摘要
针对凝析气在压力降低时存在相态转换的特点,建立了用试井分析解释凝析气井动态参数的新方法,研究了实用的试井理论图版。可解释出凝析气井的表皮系数、污染(或改善)区域半径和该区域的凝析油含量分布,以及近井区域渗透率、地层渗透率等,可为凝析气藏开采提供可靠的动态参数。最后通过应用实例给出了解释凝析气井各有关动态参数的具体方法。
Since condensate gas changes its phase state when pressure declines, a new method to analyze and interpret the dynamic parameters for condensate wells through well testing has been established, and practical well testing theory plate has been studied in this paper. By this method, parameters such as skin factor, polluted (or improved) area semidiameter, condensate oil content distribution, permeability around wells and formation permeability can be interpreted to provide reliable dynamic parameters for condensate gas recovery. At the end of the paper, a practical case is given to explain the concrete method for condensate well dynamic parameters interpretation.
