| 摘 要： | 基于B·A依顿和R·H加柯比利用美国27个凝析气藏的PVT实验分析资料,以及我国大港板桥、前苏联卡拉达格等凝析气田完井测试的原始地层压力、地层温度、原始气油比和凝析油的相对密度等资料,提出了应用多元回归法推导出凝析气藏衰竭式开采的采收率预测新经验公式,公式特别针对我国凝析油含量在400 g/m3以下,废弃压力大约3.4 MPa的凝析气藏.

| Abstract: | Based on the relevant data of PVT experiment made by Eaton and Jacoby who used 27 condensate gas reservoirs in America, and the well-complete testing data of original formation pressure, original temperature, original gas-condensate ratio(GOR) and relative density of condensate from Banqiao reservoir in Dagang in China, Kaladage field in the former Soviet Union, the new empirical equation on predicting recovery efficiency of condensate gas reservoir's blowdown natural depletion was presented in the paper with the multivariate statistical analysis. At the same time, the influential factors of recovery efficiency of condensate were discussed. The empirical equation was especially applied to Chinese condensate reservoirs whose content is under 400g/m~3, and whose abandonment pressure is about 3.4MPa. |
