摘要： 用11 个计算模型对准噶尔盆地凝析气压缩因子进行计算及对比分析,找出了既适用于凝析气又适用于普通天然气的早期预测压缩因子的计算模型,同时提出了AGA8-92DC 模型、HTP 模型、SHBWR 模型、SRK 模型和低压Z模型修正方法,计算结果最大平均误差从5.64%降为0.92%,大幅提高了预测准确度。

Abstract: Eeleven calculating models are applied to calculating compressibility factor of condensate gas reservoir in Junggar basin and making a correlation of the results. The calculation model is found for early forecasting compressibility factor of both common natural gas reservoir and condensate gas reservoir. Also, the correction method of compressibility factor is found for AGA8-92DC model, HTP model, SHBWR model, SRK model and low-pressure Z-model. The calculated results show that the maximum average error is reduced to 0.92% from 5.64% with greatly increasing accuracy of such a prediction.
