The relation curves of water phasepermeability of reservoir cores and back-pressure were obtained.
得到了裂缝性低渗透储层岩心水相渗透率随回压的变化曲线。

The measurement results showed that the invasion of the filtrates of oil-base mud and water-base mud has a considerable effect on oil phasepermeability.
测定结果表明，试验所用的油基和水基泥浆滤液的侵入均对油相渗透率造成相当严重的损害。

So, after reservoir watering out as edge water and bottom water enters, the gas phasepermeability will decrease greatly, and strong water lock effect will happen.
