摘　　要：高压水射流技术是近几十年来发展起来的一项油气采掘增产技术,该技术在煤层气开发增产中具有诸多优势,但由于还并未形成一套完善的技术理论体系,该技术没有得到大面积推广。通过收集水射流技术相关资料,介绍了目前高压水射流破煤机理、喷嘴几何参数、磨料水射流、辅助破煤的研究进展,并对现有研究的不足以及今后的发展趋势进行了阐述。High pressure water jet is a technology which is used in oil and gas extraction and obtained high developed in recent decades. This technique has many advantages in the development of coal bed gas, but due to the lack of a complete set of technical theoreti- cal system,the technology has not spread widely. The author of is paper collected water jet technology- related data. The installment looked at a few of the technical issues that remain, such as the mechanism of high pressure water jet breaking coal, nozzle geometry, abrasive water jet and auxiliary broken coal. The shortcomings of the existing research and the future development trend were also discussed.
