摘　　要：长庆气田下古气藏是一个低渗、低丰度、低产能的大型复杂气藏。随着长庆气田勘探开发工作的进一步深入,气井的出水问题暴露得越来越多,严重影响了正常生产。在产气水井动态分析的基础上,对出水对气井产能的影响问题进行了理论分析,并根据现场实例进行了计算与分析。探讨了产水气井稳产的对策。鉴于生产压差对气井产能与出水影响极大,文章在"非线性流法"的基础上,提出了产水气井合理生产压差的确定方法,并在现场得到成功应用,对实际生产有一定指导意义。Changqing gas field is a large complex gas reservoir with low permeability and low production rate. With the development of exploration and production in the field,water increment became severer and severer,which strictly affect normal production. Based on dynamic analysis for water-gas wells,some analysis have been made on the production effect for some field examples. Research has been made on solutions for stable production. Due to significant effects of production pressure drop on water increment,this paper showed calculation method for reasonable production pressure drop in water-gas well,which was based on non-linear fluid. And it has come into use in field,it was practical in production to some extent.
