摘　　要：海上油气资源已成为中国油气资源的重要组成部分。海上油气在生产过程中,大部分低压伴生气是通过火炬燃烧后进行放空,这不仅造成了资源浪费,也不符合节能、降碳要求。本文以渤海油田某海洋石油平台火炬系统为例,对海上油田火炬气回收工艺方案进行了分析,结合海上油田火炬气回收特点,提出采用“压力控制阀+快开阀+爆破针阀+液环压缩机”的火炬气回收工艺方案,同时采用等离子随即引燃火炬替换平台现有传统火炬,既实现了平台低压火炬气的回收,又保证了火炬系统的安全平稳运行。本方案可为其他油气田火炬气回收提供借鉴,对实现海上油气绿色低碳开发具有重要的意义。Offshore oil and gas resources have become an important part of China's oil and gas resources.In the production process of offshore oil and gas,most of the low-pressure associated gas is flared and then vented,which not only causes a waste of resources,but also does not meet the requirements of energy saving and carbon reduction.Taking the flare system of offshore oil platform in Bohai oilfield as an example,this paper analyzed the flare gas recovery process scheme of offshore oilfield,combined with the characteristics of flare gas recovery of offshore oilfield,and proposed the flare gas recovery process scheme of"pressure control valve+quick opening valve+buckling pin valve+liquid ring compressor",and adopted the plasma immediate ignition flare to replace the existing traditional flare on the platform.The recovery of low-pressure flare gas on the platform is realized,and the safe and stable operation of the flare system is ensured.This scheme can provide reference for other oil and gasfield flare gas recovery,and has important significance for realizing green and low-carbon development of offshore oil and gas.
