我国地震地下流体观测台网调整与优化方案探讨

A discussion about the adjustment and optimization of subsurface fluid monitoring network in China

  • 摘要: 本文首先简要介绍了我国地震地下流体观测台网的现状,然后针对其存在的主要问题提出了调整与优化的建议: ① 调整布局,重点加强我国中西部地区(105°E以西)的监测; ② 扩大规模,观测井(泉)数要达到1000个左右; ③ 全面提高观测井质量,淘汰不符合规范要求的观测井(泉),改造不完全符合规范要求的观测井,新建一批完全符合规范的观测井; ④ 优化观测项目的组合,大力发展观测井(泉)水流量观测,强化以H2、 He、 CO2等为主测项的断层带土壤气观测,建立断层带土壤气观测网; ⑤ 优化现有的观测模式,开展平面上的台阵式观测与垂向的多层次立体化观测; ⑥ 完善与提升现有数字化观测技术水平.

     

    Abstract: The current situation of the earthquake subsurface fluid monitoring network in China is briefly introduced. And then, some suggestion on adjustment and optimization of the network are proposed. ① Change the layout of the existing monitoring network so as to focus on the middle-western China, particularly to the west of 105°E. ② Increase the number of monitoring wells or springs up to approximately 1000. ③ Improve the quality of monitoring network, eliminate and transform those wells or springs that do not meet for the standards and requirements at all. ④ Optimize the monitoring items, focus on the monitoring of the wells or springs flows, the soil vapor in the vicinity of faults (main parameters are H2, He, CO2), and construct a soil vapor network. ⑤ Optimize the existing monitoring modes, establish the plane array observation and vertical multi-level three-dimensional observation. ⑥ Improve the existing digital monitoring technology.
