Through the analysis of the reservoir seepage capacity and high-pressure mercury intrusion porosimetry, the minimum flow pore throat radius and the lower limit of petrophysical properties have been studied. The three seepage state modes include theoretical seepage, production seepage. and filling seepage. The results show that the minimum flow pore throat radius and the lower limit of petrophysical properties of theoretical seepage are the lowest in the three seepage states. The minimum flow pore throat radius and the lower limit of petrophysical properties of theoretical seepage can be used to distinguish between the reservoir and non-reservoir conditions. They can be used to distinguish between the utilized reservoir and non-utilized reservoir under production seepage and to distinguish between oil-bearing and non-oil-bearing reservoirs under filling seepage. Therefore, the reference parameters can be used for the identification of reservoirs and oil-bearing reservoirs and the study of reserves utilization degree.

通过对储层渗流能力和高压压汞法的分析，研究了最小流孔喉径和岩石物性下限。三种渗流状态模式包括理论渗流，生产渗流。并填充渗流。结果表明，在三种渗流状态下，最小流量孔喉半径和理论渗流的岩石物理特性下限最低。最小流量孔喉半径和理论渗流的岩石物理特性下限可用于区分储层和非储层条件。它们可用于区分生产渗漏下的已利用储层和未利用储层，以及区分充填渗流下的含油储层和非含油储层。因此，该参考参数可用于油藏，含油油藏的识别和储量利用程度的研究。
