| 摘 要： | 相对渗透率是制定油气田开发方案的重要基础资料。通常用非稳态流方法测定和用JBN方法计算它,但未考虑非达西流及毛管力的影响,故只适合于中高渗透岩石达西渗流的情形,且要求非稳态相对渗透率实验驱替速度较高。针对水湿和油湿岩心两种情形,分别导出了同时考虑启动压力梯度、毛管力及重力的相对渗透率公式,不受实验驱替速度较高的限制,解决了低渗透岩石非稳态相对渗透率的实验测定和计算方法问题。 |
| 关 键 词： | 低渗透储集层 非达西流 相对渗透率 不稳定流动 |

| Abstract: | Relative permeability of reservoir is very important for making a development program in an oilfield.It is often tested by an unsteady state flow experiment and calculated by JBN method,which is only fit for Darcy flow through medium-high permeability with high velocity of displacement because of taking neither non-Darcy flow nor capillary attraction into account.Formulas of calculating relative per-meability with starting pressure gradient,capillary attraction and gravity are derived respectively according to water wet core and oil wet core.The formulas can not be restricted by high experimental displacement velocity.This method can be used to deal with lab determination and calculated method for unsteady state relative permeability of low permeability reservoir. |
| Keywords: | low permeability reservoir non-Darcy flow relative permeability unsteady state flow |
