| 摘 要： | 采用数值试井模拟方法，建立压裂水平井数值试井模型，模拟分析压裂水平井在各种产能影响因素下的压力一产量特征及绘制采出程度IPR曲线，采用Vogel处理方法，将采出程度IPR曲线纵坐标转换为产量无因次量，将横坐标转换为压力无因次量，对无因次化压力一产量数据进行统计和回归分析，最终形成具有普遍代表意义的压裂水平井动态IPR产能评价公式，为低渗气藏压裂水平井产能评价提供简便、快速的新方法。

| Abstract: | Using the numerical well test simulation method,a numerical well test model of fractured horizontal wells has been established.Simulation analysis of the pressure-production character of fractured horizontal wells is carried out considering various productivity-influencing factors.Based on the simulation analysis results,the nondimensional IPR recovery percent curve is drawn.By the statistics and regression analysis of the IPR curve,the IPR productivity evaluation formulation of fractured horizontal wells i... |
