声波钻进技术具有速度快、岩心保真好、适用地层广等优点，广泛应用于工程勘察、环境调查、浅源地热、基础工程、矿山治理等领域。为了提高声波钻进施工质量和过程控制，美国材料与实验协会于2004年制定了第一部声波钻进规程D6914—04，后经多次修订完善，形成最新声波钻进规程D6914/D6914M—16。本文根据该版规程内容，从技术原理、钻进设备、成孔工艺等方面展开了阐述。当振动器与钻柱谐振频率重叠时，声波钻头受到的能量达到峰值。钻机和取心钻具是声波钻进的核心设备。成孔工艺主要以双管高频振动、低速回转为主，实现多种目的层的原位取心作业。标准相关内容对声波钻进技术在我国的持续推广具有参考意义。
The sonic drilling technology has the advantages of high speed, good core fidelity and wide application horizon. It is widely used in engineering survey, environmental investigation, shallow source geothermal, basic engineering, mine management and other fields. In order to improve the construction quality and process control of sonic drilling, the American Society for Materials and Experiments developed the first sonic drilling program D6914—04 in 2004. After many revisions and improvements, the latest sonic drilling program D6914/D6914M—16 was formed. According to the content of this edition, this paper expounds from the technical principle, drilling equipment, hole forming process and so on. When the vibrator overlaps the drill string resonance frequency, the energy received by the sonic drill bit peaks. Drilling rigs and core drilling tools are the core equipment for sonic drilling. The hole forming process is mainly based on double-tube high-frequency vibration and low-speed rotation, and realizes in-situ coring operation of various target layers. Standard related content has reference significance for the continuous promotion of sonic drilling technology in China.
