大峡谷地热井增水技术措施分析

An Analysis on Measures to Increase Discharge of Grand Canyon Deep Geothermal Well

摘要:

介绍了大峡谷地热井的地质概况、施工工艺；分析了灰岩地质条件下该井出水量较小的原因；提出了增水技术措施并运用于实践，同时对两种技术措施进行了比较分析；对以后类似地质条件下的地热井增水处理提出了建议。

Abstract:

The general geological situation and drilling technology of geothermal well in Grand Canyon were introduced. The causes of small water output from the well which is located in limestone were analyzed. The measurement for increasing water output was provided and applied in practice. Two measurements for increasing water output were compared. The suggestions to increase water output in similar well was made.
