摘要

Method for improved extraction of methane from solid gas hydrates is carried out through the creation of unbalanced thermobaric conditions when the pressure is decreased and heat is supported. To prevent the destruction of the collector, to save the bottomhole formation of zone and to intensify methane influx via the bottom pump and the blowout equipment the benthic sea water is periodically pumped which is saturated with hydrogen sulphide, creating hydrogen sulphide hydrates.
