| 摘 要： | 目前大口径钻井施工中常用的泥浆正循环钻进存在着泥浆流速慢、携渣能力差、重复破碎严重、钻井效率低、钻头磨损快、能源消耗大、钻井事故发生率高等问题，气举反循环钻进工艺可有效解决上述问题。风管式气举反循环钻井工艺简单易实现，能有效减少重复破碎，钻进效率高，能源消耗少，钻头寿命长，成井质量好，对涌水和漏失均有很好的抑制作用。介绍了风管式气举反循环钻井工艺原理、专用钻具及其现场使用情况。

| Abstract: | The common used positive circulation drilling for present large diameter well drilling construction has the disad-vantages of low mud flow velocity, poor particle carrying ability, serious breaking repetition, low drilling efficiency, severe drill bit wearing, high energy consumption and high accident rate, which can be effectively improved by air-lift reverse cir-culation drilling technology.The ventilation pipe air-lift reverse circulation drilling technology is simple and easy to apply;it can effectively reduce the breaking repetition with high drilling efficiency, less energy consumption, long bit service life, good well quality and strong inhibition of water gushing and leakage.The paper introduces the ventilation pipe air-lift re-verse circulation drilling technology about its principle, the special drilling tools and the field application. |
