FIELD: production of liquid and fluid gaseous media from wells. SUBSTANCE: invention specifically deals with processes of production of hydrocarbons with subsequent separation of materials extracted from wells. It can find use in process of development of gas-condensate and gas-condensate-oil fields. Technical result of invention lies in provision for inclusion of wide fraction of volatile hydrocarbons ( fraction C2+C3+C4 ) in marketable products and their delivery to consumer. Stratal gaseous mixture extracted from cluster of wells and collected at cluster collection point is cleared from solid, liquid and gaseous impurities and separated into two phases: methane-ethane phase( (C1+C2) ) and propane- butane phase ( (C3+C4). Methane-ethane fraction is pumped into main gas line. Propane-butane fraction is pumped into same gas line by means of multistep cyclic treatment. On delivery to consumer gas mixture is separated into fractions and components if necessary. EFFECT: provision for inclusion of wide fraction of volatile hydrocarbons in marketable products.
