Abstract: Associated gas is produced in the production of offshore oil platforms. In order to ensure the safety of vent system,flare system is an indispensable safety facility for oil production platform. With the national demand for clean energy,the demand for oil field production planning and the national requirement for “green and low-carbon” development,aiming at the problem of large amount of natural gas venting on the oil production platform in an oil field in Bohai Sea,the amount of flare gas was effectively reduced,and the methane emission was controlled through the diagnosis and analysis of the flare gas system and the implementation of process optimization and transformation.

Key words: oil production platform, flare gas, venting, resource, economization
