摘　　要：高能气体压裂的设计对该项技术的深入研究十分重要。本文对高能气体压裂的设计方法作了初步探讨。设计内容包括该技术的适用范围、压力过程设计、火药燃烧分析、并筒泄气分析、裂缝扩展分析、增产效果预测等。由于高能气体压裂的工作介质是具有可压缩性的火药生气,因此,以上各项分析相互关联。本文还给出了高能气体压裂设计计算的流程。The design of high energy gas fracturing(HEGF)is crucial to the further development of the technique. This article presents a preliminary approach to the design method of HEGF. The content of the design comprises applicable circumstances, design of pressure history, analysis of propellant burning, analysis of gas drainage from wellbore, analysis of fracture propagation, prediction of stimulating effect, etc. As the working medium is compressible gas out of burning propelllant, the above analyses are interrelated. The process of HEGF design calculation is also given.
