摘　　要：空气钻井是一种利用空气作为循环介质的新型钻井技术,其循环系统的压力分布、钻井机械的选择、钻井参数的配置都和传统的钻井技术有很大的差别,本文主要研究的是在空气钻井中,岩屑的受力分析及作用机理,然后利用CFD软件模拟在不用入口压力下,能实现环空钻井的最小注气量。Air drilling is a drilling technology which uses air as the recirculated medium.There are many differences in the pressure distribution of circulatory system,the choice of drilling machinery and the configuration of drilling parameters between air drilling and other conventional drilling technologies.In this paper,we mainly focused on the force analysis and mechanism of rock chip in air drilling,and then did a simulation experiment to achieve the minimum injection gas of annular drilling with the CFD software under the condition of without entrance pressure.

关 键 词：空气钻井 受力分析 最小注气量
