摘要： 在空气雾化钻井中,井眼环空携岩流动是一种典型的气、液、固多相流动,其机理和规律十分复杂。在空气雾化钻井实践中,经常出现钻井生产无法顺利进行的情况,轻则带屑不好,钻井效率低;重则井眼段塞、井壁垮塌、引发卡钻、井下爆炸等事故。显然,井眼环空携岩问题是空气雾化钻井必须解决的基础理论问题。根据满足工程精度的原则,利用空气雾化钻井环空流动试验研究对一维高载荷流动模型进行了验证,研究结果对空气雾化钻井生产实践有重要的指导作用。

Abstract: In air and mist drilling, annular carries are the typical of gas, liquid and solid multiphase flow, and its mechanism and principles are very complicated. In air and mist drilling practice, the process of drilling does not carry out very well. Generally, the annular carries are not good, and low drilling efficiency, even the borehole held block and its wall collapse, resulting in blocking a drilling tool and causing the explosion under well etc. Obviously, annular carries is the basic theory question that must be solved in air and mist drilling. On the basis of the principles satisfied the engineering precision, experimental researchof annular carries in air-mist drilling was used to verify the one dimension high-load flow model, and the results have an important guidance meaning in air-mist drilling practice.
Key words: air- mist drilling, annular carries, multiphase flow, testing
