摘要： 在气藏开发的中后期,因水平气井产水,渗流阻力增加,气体单相稳定渗流理论不再适合于气水两相流动。提出采用复合模型分析方法来分析产水时的水平气井产能,即考虑近井地带地层渗透率由于水的影响而降低,而远井地层渗透率不变;通过产能方程的建立,研究了水对气井产能的影响。

Abstract: In the middle or late period of a gas reservoir by horizontal well development process, the flow resistance may increase sharply due to producing water, and the gas flow theory of single phase isn't fit for two-phase flow of gas and water, anymore. This paper proposes composite model method to analyze the horizontal gas well productivity when producing water. It means that the near-well-bore permeability should decrease for the effect of produced water, while the permeability far from the well keeps the same. Also, this paper studies the effect of water on horizontal gas well productivity through building the productivity equation.

Key words: horizontal gas well, producing water, productivity, equation
