| 摘 要： | 为研究特低渗透油藏岩心气、油或水单相流动渗透率的变化，利用朝阳沟油田扶杨油层岩心进行了室内实验，证实了特低渗透岩心单相流体渗流的启动压力和渗透率降低幅度与所用流体性质有关，启动压力增大幅度随气测渗透率减小而增加，渗透率降低幅度随着气测渗透率的降低而增大。

| Abstract: | In order to understand permeability change of single phase flow of gas,oil and water in cores from ultra low permeability reservoir,the cores from Fuyang reservoir of Chaoyanggou oilfield are used to conduct laboratory experiment.It has been verified that the threshold pressure and the degree of permeability decline of single phase flow are related with fluid property.The increasing degree of threshold pressure will increase with the decline of gas logging permeability,and the degree of permeability decline will increase with the decline of gas logging permeability. |

| Keywords: | ultra low permeability reservoir single phase flow non-Darcy flow gas logging permeability experiment |
