摘要:: 对一些边远油井生产的气质较富、产量较低的油田伴生气进行回收处理,这对于充分利用资源、满足生产及民用用气具有十分重要的意义。这部分天然气的气量少,距离主干线远,如何经济地回收处理是一个需要认真研究的问题。文章通过对比油田伴生气处理的常规工艺和复叠制冷工艺的优缺点,阐述了复叠制冷工艺是CNG母站与轻烃回收装置合建站的最优方案,解决了边远油井生产的油田伴生气回收处理问题。
In order to fully utilize resources and supply enough gas for production and civil usage, it is very important to implement recovery and treatment of the associated gas from some remote wells with low gas output. By contrasting the convenient process with cascade refrigeration process, it is shown that the cascade refrigeration process is the optimal scenario for the joint station of CNG primary treatment and light hydrocarbon recovery unit to solve the recovery and treatment problem of the associated gas from some remote wells.
