在借鉴DQ70BS顶驱成功经验和成熟技术的基础上,开发了DQ40BC交流变频顶部驱动钻井装置。这种装置是一种机电液信息一体化的钻井设备,由动力水龙头、管子处理装置、导轨与滑车、液压传动与控制系统、电气传动与控制系统,以及辅助装置等部分组成,满足4000m钻机的使用要求。武-1井是采用多项世界先进钻井测井技术的羽状分支井,新研制的DQ40BC顶驱在该井首次使用,在钻井作业中表现优异,经受了严峻的考验,圆满完成了钻井任务。
Based on the successful experience and mature technology of DQ70BS top drive, DQ40BC AC variable frequency top drive drilling device was developed. This device is a mechanical and hydraulic information integration drilling equipment, the power faucet, pipe handling device, guide and pulley, hydraulic transmission and control system, electric transmission and control system, and auxiliary devices and other components to meet the 4000m rig Requirements. Wu-1 well is a feathery branch well that uses many of the world’s most advanced well logging technologies. The newly developed DQ40BC top drive was first used in the well and performed well in drilling operations. It has withstood severe tests and successfully completed the drilling mission .
