中文摘要：

很好测试作为精确地获得低渗透的水库的形成参数并且有效地分析 deliverability 的一个有效工具被认出。很好，测试模型必须在低渗透的水库遵循流动的特别特征以便获得合理的井测试解释。目前，在低渗透的水库的 non-Darcy 流动正在吸引许多注意。在这研究，排水量测试在从低渗透的水库拿的典型核心上被进行。二个无尺寸的变量被介绍给分析收集了试验性的数据。无尺寸的分析的结果显示出 non-Darcy 流动是否发生取决于液体和多孔的媒介和压力的性质微分。上述三个参数的联合作为无尺寸的标准系数(两重棉包线) 被说出。当 DCC 的价值比一个批评雷纳兹数字(CRN ) 低时，当两重棉包线比 CRN 高时，流动不能被 Darcys 法律(所谓的 non-Darcy 流动) 很好描述，流动遵守了 Darcys 法律。最后，这份报纸建立在低渗透的水库考虑 Darcy 流动和 non-Darcy 流动的一个短暂数学模型，并且建议方法论解决模型。答案技术，基于 Boltzmann 转变，很好适合解决低渗透的水库的流动模型。基于典型曲线分析，压力和它的衍生物曲线被象 non-Darcy 流动索引和流动特征的如此的参数决定，这被发现。结果能被用于低渗透的水库的测试分析很好。

英文摘要：

Well testing is recognized as an effective means of accurately obtaining the formation parameters of low-permeability reservoirs and effectively analyzing the deliverability.Well test models must comply with the particular characteristics of flow in low-permeability reservoirs in order to obtain reasonable well test interpretation.At present,non-Darcy flow in low-permeability reservoirs is attracting much attention.In this study,displacement tests were conducted on typical cores taken from low-permeability reservoirs.Two dimensionless variables were introduced to analyze the collected experimental data.The results of the dimensionless analysis show whether non-Darcy flow happens or not depends on the properties of fluid and porous media and the pressure differential.The combination of the above three parameters was named as dimensionless criteria coefficient（DCC）.When the value of the DCC was lower than a critical Reynolds number（CRN）,the flow could not be well described by Darcy＇s law（so-called non-Darcy flow）,when the DCC was higher than CRN,the flow obeyed Darcy＇s law.Finally,this paper establishes a transient mathematical model considering Darcy flow and non-Darcy flow in low-permeability reservoirs,and proposes a methodology to solve the model.The solution technique,which is based on the Boltzmann transformation,is well suited for solving the flow model of low-permeability reservoirs.Based on the typical curves analysis,it was found that the pressure and its derivative curves were determined by such parameters as non-Darcy flow index and the flow characteristics.The results can be used for well test analysis of low-permeability reservoirs.
