| 摘 要： | 本文介绍了苏20新井下粗上细结构及成井工艺,其中上部套管内径为146mm,下部套管内径为180mm。对其监测效能进行了分析,并从日潮差、峰谷出现时间、M_2波潮汐因子等角度比较不同井孔结构的响应能力。同时,对地震系统今后建井给出了借鉴性的建议,即按下粗上细新结构、新工艺施工成井,提高地震观测井对地壳应力应变的响应能力。

| Abstract: | This paper introduces the structure and completion method of the new Su20 well. The inner diameter of the upper casing is 146mm,and the inner diameter of the lower casing is 180mm. We analyze the monitoring efficiency,and compare the response ability of different well structures from the way of diurnal tide difference,peak and valley time,M2 wave tide factor and so on. At the same time,some suggestions for future well construction of seismic system are given,that is,to construct wells according to new structures and techniques,so as to improve the response ability of seismic observation wells to crustal stress and strain. |
