Double-wall drilling tools
Double-wall drilling tools include double-wall gas faucets or gas boxes, double-wall active drill rods, double-wall drill rods, double-wall drill collars, gas-water mixers, positive and negative conversion devices and connection joints. The double-wall drilling tool is suitable for both gas lift reverse circulation drilling and air reverse circulation drilling. The gas lift reverse circulation drilling process has high drilling efficiency, long bit life, good well quality, and drilling in complex formations. The drilling is safe and reliable, and can achieve continuous sampling (core) drilling, saving auxiliary time and reducing labor intensity, etc.; the air reverse circulation drilling process has low air consumption, fast rock cutting back speed, strong ability to carry cuttings, and holes The bottom is clean, the drilling efficiency is high, and the drilling stability is good.
