The capillary sealing efficiency of fine-grained sedimentary rocks has been investigated by gas (CO2, N2) breakthrough experiments and CO2 diffusion experiments. Experiments were performed on initially fully water-saturated samples. Absolute (single phase) permeability coefficients (kabs), determined by steady-state flow tests, ranged between 6 x 10 -22 and
5.5 x 10- 19 m 2. Maximum effective permeabilities to the gas phase (kef~), measured after gas breakthrough, ranged from 1 x 10 -23 up to 1.1 × 10 ~8 m 2. Capillary displacement pressures (Pd) ranged from 0.06 to 6.7 MPa. However, for individual claystone samples, gas breakthrough with subsequent pressure-driven volume flow (Darcy flow) was not observed even at much higher differential pressures (15 MPa). In these instances, molecular diffusion is the dominating transport process. It was shown that for nominal permeability coefficients below 10 -24 m 2, a distinction between pressure-driven volume flow and diffusion processes i

毛细管密封的效率，细粒沉积岩已调查的气体（二氧化碳，氮气）突破实验和CO2的扩散实验。实验演出就初步充分饱水的样本。绝对的（单相）渗透系数（ kabs ） ，确定稳定状态流量测试，介乎6 × 10 -22和
5.5 × 10 -1 9米2 。最大有效渗透率，以气相（经营者总协会〜 ） ，后测气体的突破，不等，从1 × 10 -23到1.1 × 10 〜 8米2 。毛细管位移压力（ PD ）的范围从0.06至6.7兆帕斯卡。不过，对于个别粘土样品，气体的突破与随后的压力驱动流量（达西流）中并未观察到，即使在高得多的压差（ 15兆帕斯卡） 。在这些情况下，分子扩散是主导运输过程中。结果表明，标称渗透系数低于10 -24米2 ，区分压力驱动的流量和扩散过程，是不再可能。反复实验，扩散与CO2对同一样品堵塞产生不同的有效扩散系数不等，从10月9日至10 -i 1平方米/秒。这种变化所采取的是作为一个显示复杂的矿物基质的相互作用影响的分子输运性质。
