Abstract:

Through the shaft reconstruction of the well under the condition of artifical automatic flow,we managed to keep the continuous measurement of concentration of chemical contents and water level by adopting shaft observation method.After observation for more than a year,it has been revealed that the crisis of halt of measurement of the well was removed.Moreover, it provides a new approach for technological reconstruction of high temperature artesian well.

Key words: Huai-4 well, well-hole reconstruction, subsurface fluid, comprehensive observation

摘要：

河北省怀4地下流体综合观测井自2007年起水流不断减少,直至濒临断流,我们将其改造成竖井以保证持续进行地下水化学量浓度和水位综合观测。改造后一年多的实践表明,改造是较为成功的,不仅解决了该井停测的危机,还为其他高温热水自流井未来改造开拓了新的技术途径。
