The flow in low-perm reservoirs docs not observe the Darcy's Law.
低渗透油气层由于存在启动压力梯度,渗流规律不符合达西定律,而现今实验室处理相对渗透率曲线的JBN方法是建立在达西定律基础上的,没有考虑启动压力梯度的影响。
Generalized Darcy's law was first derived from the study of fluid flow through a solid-fluid mixture,and the saturated permeability tensor of a preform could be predicted by studying its unit cell under periodic boundary conditions.
首先,采用均匀化理论分析了流体在多孔介质内的流动问题,推导出广义达西定律,证明以施加周期性边界条件的单胞为研究对象,可以预测预成型体的渗透率张量,并以单向纤维织物为例,对该方法进行了验证。
Method\ The multi-dimensionally definite flow and retention characteristics of low-permeability reservoirs is studied by using Darcy's law.

A permeability coefficient formula after cohsideration of initial hydraulic gradient and the formula of initial water head were put forward based on Darcy Law of cohesive soil and the continuity of stream,then errors were estimated through range of permeability coefficient,the maximal deviation and square deviation between back-calculated water head and actual water head.
基于粘性土的达西定律和水流连续性原则,建立了考虑起始水力坡降时粘性土的渗透系数公式和起始水头计算公式,并通过渗透系数的极差、反算水头和实测水头的最大偏差和均方差来评价所提出的公式和规程公式的误差。
First of all,the traditional Darcy law was modified,and the complete effective Darcy law(model) inside the complete and effective seepage field in porous media was derived.
首先,对传统的达西定律形式进行修正,提出了孔隙介质完备有效的达西定律(模型);然后,对该模型中渗透参数的特性进行了讨论和分析,得出了一些有益的结论。
