影响凝析气藏衰竭式开发效果因素研究

Study on the Influence Factors of Depletion Development Effect in Condensate Gas Reservoir

对于地层能量充足的凝析气藏,多采用衰竭式开发方式实现高产,而衰竭式开发效果受多种生产因素和地质因素制约。本文针对目标凝析气藏特点,应用数值模拟方法研究井底流压、采气速度、地层渗透率和地层非均质性4种因素对衰竭式开发效果的影响,为实际生产中气井工作制度的调整以及衰竭式开发方式在凝析气藏的合理应用提供指导。

For reservoirs with enough energy, the depletion development method can be applied, and the development effect of this method is influenced by many production and geological factors. This paper mainly studied 4 factors that influence the effect of depletion development method： the bottom hole pressure, the gas production rate, the reservoir permeability and the formation heterogeneity. The studying results of this paper can be used to guide the adjustment of the gas well working system and determine the application condition of the depletion development method in condensate gas reservoir.
