备注

介绍了潜水泵变频稳流抽水观测新技术系统的构成和工作原理,并结合汤参[1]井的实际应用情况进行分析,发现这一新技术的引进不仅恢复了原有的各测项观测,而且消除了邻近热水开采井对各测项动态的干扰,使井水位动态对地壳应力应变的响应能力得到显著提升,实现了地下流体物理化学多测项的综合观测。这一新技术不仅适用于已经断流或面临断流的地震观测井中,也适用于把静水位观测井改造成人工稳流抽水观测条件下的地下流体物理化学综合观测井,从而提高地震地下流体观测台网的地震监测能力。

The construction and working principle of the new technique pumping observation system of submersible pump frequency conversation steady flow is introduced. Combing with the actual application condition of the new system on Tangcan-1 Well,we found that the introduction of the new technique not only retrieved the observation of each item,but also eliminated dynamic interference of the adjacent hot water mining well on each item,and obviously improved the response ability of well water level to crustal stress and strain to realize subsurface fluid comprehensive observation of physical and chemical multi-items. The new technique applies to seismic observation wells of zero flow and facing zero flow,and transformation of hydrostatic level observation well to underground fluid physical and chemical comprehensive observation well in the observational condition of artificial steady flow water dumping,in order to improve the seismic monitoring ability of underground fluid observation network.
