页岩气开采放空气回收处理与利用研究

Research on treatment and reutilization of vent gas during the exploitation process of shale gas

随着油气开采技术的不断发展,国内外相继发现了一种新的能源资源-页岩气。在开采页岩气过程中试采放空气直接放空成为一个普遍的问题。本文总结了常规气田放空气和煤层气的回收利用方案,并通过反复调研和论证,采取CNG技术回收页岩气开采放空的天然气,不仅实现了节能减排,降低了对环境的污染,同时还产生了明显的经济效益。

With the continuous exploration of oil and gas, a novel resource of shale gas has been developed. The treatment of vent gas during the production test of shale gas has been a serious problem. This paper summarized the vent gas scheme of the regular field and coalbed gas recycling. It concluded that the CNG technology is the best method for reutilization of vent gas during the exploitation shale gas after lots of contrast and analysis. The Compressed Natural Gas(CNG)technology can not only achieve energy-saving and emission-reduction,but also reduce pollution to the environment, furthermore,it can gain good economic benefits.
