浅谈塔里木油田放空天然气回收措施

Recovery Measures of Vented Gas in Tarim Oilfield

为最大限度回收塔里木油田的放空天然气,节约能源,减少大气污染,2008年塔里木油田公司主要针对塔里木油田的轮南天然气处理站、桑南天然气净化处理厂2套天然气处理装置的天然气放空原因进行调研。通过到现场收集资料,与现场操作人员沟通交流,深入了解2套处理装置的生产运行现状及存在问题并进行深度探讨,调研得出造成天然气放空的原因主要是装置的总处理能力不足和处理工艺不完善。由此通过提升装置的集气、增压、制冷能力以及新建部分设施来完善天然气处理工艺,保证装置稳定、生产安全且天然气不放空。因此,提升装置的处理能力是解决天然气放空问题的有效途径之一。

In order to recover the vented gas in Tarim Oilfield as much as possible,save energy and reduce air pollution,Tarim Oilfield Company researched reasons of gas venting in natural gas treatment units of Lunnan gas treatment plant and Sangna gas purification plant in Tarim Oilfield in 2008. Relative information was collected at the site and communication was conducted with operating personnel,deeply analyzed were operation conditions of the units and some problems occurring in their operation and analysis results suggest that insufficient treatment capacity of the units and imperfect treatment process result in gas venting. Therefore,enhanced were gas gathering,pressure boost and refrigeration capacity of the units and some facilities were extended to perfect gas treatment process,assure proper and safe operation of the units and no gas venting,which shows that enhancing gas treatment capacity of the units is one of the most effective ways for resolving the problem of gas venting.
