摘　　要：井筒积液是产水气井不可避免的现实问题,深入了解其开井生产过程中液面的变化规律,对选择合理的排水采气工艺是非常必要的。在前人理论研究的基础上,主要对产水气井开井后液面的变化规律进行了研究,得出了开井瞬间井筒液面距井口高度随开井时间的变化关系,采用油田现场数据对该变化关系进行了计算验证。计算发现,该变化关系能够比较真实地反映现场生产实际情况,在该前提下对影响气井开井瞬间井筒液面变化的各因素(操作因素、气藏因素和流体因素等)分别进行了敏感性分析,为含水气井在实际生产中制定合理的工作制度提供了理论依据,对现场应用具有一定的指导作用。Fluid accumulation in wellbore is an unavoidable problem for water-production gas well, therefore it is necessary to know fluid level change during production in order to select reasonable drainage and production technique accordingly. This paper studied the fluid level change after opening water-production gas well. On the basis of existing theories, the relationship between fluid level and time during opening was obtained and verified by field data. Calculating results show that it reflects the actual production condition. The impacts of operation condition, gas reservoir condition and fluid condition were conducted. All these provide theoretical basis for a reasonable working system for water-production gas well in actual production.
