摘要
地下储气库在天然气的开发和利用过程中起着重要的作用,对于新建储气库,垫层气的制作需要很大的投资。以廉价的惰性气体代替天然气作为部分垫层气具有重要的经济意义。介绍了国外以惰性气体作为垫层气的成功经验,阐述了惰性气体作为垫层气的运行机理及惰性气体与天然气相互混合的扩散原理,并提出了预防及减少混合的措施。
The underground natural gas storage(UNGS)plays an important part in gas exploitation and utilization. The cost of cushion gas is an expensive investment for a new storage. The less expensive inert gas used to substitute all or part of the base gas required in UNGS is of significant economic interest. The successful experiences of foreign countries in application of inert gas were introduced. The operation mechanism of the cushion gas substituted by inert gas and the mixing conditions of the inert gas with natural gas were described. The measures for preventing and reducing gas mixing were proposed.
