Abstract: Focusing on the process flow of the newly added two-stage dry gas compressor at “Deep Sea No.1” energy station in Lingshui 17-2 gas field,this paper comprehensively examines the system pressure distribution under the working conditions of platform startup,normal export operation,and pigging operations inside the oilfield. The pressure,momentum,and flow velocity of the main equipment and pipelines in the export process are verified,aiming to ensure that the pressure,momentum,and flow velocity of the export metering skid and main pipelines all meet the design requirements of the newly added compressor,and ultimately formulating a set of design methods applicable to the export process of dry gas compressors for domestic offshore platforms.

Key words: dry gas, two-stage compressor, process flow, pressure verification
