河北平原区地震监测井成井技术
|
摘要
井下地震监测可减少地面噪声干扰、提高地震监测精度。介绍了河北平原区地震监测井的设计以及成井、下管、固井等的关键工艺方法,在工程施工中采用合理的成井工艺、封底下管、管外固井等技术,满足了监测井的特殊要求。
Seism monitoring under ground has higher accuracy with less noise jamming from the ground surface.The paper introduced the design of seism monitoring well in Hebei plain and key technology of well completion,pipe laying and well cementing.Proper well completion technology,pipe laying with bottom sealing and well cementing outside the pipe were used for the special demand of monitoring well.
