气田放空天然气减排技术探讨

随着低碳发展理念的不断深入,放空天然气带来的资源浪费与温室气体排放问题日益成为气田节能减排的关注重点之一。文章结合气田放空天然气排放特点,着重探讨国内外回收利用现状,在分析西南油气田减排技术需求的基础上提出适宜的减排技术建议,包括：开发井口放空气撬装式回收装置,开展增压机放空天然气减排技术研究,开展火炬气减排技术研究。通过对此类技术群的继续开发与应用,为气田下一步减排行动提供技术参考。

A Discussion of the Emission Reduction Technologies about Natural Gas Venting in Gas Field

Associated with the widespread of "low-carbon" development concept, the waste of resource and GHG emission from natural gas venting has become a highlight of energy conservation and emission reduction in gas field. This paper summarizes the domestic and international state of art in vented gas recovering. By analyzing the emission characteristics of the vented gas and the technical demands of gas field in southwest, further reasonable suggestions on emission reduction are proposed as following: developing skid-mounted equipment to recover the venting gas from natural gas well, studying on emission reduction technologies of the venting gas and flare gas, etc. The sustained development and application of the listed technologies would provide technical reference to the future endeavor in emission reduction for gas field.
