With the progress in oilfield development, low-quality resources are gradually developed, and related research is focused on condensate gas reservoirs. Complex physical properties of condensate gas reservoirs and complex components of condensate gas system make well testing and productivity analysis of condensate gas reservoir difficult, which is the main reason why there has been no breakthrough in well test studies of condensate gas reservoirs for many years. In this study, based on the actual production data of the condensate gas reservoir of the Yingtai Fault Depression, we analyze the fluid phase characteristics and distribution law of the gas reservoir. Through the investigation of the preferred well test model, the well test interpretation analysis is carried out for the typical well. According to the system well test data, a one-point formula is established to predict the production capacity, and the production dynamics of the condensate gas reservoir is analyzed. This study can provide a theoretical basis for optimizing development of condensate gas reservoirs.

凝析气藏试井技术及生产动态分析

随着油田开发的进展，低质资源逐渐被开发，相关研究集中在凝析气藏上。凝析气藏物性复杂，凝析气系统组成复杂，使凝析气藏试井和产能分析困难重重，这也是多年来凝析气藏试井研究没有取得突破的主要原因。本研究基于英台断陷凝析气藏实际生产资料，分析了该气藏的流体相特征及分布规律。通过对优选试井模型的考察，对典型井进行试井解释分析。根据系统试井数据，建立单点公式预测产能，分析凝析气藏的生产动态。该研究可为凝析气藏优化开发提供理论依据。
