| Abstract: | Truck-mounted rig can meet a variety of drilling construction process, mainly used for ground CBM extraction well construction. It has the advantage of high efficiency, strong treatment ability, high mobility and easy-to-use operation etc. Drilling test was completed in Jincheng, Shanxi Province to verify the features of truck-mounted rig, which completed a horizontal directional CBM extraction well with depth of 1 675.39 m and diameter of 171.50 mm.Many drilling technologies such as DTH hammer, directional drilling, mud circulation were adopted and drill process adaptability was verified. The maximum drilling speed was 32 m/h with DTH and the maximum drilling speed is 11.2 m/h with mud circulation. A variety of electro-hydraulic linkage protection function was set, to avoid damage by incorrect operation. There were no failures in the trial and an accident was successfully treated. The rig provided a practical equipment for the construction of ground coalbed methane extraction wells. |
