摘要：研究表明，不仅在高产气井，在某些高产挥发性油藏以及其他储层条件下都有可能产生高速非达西渗流。日前常用的高建非达西渗流判别理论公式与解析公式均以裸眼究井为起点，未考感实际生产中究并方式的影响。因此，在基于二项式的产能方程的基础上，考虑射孔完井对泄流面积的影响，雄乎出射孔条件下的高速非达西产能方程，并结合国外某高产并评价完井方式对其高速非达西效应的影响。结果表明，当孔密超过25孔/m时射孔完并的泄流面积大于对应的裸眼井，高建非达西效应相应减弱。图此在评价实际生产并近井地带的高速非达西效应时，必须考虑究并方式的影响

Abstract: Previous research results show high-speed non-Darcy flow can occur in high-productivity gas wells, high-productivity volatile oil reservoirs and under various other reservoir conditions. Conventional theoretical equations and analytic formulas for high speed non-Darcy flow are based on open-hole completion without considering the impact of actual completion mode in actual produc-tion. The newly developed productivity equation based on binomial expression takes the impact of perforation completion on drainage area into consideration in deriving high-speed non-Darcy productivity equation. Data from one high-productivity well overseas was used to assess the impact of completion on high-speed non-Darcy effect. The research results show perforation completion may gener-ate higher drainage area when the perforation density is over 25 holes/m. Under such circumstance, high-speed non-Darcy effect is less intensive. In conclusion, the impact of completion mode shall be considered during assessment of high-speed non-Darey effect in near-well zone of actual producers

目前评价高速非达西效应的理论模型主要有雷诺数（Re）模型与Forchheimer数（Fo）模型【1-2]。雷诺数判别方法基于对管流流动形态的研究，后被应用到多孔介质渗流流型研究中，是国内应用最早、
应用最为广泛的理论模型，如前苏联的卡佳霍夫公式仍是目前普遍用于判定高速非达西流动的方法。 Forchheimer数由渗流理论推导得到，其中的非达西系数具有明确的物理意义，常用于定量评价非达西
