摘　　要：绞车作为深井钻机提升系统的主要动力设备,其设计的先进性对钻机整体的性能、效率及成本控制均有着重要意义。目前国内外普遍采用异步变频电动机和齿轮减速箱作为绞车传动装置,该机构存在低速(恒压、恒速钻进)不稳定、结构复杂、维护工作量大、能耗成本高等问题。本文在现有钻机提升动力设计技术的基础上,提出了一种永磁同步电机在深井钻机绞车提升系统中的设计方案及其应用案例。根据永磁同步电机自身特点设计了一种无减速箱的双电机直驱系统,基于矢量闭环控制技术设计了相应的电控系统,在实际施工现场对其典型运行特性进行了测试分析,与同井场、同型号传统电动钻机的能耗对比分析表明,永磁同步电机绞车具有结构更为简单、维护及能耗成本更低的特点。As the main lifting system power equipment of deep well drilling rig,the advanced design of winch is of great significance to the overall performance,efficiency and cost control of drilling rig.At present,the domestic and foreign deep drilling rig generally uses asynchronous variable frequency motor and gear reducer as the winch transmission device,which has low speed(constant pressure,constant speed drilling)instability,complex structure,heavy maintenance workload,high energy consumption cost.Based on the existing lifting power design technology of drilling rig,this paper presents the design and application of a permanent magnet synchronous motor in the lifting system of deep drilling rig.First,a dual motor direct drive system without gearbox was designed according to the characteristics of permanent magnet synchronous motor,and then the corresponding electronic control system was designed based on the vector closed‑loop control technology.Finally,its typical operating characteristics were tested and analyzed on the practice,and the energy consumption was compared by comparing the traditional electric drilling rig of the same model in the same well site and the relevant conclusions were drawn.In contrast,the permanent magnet synchronous motor drawworks has the characteristics of simpler structure,lower maintenance and energy consumption costs.The operating characteristics and energy consumption of the same type of drilling rig are analyzed and compared.
