中文摘要:在河南周口市淮阳县地热井施工中，发生了粘性土粘附卡钻、砂桥卡钻等事故，首先采用提拔、碱泡、爆破等措施进行处理，仍有较长钻具遗留在孔内，然后采用套铣方法进行处理，成功将遗留钻具从孔内提出，完成了孔内事故的处理。总结了该孔处理经验，可供类似工程参考借鉴。

Instance of Casing Milling Process for the Wall-sticking in Geothermal Well
Abstract:Wall-sticking and sand bridging happened in the geothermal well drilling construction in Huaiyang of Henan. After pulling, natron infiltrating and blasting, there were still several pieces of drilling tool remained; and finally the remained tools were taken out by casing milling. This experience can be reference to the similar engineering.
