摘　　要：本文从理论模型、实验过程和测量结果等方面阐述恒速压汞法与常规压汞法的异同。恒速压汞法可区分孔隙和喉道,常规压汞法区不能;恒速压汞法可反映喉道与孔隙的数量分布情况。运用恒速压汞法可获得总体毛管压力曲线、孔隙毛管压力曲线及喉道毛管压力曲线,测试所得到的毛细管压力值及喉道半径值更接近真实情况。This paper profoundly expounded the difference between constant-speed mercury injection and conventional mercury injection technique in the theoretical model,experiment and measurement results.The pore and throat can be dis-tinguished by constant-speed mercury injection technique,but the conventional mercury injection technique is unable to distinguish the pore and throat.The constant-speed mercury injection technique can reflect the distribution of throat and pore.General capillary pressure curve,pore capillary pressure curve and throat capillary pressure cure can be obtained by using Constant-speed mercury injection technique.The obtained capillary pressure and the obtained throat radius is clos-er to the real situation.Constant-speed mercury injection technique is a good method to study rock pore structure.
