地下气体运移机理及清水流量井水变蓝现象的解释

Transport Mechanism of Underground Gas and Explain to Phenomenon of Blue-water at Qingshui well in Gansu

摘要:

甘肃省清水县07#流量井先后多次出现过水变蓝的现象。该井位于地热异常区,地下深部流体活动异常。本文通过清水流量井地质环境调查,从物理化学两个方面分析了地下气体的成因、储存及运移机理,并利用地下流体"气-液二相对流模式"快速运移机理,结合异常期间水质分析的结果,探讨了清水流量井水变蓝现象的原因,对今后地震地下流体前兆分析提供重要的理论依据。

Abstract:

There were many times the water in 7# well in Qingshui county of Gansu province,changed to blue colour.The well is located in the anomalous hot area,where deep fluid have abnormal activities.In this paper,the geological environment of the well is surveyed,the causes,storage and transport mechanism of underground gas are analyzed using physical and chemical methods.Meanwhile the causes of blue water phenomenon is explained by ＂The bubble migration mechanism＂,it would provide an important theoretical basis for analysing the earthquake precursor in future.
