: gas and oil producing and oil processing industries. SUBSTANCE: method comes to filling of reservoir with oil products and storing them in inert gas atmosphere and giving out. Prior to filling, compressed air is introduced into hydrogen sulfide- and-mercaptan-containing raw material, or oil products, or gas condensate in presence of catalysts at pressure of 0.3-3.0 MPa in amount of 0.06-0.12 nm3 per mole of hydrogen sulfide or 2 moles of mercaptans C1-C3. Solution is kept at temperature of 10-65 C for 5-180 min. After oxidizing of hydrogen sulfide and mercaptan by oxygen from air, solution is delivered into reservoir where pressure in reduced to 0.1-0.6 MPa. Waste air dissolved in raw material and containing more than 90% of nitrogen and less than 7% of oxygen is liberated forming nitrogen cushion over liquid. Alkaline water solutions of cobalt phthalocyanines are used as catalysts. NaOH, Na2CO3, Na2S, NH3 and alkanolamines are used as alkaline agents. Consumption of cobalt phthalocyanine is 0.02-0.2 g, alkaline agent is 0.1-0.6 moles per mole of hydrogen sulfide or 2 moles of mercaptans C1-C3.. EFFECT: simplified storage and reduced cost of storage. 6 cl, 3 ex, 1 tbl
