摘要： 对克拉玛依油田二中区三采试验区克下组($T_2^1$k)油藏的41条实测毛细管压力曲线 及渗透率、孔隙度分析数据，采用数据拟合方法，建立了在不同压力下的渗透率与孔隙度比值和汞饱和度的关系图版。毛细管压力的拟合曲线与实测的毛细管压力曲线有较好的一致性。

Abstract: On the basis of 41 measured capillary pressure curves and analysis data of permeability and porosity in Lower Karamay formation reservoir (T2k) in tertiary recovery pilot area in middle District No.2 in Karamay oilfield, this paper established the plot of permeability and porosity, mercury saturation under different pressures by adopting data-matching method.Results show better agreement between predicted and measured capillary pressure curves.
