在分析了国内各油田现有两类修井设备的优点和不足之后，根据目前油田的道路和井场条件，提出了利用现有修井设备改制修井机的方案，并已付诸实施。改制的修井机将通井机。立放运井架车、平板拖车等设备的功能集于一体，不仅充分发挥了油田现有设备的综合效能，且各项性能指标完全满足修井工艺要求。累计1200多小时的使用情况表明，改造机运转良好。用户反映改制的修井机操作简单，维修方便，且作业效率是通井机的2－3倍，价格是修井机的1／3－1／2，投产3－4个月即可收回投资。
After analyzing the advantages and disadvantages of two types of workover equipment in domestic oilfields, according to the current road and well site conditions of oilfields, a plan to revamp workover rigs with existing workover equipment is proposed and put into practice. Converted workover rig will be well machine. Lifting the functions of equipment such as derrick trucks and flatbed trailers, etc., not only gave full play to the comprehensive efficiency of existing equipment in the oilfield, but also fully met the workover requirements of various performance indexes. A total of more than 1200 hours of use shows that the conversion machine is working well. Users reflect the restructuring of the workover rig is simple, easy maintenance, and operating efficiency is 2-3 times the shaft machine, the price is 1 / 3-1 / 2 workover rig, put into operation 3-4 months to recover the investment .
