| 摘 要： | 气举反循环钻进技术是水文井钻进施工、水井修复以及大直径井施工中的一种有效手段，通过对故障水井的探查，查明了故障水井产生垮塌、掉块、涌砂淤塞的部位与特征，针对性地制定了修井方案。修井效果与常规的正循环钻进技术透扫＋捞砂管捞砂方法相比．效率与质量都有较大的提高。

| Abstract: | The air-lift inverse circulation technology is an effective means in water well drilling, repairing and large diameter well construction. Through ascertainment of defective water well, found out positions and characteristics of collapse, caving-in, sand gushing and silting up, put forward pertinent repairing schemes. Comparing with conventional normal circulation technology penetrating and clearing ＋ sand-bailing by bailing tube, the method has obvious improvement on effect and quality. |
