常规研究方法在低渗储层物性下限确定中有较大局限性，为了准确界定该类储层的物性下限，以压汞实验、水锁实验和核磁共振实验为基础，建立了以最小流动孔喉半径确定该类储层物性下限的方法，即从岩石的微观孔隙特征出发，首先利用实验方法确定含气层段的最小流动孔喉半径，进而根据实测数据建立孔喉半径与孔隙度、渗透率相关关系，从而确定储层的孔隙度和渗透率下限。应用该方法对川南河包场须家河组气藏的低渗储层物性下限进行研究，确定了河包场地区须二、四、六段有效储层孔隙度下限分别为5.5%，5%，3.8%；渗透率下限分别为0.03×10-3，0.11×10-3，0.12×10-3?滋m2。

The lower limit parameters of a reservoir play an important role in the reservoir exploration and development. Conventional methods are greatly limited in determining the lower limits of low porosity and low permeability reservoirs. In this paper, based on the mercury penetration experiment, water-blocking experiment and NMR experiment, the methods of determining the lower limit parameters within the low permeability reservoir are proposed by using the minimum flow pore throat radius. That is, considering low permeability reservoir's microscopic characteristics, the minimum flow pore throat radius of the gas-bearing section is first determined, and then the relationships between porosity, permeability and median radius are established in order to calculate the low limits of porosity and permeability. Using this method, the lower limits of porosity and permeability of the Xujiahe Formation (T3x) gas reservoir in Hebaochang area are determined: the lower limits of porosity in T3x2, T3x4 and T3x6 Formation are 5.5%, 5% and 3.8%, and the lower limits of permeability are 0.03×10-3, 0.11×10-3 and 0.12×10-3?滋m2.
