实现低压气井增压开采的喷射引流技术

长庆气田经过多年开发,间歇气井逐年增多,给生产带来了很多问题,为此提出了一种喷射引流技术,在不借助外来能源的情况下,利用高压气井自身能量带动低压气井生产,研发了新型喷射装置,在长庆气田集气站开展了试验,效果良好,证实该技术切实可行,可降低生产成本,延迟增压开采时间,具有在现场生产推广应用的价值,同时建议在单级喷射效果不佳的情况下,采用多级喷射技术,实现低压气井正常外输。

Injector technology used in low-pressure gas well by increasing pressure for production

In Changqing gas field after many years development low-pressure gas wells increased gradually so result in a lot of production problems.In this paper a new injecting tehnology was introduced that can increase the pressure of low-pressure gas well by highpressure gas well without other power.The injector was devolped and tested in field,and the effect can prove that the technology was feasible,economic and valuable.In addition,the pater introduced a multi-speed injecting technology that can inject gas step ...
