摘　　要：针对文23储气库高产、高气液比工况,在确定井筒流动型态的基础上,采用井下实测数据对6种常用模型进行综合评价及修正,优选了无滑脱压降模型,预测结果与实际数据符合率达到98%,为储气库气井采气能力的准确预测及合理配产奠定了基础。In this paper,for the condition of high production and high GWR,on the basis of the flow pattern in the tubing,by using the test data,6 models were evaluated and corrected,the No Slip Assumption was optimized as the best calculation model with a coincidence rate of 98%between the calculation and the test,which was a foundation for the accurate prediction and appropriate proration production of the wells.
