新疆温泉县AKT1-1地热孔钻探施工技术

Drilling Technology for AKT1-1 Geothermal Well in Wenquan County of Xinjiang

摘要:

针对新疆温泉县地热钻孔AKT1-1孔施工地层构造复杂破碎，岩层裂隙较多及钻孔涌水较大，钻探施工难度较大等问题，从钻孔结构设计、钻探设备选择、钻具级配选型、钻探工艺新技术以及适合该孔的冲洗液配制等几方面进行了总结，提出了相应的钻探工艺技术和应对措施，为后续在该地区进行深部地热钻探施工积累了经验。

Abstract:

According to the difficult conditions of complex formations, much bed crack and serious water inflow in the construction of AKT1-1 geothermal drilling hole in Wenquan County of Xinjiang, the borehole structure design, drilling equipment selection, drilling tool gradation selection, new drilling process and flushing fluid preparation are summarized in this paper and corresponding drilling technologies and countermeasures are put forward to accumulate the construction experience for deep geothermal drilling in this region.
