FIELD: chemistry.
SUBSTANCE: method of preparing well production with obtaining separation gas, water condensate, which is withdrawn from installation, hydrocarbon condensate, which is throttled and stabilised with obtaining stabilisation gas, water condensate, which is withdrawn from installation, and trade condensate. Stabilisation gas is subjected to catalytic methanation in presence of water steam, with application of hydrogen-containing permeate as fuel, obtained catalysate is cooled and separated into converted gas and water steam condensate, which is purified, evaporated and recycled in form of water steam for methanation. Converted gas is separated on membrane installation with obtaining hydrogen-containing permeate and purified converted gas, which is mixed with separation gas and subjected to complex preparation with obtaining trade gas and condensate, which can be directed to methanation after purification.
EFFECT: invention makes it possible to increase output of trade gas, prevent reduction of volume heat-generating ability of trade gas, as well to exclude unauthorised consumption of fuel.
