高速非Darcy 流导致附加的压力损失，降低流体的流动效率，对油气生产十分不利。到底是低渗 透储层容易产生高速非Darcy 流，还是高渗透储层容易产生，一直没有明确的认识。前人研究结果显示， 低渗透储层容易产生高速非Darcy 流，但低渗透储层的流体流动极其困难，生产过程很难产生高的渗流 速度。该文根据流体力学的相关知识，研究了高速非Darcy 流产生的条件和高速非Darcy 流的影响因素， 并认为：高渗透储层容易产生高速非Darcy 流，而低渗透储层不容易产生，低渗透储层的开发过程可忽略 高速非Darcy 流的影响。

High rate non-Darcy flow increases additional pressure drop and decreases flow efficiency in reservoirs, which is unfavorable to petroleum production.Whether high rate non-Darcy flowis easier to occur in low permeability reservoirs or in high permeability reservoirs is a problem unsolved well. Previous experiment results by several authors showthat low permeability reservoirs are more suitable for high rate non-Darcy flowto occur. However flowin low permeability reservoirs is extremely difficult and high rate can not be reached usually. According to mechanics of fluids, conditions of high rate non-Darcy flow and factors causing high rate non-Darcy flow were studied. It is considered that high rate non-Darcy flowis easier to occur in high permeability reservoir than in low permeability reservoir. So the effect of high rate non-Darcy flowcan be neglected in development of low permeability reservoirs.
