| 摘 要： | 将预测垂直水力压裂气井产能的无因次IPR模型改进后，对水平气井产能进行预测。将由传统修正等时试井分析得到的IPR曲线和由无因次IPR曲线模型得到的IPR曲线进行对比，其绝对无阻流量相差在2．1％以内，且这两条IPR曲线的误差仅约为4％。由此说明，无因次IPR曲线模型是一种经济实用的预测水平气井产能的方法。

| Abstract: | A dimensionless inflow performance relationship (IPR) model that is used to predict the deliverability of a hydraulically fractured ver- tical gas well has been modified to predict the performance of horizontal gas wells. By comparing the IPR curve generated from a con- ventional modified isochronal analysis and that generated from the new model, the absolute open flow capacity was within 2.1% of each other, and the average error between the two curves was approximately 4%. The dimensionless IPR curve model appears to pro- vide a cost-effective way of predicting horizontal gas well deliverability. |
