摘　　要：随着苏里格气田的规模开发,生产时间的延长,地层能量不断递减,产水气井数量逐年增多,这严重影响了气田产能的发挥。目前,苏里格气田产水气井约占气井总量的三分之一,在众多排水采气工艺中,泡沫排水采气工艺由于其施工方便,成本低,符合苏里格气田低成本开发的基本原则,已经成为气田排水采气的主体措施,苏里格气田泡沫排水采气措施中药剂的选择,加注制度的设计都是由其特殊的工艺流程决定,经过几年的生产实践,泡排工艺在苏里格气田应用过程中解决了诸多气井产水问题。通过泡沫排水采气工艺,苏里格气田年增产气量约2.4×108m3,产生了客观的经济效益。With the increasing development scale and extending production time of Sulige gasfield,the formation energy is declining and water-producing gas wells are increasing year by year,which may affect productivity very seriously.At present,about one third of gas wells are water-producing ones.Of numerous drainage gas recovery technologies,the foam drainage gas recovery has become the main tool for this gasfield due to its convenient operation and low cost.For this technology,the selection of agents and design of injection system are determined by its special process flow.Through years of practice,it solved the problem of water production existing in many gas wells.The annual increase of gas production achieved about 2.4 ×108m3,resulting in good economic benefits.
