摘　　要：随着我国经济的快速发展,能源需求越来越大,传统煤炭资源已经不能满足国家的发展需要。我国煤层气资源丰富,分布广泛,开采成本低,它是一种清洁高效的能源。与石油井和天然气井相比,煤层气井存在井壁坍塌、漏失和卡阻等问题。螺杆钻进法是一种新型钻孔技术,可用于煤层气开采。结合螺杆钻定向钻探技术的原理,以某煤矿一号井为例,分析该技术在煤层气钻井中的应用,然后评价技术应用效果,从而保障煤层气开采安全,更好地开发和利用煤层气资源。With the rapid development of China's economy,the demand for energy is increasing,and traditional coal resources can no longer meet the country's development needs.China has abundant coalbed methane resources,which are widely distributed and have low mining costs,it is a clean and efficient energy source.Compared with oil and natural gas wells,coalbed methane wells have problems such as wellbore collapse,leakage,and blockage.Screw drilling method is a new drilling technique that can be used for coalbed methane extraction.Based on the principle of directional drilling technology using screw drill,taking the No.1 well of a coal mine as an example,the application of this technology is analyzed in coalbed methane drlling,and then the effectiveness of the technology application is evaluated,in order to ensure the safety of coalbed methane mining and better develop and utilize coalbed methane resources.
