| 摘 要： | 通过室内实验，研究分析了特低渗透储层岩样启动压力梯度与渗透率的关系，利用建立的恒压法油水测定公式测定了油水相对渗透率曲线，描述了特低渗透储层样品的不同压力梯度对渗流特征的影响。这将为特低渗透储层开发提供理论实验依据，对合理开发特低渗透油田有着十分重要的意义。

| Abstract: | This paper analyzes the relation between starting pressure gradient and permeability of ultra-low permeable reservoirs through lab experiment.It obtains a curve of oil and water relative permeability using measurement formula with constant pressure method,and describes the effect of different pressure gradient of the samples of ultra-low permeable reservoirs on flow characteristics.This provides theoretical and experimental evidence for the development of ultra-low permeable reservoirs. |

| Keywords: | low permeable starting pressure non-stable phase flow pressure gradient |
