摘　　要：建立了凝析气在多层气藏中的不稳定渗流模型,用差分解法求出了三层气藏井底压力的数值解,绘制了试井理论图版及各种气藏边界条件的试井理论曲线,为多层气藏的试井分析提供了理论基础,并解决了目前凝析气藏开发的实际问题,通过多层凝析气藏试井解释可为气藏开发提供可靠的动态参数,最后给出了应用实例。This paper constructs an unstable flow model of multi-layer condensate gas reservoirs. It calculates the value of the bottom hole pressure in 3-layer gas reservoirs using difference method, plots a chart of well test theory and curves of well test theory of various gas reservoir boundaries. It provides theoretical evidence for well test analysis of multi-layer gas reservoirs, and solves the problems in the present development of condensate gas reservoirs. Well test interpretation of multi-layer condensate gas reservoirs can provide reliable dynamic parameters for gas reservoirs development.
