摘要
云南腾冲火山-地热-构造带科学钻探工程钻遇多期火山喷发地层,地层空、渣、砂、漏等复杂情况严重。介绍了该复杂火山地层大口径空气钻进钻具、设备配套及施工工艺措施,对类似地层工程钻探施工有一定的借鉴意义。
In Tengchong volcano-geothermal-tectonic zone scientific drilling project of Yunnan, while drilling in multi period volcano eruption formation, the complex conditions of hollow, slag, sand and leakage were serious.The paper introduces the large diameter air drilling tools, equipments and technical measures used in this complex volcano formation, which can be taken as reference to the geological engineering drilling construction in similar formations.
