摘　　要：山西霍州煤电集团鑫博煤业霍3号水源井工程,地层复杂漏失严重,开始采用顶漏钻进,工程进度难以保证,施工成本高,后改用空气泡沫钻进,解决了漏失地层钻进难题,钻进效率高,钻探成本低。介绍了该水源井空气泡沫钻进施工工艺,并对钻探效果及成本进行了对比分析。The leakage is serious in the complex formation of a water source project in Huozhou coal-electricity group of Shanxi. Drilling against circulation loss was adopted at first with high construction cost, but it was still difficuh to guarantee the project progress. The drilling difficuhies in leakage formation were solved by are-foam drilling with high drilling efficien- cy and low drilling cost. The paper introduced the technology of air-foam drilling in the water source well construction and analyzed the drilling effect and the drilling cost with comparison.
