摘要

车载钻机可满足多种钻进工艺施工,具有钻进效率高、事故处理能力强、机动灵活和操作简单等优点,主要用于地面煤层气抽采井的施工。为检验ZMK5530TZJ100型车载钻机的性能,在山西晋城进行了实钻验证,完成了一口终孔直径171.50 mm、井深1 675.39 m的水平定向煤层气抽采井。施工过程中,采用了空气潜孔锤、泥浆正循环、孔底马达定向钻进等不同的工艺,检验了钻机对工艺的适应性;潜孔锤最高钻速达32 m/h,泥浆循环最高钻速达11.2 m/h,钻进速度快;设置的多种电液联动保护功能,避免了因误操作造成的机构损坏;试验中未发生任何机械故障并成功处理一次卡钻事故,该钻机为地面煤层气抽采井施工提供了一款实用装备。
Abstract

Truck-mounted rig can meet a variety of drilling construction process, mainly used for ground CBM ex- traction 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 func- tion was set, to avoid damage by incorrect operation. There were no failures in the trial and an accident was suc- cessfully treated. The rig provided a practical equipment for the construction of ground coalbed methane extraction wells.
