南宁市九曲湾深层地热井成井工艺

Well Completion Technology for Jiuquwan Deep Geothermal Well in of Nanning City

摘要:

南宁市九曲湾地热井是广西首眼深层地热井,也是广西第一口以深部下第三系细砂岩为主要取水段的地热探采结合井,该井的实施填补了广西在无地热异常显示尤其是热储层分布不连续的新生代沉积盆地型地热资源开发的空白.着重介绍了该井的施工成井工艺.

Abstract:

Jiuquwan geothermal well was the first synchronous exploring and producing well, which took the deep tertiary fine sandstone as the main water intake region. The completion of the well filled the blank of geothermal resource exploitation in the Cenozoic Sedimentary basin with un-continuous reservoir. The well completion technology for the deep geothermal well was mainly introduced in this paper.
