摘要
以燃油发动机驱动的山地物探钻机在钻井时噪声大,尾气排放严重,钻井效率低,拆装、搬运不便。为解决上述问题,以电能驱动代替燃油机驱动,提出了山地物探电动钻机模块化设计方案。基于模糊综合评价法,开展了电动钻机驱动电机和传动方式的定量评价,确定其驱动电机为永磁同步电机,传动方式为链轮链条传动,同时通过对比优选出电动钻机的减速器、支撑部件和导向部件分别为涡轮蜗杆减速器、π形底盘和单桅杆。在此基础上,采用有限单元分析方法进行了电动钻机的安全性分析,结果表明:钻机的最大应力出现在π形底盘连接桅杆的直角处,其值小于钻机材料的许用应力,钻机的结构安全,且电机电路安全可靠。钻井实验结果表明:自主设计的山地物探电动钻机较现有山地物探钻机质量减小了57%,钻井作业时噪声低,无尾气排放,可提供的最大提升力和扭矩分别超过设计标准的71%与6.25%,表明其整体性能符合要求。研究结果为绿色高效的油气勘探装备的研发提供了参考。
The mountain geophysical drilling rig driven by fuel engine has loud noise,serious exhaust emission,low drilling efficiency and inconvenient disassembling and handling.In order to solve the above problems,the modular design scheme of mountain geophysical electric drilling rig was put forward by using electric energy drive instead of fuel engine drive.Based on the fuzzy comprehensive evaluation method,the quantitative evaluation of the driving motor and transmission mode of the electric drilling rig was carried out,so it was determined that the driving motor was permanent magnet synchronous motor and the transmission mode was sprocket chain transmission.At the same time,through comparison,turbo worm reducer,π-shaped chassis and single mast were respectively selected as reducer,support parts and guide parts of the electric drilling rig.On this basis,the safety analysis of electric drilling rig was carried out using finite element analysis.The results showed that the maximum stress of the drilling rig occured at the right angle of theπ-shaped chassis connecting the mast,which was less than the allowable stress of the drilling rig material.It also indicated that the structure of the drilling rig was safe,and motor circuit was safe and reliable.The drilling test results showed that the quality of the independently designed mountain geophysical electric drilling rig was reduced by 57%compared with the existing mountain geophysical drilling rig.The drilling operation had low noise and no tail gas emission.The maximum lifting force and torque provided exceeded 71%and 6.25%of the design standard respectively,indicating that its overall performance met the requirements.The research results provide a reference forthe research and development of green and efficient oil and gas exploration equipment.
