METHOD FOR DETERMINING NATURE OF INTER-STRING GAS SHOWS OF WELLS OF MULTIFORMATION OIL-AND-GAS CONDENSATE DEPOSITS |
摘要 |
FIELD: oil and gas industry.SUBSTANCE: in addition, analysis of isotopic composition of carbon of sum of hydrocarbons C-Cis performed and limits of values of isotopic composition of carbon, methane and isotopic composition of carbon of sum of hydrocarbons C-Cfor reference horizons are determined. Tables and/or graphs represent ranges of values of isotopic composition of gases from reference horizons and gases are represented from inter-string space of wells or drilling fluid; as per the degree of similarity or coincidence of the above ranges of those values (or individual points) there evaluated is nature of investigated inter-string gas shows.EFFECT: improving reliability in determination of nature of inter-string gas shows.1 ex, 2 tbl, 1 dwg |
