摘要:

为了优化半主动式补偿绞车的结构、验证该系统的节能及补偿效果,对万米钻井补偿绞车的功率及能耗进行了计算与数值仿真。结果表明:主动式补偿绞车主要克服钻柱负载与传动效率损失;半主动式补偿绞车主要克服传动效率损失、传动系统惯性与被动液压马达扭矩波动。综合考虑能耗、钢丝绳寿命、强度等因素,优化了半主动式补偿绞车的电-液驱动方案与关键结构参数,该系统相对于主动式补偿绞车的节能效果明显。研制了一套载荷2.3 t的补偿绞车原理样机,实验结果表明:绞车补偿的控制效果良好,峰值功率、能耗的变化规律与理论分析基本一致;随补偿幅值的增大,半主动补偿相对于主动补偿节能46.5 % ~26.7 % ;补偿载荷越大、传动惯性越小、传动效率越高,节能效果越明显。

Abstract:

In order to optimize the structure of semi-active compensation winch, as well as verify the energy saving and compensation effect of this system, calculation and numerical simulation were carried out on the power and energy consumption of myriameter drilling compensation winch. The results indicate that the active compensation winch mainly overcome drill string load and the loss of transmission efficiency; the semi-active compensation winch mainly overcome the loss of transmission efficiency, the inertia of transmission system and torque fluctuation of passive hydraulic motor. Based on comprehensive consideration on energy consumption, the service life and strength of rope and other factors, the electro-hydraulic driving scheme and some structural parameters of semi-active compensation winch were optimized, and this system has more significant energy-saving effect compared with active compensation winch. Meanwhile, the principle prototype of compensation winch with 2.3 t load was developed, and the experimental results indicate that the compensation winch shows good control effects, and the variation laws of peak power and energy consumption are basically consistent with theoretical analysis. With the increase of compensation amplitude, the semi-active compensation winch saved energy by 46.5 % -26.7 % over the active compensation winch. The larger the compensation load is, the smaller the inertia of transmission system will be, the higher the transmission efficiency will be, and the more significant the energy saving effect will be.
