  • 摘要

    为解决车载钻机以往主要依赖进口,使用和维护成本高的问题,亟需研制高性价比且适宜于煤层气钻孔施工的国产车载钻机。在分析地面煤层气开发方式的基础上,总结出钻机应具备2 000 m深的钻进能力,在直井施工时应通过提高工艺适应性来提高钻进效率,定向井应满足孔底钻具角度的精确控制。在此基础上研发了ZMK5530TZJ100型车载钻机,将柴油机动力系统、电液控制系统和钻进系统等集成于车辆底盘之上,结构紧凑;设计了主轴制动功能,实现孔底钻具角度的精确控制;采用伸缩式桅杆结构的给进机构,结构紧凑,行程长;设计了具有多种电液联动保护功能,系统冷却采用恒温闭式控制。ZMK5530TZJ100型车载钻机在晋城寺河矿进行工业性试验结果表明,最大钻孔深度1 675 m,钻机具有较好的工艺适应性和可靠性。

  • Abstract
    In order to solve the high application and maintenance cost problems of the truck-mounted drilling rig mainly imported previously, a domestic truck-moun ted dilling rig with a high price performance ratio and suitable for the coalbed methane borehole drilling was urgently researched and developed. Based on the analysis on the surface ground coalbed methane development mode, the paper had a conclusion that the drilling rig should have a drilling capacity with a depth of 2 000 m. Duri ng the construction of the vertical well, the drilling efficiency should be improved with the suitability of the technique and the directional well should meet the accurate C ontrol of the drilling tools angle at the bottom of the drilling hole. Based on the circumstances, a ZMK5530TZJ10 type truck-mounted drilling rig was researched and dev eloped. The diesel power system, electro-hydraulic control system, drilling system and others were integrated on the truck chassis and the structure was compact. A ma in shaft braking performance was designed and an accurate control on the angle of the drilling tools at the bottom hole was realized. The feeding mechanism with a tele scopic guyed mast structure would have a compact structure and a long stroke. Many electro-hydraulic linkage protection functions were designed and a thermostatic cl osed control was applied to the system cooling. An industrial test was conducted on the ZMK5530TZJ100 truck-mounted drilling rig in Jincheng Sihe Mine and the result s showed that a max drilling depth was 1 675 m and the technical suitability and reliability of drilling rig were better.
