摘　　要：富气是指富含C3、C4以上组分的天然气,具有较高的利用价值。准噶尔盆地已开发的7个气田均为凝析气藏,凝析油稳定工艺中排放的富气压力低、流量小且不稳定,回收利用较为困难。文章介绍了近年来准噶尔盆地气田富气回收所采用的分子筛脱水、加热稳压就近作燃料,二次循环处理等几种工艺技术,并对其适应性进行了分析。Rich gas referred to the natural gas rich in the component of C3 and C4 which is of high value in use.7 explored gas fields in Junggar Basin are all condensate gas reservoir but recovery and utilization of the rich gas is very difficult due to the low pressure,small flow rate and weak stability of the gas obtained from condensate oil stabilizing process.Different rich gas recovery technologies are introduced such as molecular sieve dehydration,using as fuels nearby after heating and pressure stabilization and secondary cycling treatment and their adaptability are analyzed.
