摘　　要：目的研究丘陵凝析气田生产开发时的产量变化规律。方法通过对动态生产数据进行拟和分析。结果气藏压力变化同时受采出程度和气藏特性控制;气田自然产能低,但压裂增产幅度大;稳产递减阶段产量下降呈指数规律变化;气田衰竭式开发时,随着压力下降,气油比上升,凝析油产量下降。结论气田实际动态储量与容积法计算储量存在较大差异。Aim To study the production history of Qiudong condensate field in the development period.Methods Dynamic producing data are fitted and analyzed.Results The pressure of gas reservoir is controlled by degree of reserve recovery and its character.Although natural deliverability is low,incremental range will be great after fracturing.In the stable production period,the decline feature presents exponential law.Gas/oil ratio will move upward and condensate output will decrease with the drop of pressure.Conclusion There is major difference between the actual dynamic reserve and the reserve calculated with volumetric method.
