摘　　要：水驱气藏在己投入开发的气田中占很大的比重,对水驱气藏进行深入研究具有重要的理论意义和应用价值。本文对水驱气藏合理产量的研究是从单井研究出发,首先介绍了常规气井配产方法,并在掌握气藏地下、地面有关资料的基础上,建立了考虑气井积液,气液对管壁的冲蚀作用,底水锥进,地层气流的速敏效应和计划产量众多因素的综合配产模型,然后,根据气井的动、静态资料确定了解气井合理的生产压差。最后,利用实例气井资料进行计算,并验证该模型,认为该模型在这类气井配产中是适用的。能为现场配产提供一定的指导依据。Water flooding gas reservoirs account for a significant proportion of developed gas tlelds, in-depth stuoy on me water flooding gas reservoir has great theoretical significance and value. In this paper, reasonable production of water flooding gas reservoir was studied based on single well production： The allocation method of conventional gas wells was introduced. Based on the related information of gas reservoir, considering many factors including gas well liquid loading, gas-liquid erosion on the wall, bottom water coning,pressure-sensitive effect and scheduled production, integrated allocation model was established; Then reasonable production pressure difference of the gas reservoir was determined according to gas well dynamic and static information. Finally, example calculation was carried out with the gas well information, and the model was verified. It＇s pointed out that the model is applicable for allocation of such gas wells, can provide a basis for guiding allocation.
