随着衰竭式开发的加深,由于地层压力下降,举升能量降低,以致气井产量达不到临界携液流量,井筒积液严重。气井积液已经严重影响到气井的正常生产和气田产能发挥。泡沫排液采气技术具有施工容易、见效快、成本低等优点,对积液严重的凝析气井具有更重要的意义。本文结合两种新型适用于高含凝析油井(20%～90%)的泡排剂的现场应用,简述了该工艺的基本原理,分析了通过应用该工艺取得的经验和认识。 With the deepening of depletion development, due to the decrease of formation pressure, the lift energy is reduced, so that the gas well production can not reach the critical carrying liquid flow and the wellbore fluid is serious. Gas well effluent has seriously affected the normal production of gas wells and gas field capacity to play. Bubble drainage gas production technology has the advantages of easy construction, quick response, low cost and so on. It has more important significance to the condensate gas well with serious effusion. In this paper, two new types of effervescent agent for condensate oil wells (20% ~ 90%) are briefly introduced in this paper. The basic principle of this process is briefly described. The experience and knowledge gained through the application of this technology are analyzed.
