| 摘 要： | 借助数值模拟方法,结合我国最大的长庆低渗透气田实际,对低渗透气田水平气井的流入动态进行了研究,系统地分析了气藏流体、储层物性以及水平井性质参数对水平气井流入动态(IPR曲线)的影响,总结出相应规律。并将二项式IPR曲线与指数式IPR曲线相结合,提出了一种新型的水平气井IPR曲线拟合方式和预测模型。在长庆低渗透气田的应用结果表明,用该曲线形式和预测模型对水平气井流入动态的拟合结果明显好于二项式拟合方式,预测结果令人满意。

| Abstract: | Taking Changqing low-permeability gas reservoir as an example the inflow performance relationship (IPR) of horizontal gas wells was discussed with numerical simulation method.The effects of reservoir liquid,formation property and the parameters of horizontal wells on the inflow performance relationship curve were analyzed.A new method for matching and forecasting IPR curve was proposed by combining binomial and exponental equations.The forecasted result of a new IPR curve is obviously better than that of the binomial IPR curve. |

| Keywords: | horizontal gas well IPR curve binomial expression exponent equation matching forecasting model |
