SEARCHING METHOD OF GAS AND GAS-CONDENSATE DEPOSITS

摘要

FIELD: oil and gas industry. ^ SUBSTANCE: invention refers to search of gas deposits, and can be used for finding hydrocarbon raw material in terrigenous rocks of sedimentary cover. Method involves rock sampling from oil-and-gas bearing deposits during boring process. At that slurry sampled from sedimentary cover areas adjacent to or located just above buried continental rift is used as samples; samples are treated with heated 50% salt acid solution, and occurrence of silica jelly-like mass can mean that deposits are available. ^ EFFECT: improving accuracy of definition of gas and gas-condensate deposits.
