| 摘 要： | 差干井在2004年12月26日印尼MS8.7地震时发生强烈井喷,喷柱高达60m。调查与分析结果表明,井喷是在特定的井区水文地质条件下,富含CO2气体的观测含水层地下水受到地震波的扰动,一方面使大量吸附气被释放,另一方面使游离气泡被打碎,导致地下水被"汽"化,从而使含水层孔隙压力剧增引起的 |

| Abstract: | Violent blowouts occurred in Chagan Well when the MS 8.7 Sumatra earthquake happened on Dec.26,2004,with the eruptive fountain up to 60m high.The result of investigation and analysis of Chagan well indicates that blowout occurred in the condition of special hydrogeology.The water of monitoring layer was rich of CO2.When the aquifer of monitoring was disturbed by the earthquake wave,a large number of absorbed gases were released.On the other hand,free bubble was broken by the earthquake wave and the groundwa... |
