摘　　要：川东北气矿是2002年才成立的新矿,目前有生产井22口,其中6口井已开始产出地层水,使得气井产气量明显下降,以铁山12井为代表的部分气井出现了带水困难、生产极不稳定的被动局面,严重制约了生产的正常进行。通过对川东北气矿出水气井生产状况的分析,对目前6口出水井提出适宜的排水采气工艺措施,探寻适合该矿气田储层特征的有效排水采气工艺技术,为进一步的研究和应用提出建议以期实现提高气田最终采收率的目的。The northeast Gas Division is a new gas division which is founded in 2002. It possesses of 22 production wells so far, among which 6 wells have begun to produce formation water, which decreased gas production rate. Some gas wells represented by Tieshan 12 are under passive situation in terms of difficult water carrying and unstable production, which severely constrains normal operation. This paper analyses production status of water production gas wells in wells in Northeast Gas Division, explores effective dewatering gas production technology concerning reservoir characteristics in order to realize 'three stable' production and increase the use ratio of production well as increase ultimate recovery factor.
