FIELD: oil and gas industry. ^ SUBSTANCE: method for determining oil-and-gas saturated intervals involves removal of slurry and gas diluted in drill fluid, analysis of that gas and relation of gas logging to certain depths. At that, slurry is removed during well drilling. Oil hydrocarbons are extracted from slurry samples. Well-logging curves are built for hydrocarbons C5+ highest. Connection of hydrocarbon logging is performed as per anomaly of hydrocarbon compound at header - not header boundary. ^ EFFECT: improving accuracy of prompt extraction of producing intervals of headway when drilling deep oil and gas wells. ^ 2 cl, 2 dwg, 5 tbl |
