FIELD: increasing pressure of natural gas in the course of its transportation. SUBSTANCE: main gas line is connected with gas transfer apparatus of compressor station by means of suction and delivery pipe lines; compressor station includes forced oil supply unit. Oil cooler of this unit is divided into cavities for cooling agent and for oil to be cooled by means of heat-transfer surface. Suction pipe line of main gas line is connected with inlet and outlet pipe unions of cooling agent cavity of oil cooler. Suction pipe line is provided with bypass line fitted with shut-off member. Besides that, connection of suction pipe line with pipe unions is made by means of branches with member mounted between them for forming local hydraulic resistance. This member is made in form of converging tube, diffuser being mounted after converging tube.
