Abstract: To address the problem of insufficient associated gas and insufficient flow rate to meet the requirements of compressor commissioning and start-up in a certain oil field in the South China Sea,by studying the structure and principle of the compressor,the key points for low gas flow commissioning were identified,and a series of transformation measures were taken. The commissioning and operation of the gas compressor was completed under the condition of low gas flow,and the operation of the turbine generator in natural gas mode was successfully achieved,saving a lot of costs for the oilfield.

Key words: natural gas, compressor, commissioning
