| 摘 要： | 苏里格砂岩气藏的主力储气层为二叠系石盒子组盒8段，具有低孔、低渗、低压、强水锁等特性．本文针对苏里格盒8段储层特征，对储层岩心开展了室内试验研究，并就外来液体侵入储气层而造成伤害的微观机理进行了分析．研究表明，外来液体的侵入将对储层造成严重的伤害．因此，应进一步加大外来流体与储层的配伍性，同时减少外来流体对储层的浸泡时间。 |

| Abstract: | The eighth member of Shihezhi formation of Permian is a major gas-bearing layer in Sulige. This gas reservoir of sandstone has characteristics of low porosity, low permeability, low pressure and strong water blocking, etc. Aiming at the characters of the gas reservoir and based on tests of cores of reservoir, the micro mechanism of damage to the reservoir caused by incursion of extraneous fluids has been analyzed. The results show that incursion of extraneous fluids may result in a severe damage to the reservoir. Therefore, the compatibility of extraneous fluids and reservoir should be improved. In the meanwhile, the marinating time of extraneous fluids to the reservoir should be reduced as much as possible. |
