ZJ40/2250DBT交流变频电动拖挂钻机的研制

为了实现钻机的自动化、智能化操作,满足中深井、复杂井以及欠平衡钻井等复杂工况的要求,研制了ZJ40/2250DBT交流变频电动拖挂钻机。该钻机主要由绞车、液压盘式刹车系统、变频电动机、减速器、自动送钻系统、转盘及传动装置、井架、钻台、半拖车、控制系统等部分组成。试验及应用情况表明,该钻机最大钩载达到设计要求,可满足114mm钻杆4000m的钻井能力;钻机结构简单、安装方便、搬运快捷、稳定可靠,能适应恶劣环境下的钻井要求。

Development of ZJ40/2250DBT AC variable frequency electric trailer-mounted drill rig

In order to fulfill the automatization and intelligentization,meet the complex working situation requirement,such as intermediate deep well,complex well and under-balance drilling,RG Petro-Machinery Company develops ZJ40/2250DBT AC variable frequency electric trailer-mounted drilling rig by absorbing domestic and overseas advanced technology and experience. The rig mainly consists of hoist,hydraulic disc braking system,variable frequency motor,reducer,automatic feeding system,rotating disc and drive device,derrick,drill floor,half-trailer and controlling system. The test and application indicates that the maximum hook load of the drill rig reaches the design demand and meet the requirement of φ114 mm drill pipe in the well of 4000m. It features simple structure,convenient installation,rapid,stable and reliable transporting and adaptability for hostile environment.
