【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 problem that the onboard drilling rig used to rely mainly on imports and the cost of use and maintenance was high, it is urgent to develop a high performance-to-price drilling rig which is suitable for drilling and construction of coalbed methane. Based on the analysis of the development mode of surface coalbed methane, It is concluded that drilling rig should have the drilling ability of 2 000m depth, the drilling efficiency should be improved by improving the technological adaptability in the vertical well construction, and the directional well should satisfy the accurate control of the angle of the hole bottom drilling tool. On this basis, the ZMK5530TZJ100 truck drilling rig has been developed. The diesel engine power system, electro-hydraulic control system and drilling system are integrated on the chassis of the vehicle, the structure is compact, the main shaft braking function is designed to realize the accurate control of the angle of the hole bottom drilling tool, and the feeding mechanism of the telescopic mast structure is adopted. The structure is compact, the stroke is long, the system cooling adopts the constant temperature closed control. ZMK5530TZJ100 drilling rig is used in the industrial test of Jincheng Sihe Mine. The maximum drilling depth is 1 675 m, and the drilling rig has good process adaptability and reliability.
