摘　　要：传统的煤层气开采方式主要以水力压裂技术为主,但水力压裂工艺存在很多缺陷,近年来,一种新的氮气压裂工艺因其对地层污染小被广泛应用。设计了一种小型氮气压裂工具,经过初步试验,压裂效果明显,但结构设计还存在一些不足,在此基础上对存在的问题进行了改进,达到了降低生产成本和提高压裂效率的目的。The traditional coal-bed methane exploitation method is mainly hydraulic fracturing technology,but hydraulic fracturing technology has many defects.In recent years,nitrogen fracturing technology,as a new fracturing technology,has been more and more widely used because of its low pollution to the formation.In this paper,a small nitrogen fracturing tool is designed.After preliminary tests,the fracturing effect is obvious.However,there are still some shortcomings in the structure design.After the improvement of the existing problems,the purpose of reducing the production cost and improving the fracturing efficiency is achieved.
