HYDROCARBON FIELD ARRANGEMENT METHOD Russian patent published in 2021 - IPC E21B43/34 F25J1/00 

FIELD: gas industry.

SUBSTANCE: invention relates to gas industry and can be used in arrangement of deposits of hydrocarbons, remote from developed infrastructure, for example in conditions of extreme North, at power supply of objects remote from power grids and main pipelines. According to the method raw material for power generation is represented by natural raw gas produced at one or several wells at the deposit. Obtained raw gas is dried and purified with separation of mechanical impurities, water and condensate. Produced raw gas is liquefied at low-capacity liquefaction plant using throttle-ejector cycle and gas production equipment - compressor to maintain formation pressure. Due to this, liquefied gas of preset grade is produced and liquefaction coefficient is increased. Obtained liquefied natural gas is transported to the drilling site of the k^th well cluster in a cryogenic tank by motor transport, where it is used as fuel for a mobile gas power station at power generation. Obtained electric power is used to drive drilling rig at k^th cluster of wells. Further, low-tonnage natural gas liquefaction plant and mobile gas power plant are moved, if necessary, to new sections of deposit.

EFFECT: technical result is higher efficiency of power supply of drilling rigs due to independence of power supply from external energy sources, mobility and flexibility of power supply system.
