摘要
本文根据现有的压汞测试样品，利用多元回归分析，建立了陕甘宁盆地中部气田奥陶系同层段的不同进汞饱和度时的孔喉大小与孔隙度和渗透率间的经验公式．这种方法有可能利用常规岩心分析数据推测样品的毛管压力曲线和孔喉大小及分布．
In this paper, based on the present mercury-injection test samples, we establish, by using the pluralistic regression analysis method, the experimental formulas that express the relationship of pore throat size with porosity and permeability at different mercury saturation degrees of different Ordovician reservoir rocks of the central gas field in Shanganning Basin.This method is likely to be used to predict the capollary pressure curves and the size and distribution of pore throat of the samples with the conventional core analysis data.
