摘　　要：凝析油气藏在开采后期,由于地层压力自然递减加快,开采难度加大,而后期的工业及民用天然气需求量不断增加,导致凝析气藏产气量逐年缩减与天然用量逐步增多的矛盾日益明显。为缓解这一矛盾,考虑将不能输送的放空低压气进行技术增压,达到输送压力后,进入输送管道,从而增加天然气输送量,减少天然气放空对环境的污染。In late stage of condensate gas reservoir exploitation,the natural decline of formation pressure usually speeds up which poses increasing exploitation difficulties.In contrast,the need of industrial and civil gas grows continuously.Therefore the contradiction between the decrease of condensate gas production and the increase of natural gas demand is increasingly apparent.In order to solve the problem,we technically boost the pressure of low-pressure venting gas which can't be transported,and then put into the pipelines to increase the amount of natural gas which in turn reduces the environmental pollution of venting natural gas.
