煤矿瓦斯抽排立眼套管安设及水泥固井工艺探讨

Discussion on Casing Installation for Methane Drainage Vertical Borehole and Cementing Process in Coalmine

摘要:

在煤矿瓦斯抽排立眼施工的过程中，套管安设及水泥固井是两个关键性的工序，如果出现失误，便可能产生严重的工程事故，甚至可能使整个工程报废。本文通过对坪上煤矿瓦斯抽排立眼工程的套管安设及水泥固井工序的施工，吸取了一些套管安设的事故教训，总结了一些套管安设、水泥固井的经验，有望对今后类似工程的安全施工提供帮助。

Abstract:

In the construction process of methane drainage vertical borehole in coalmine, the casing installation and cementing are very important. By the construction practice of methane drainage vertical borehole and cementing process in Pingshang coalmine, this article presented some lessons from the accident and summed up the experiences of casing installation and cementing for the similar projects in the future.
