摘　　要：基于无钻机钻探机器人的能源供应和线缆存取的要求,研制了一种井筒电缆存储与释放装置,具备深海深地钻探用电缆的井筒存储和释放功能。结合井下环境、钻探功能和控制要求,对总体结构和运动模态进行了设计,重点对绕线机构和中间连接筒机构进行结构设计和力学分析,并制作样机进行了功能验证。结果表明,研制的井筒电缆存储与释放装置可实现无钻机钻探机器人在3000 m钻深工况下的电缆收放功能。Based on rig-less drilling robots′energy supply and cable access requirements,a wellbore cable storage and release device is developed,capable of cable storage and release in the deep sea and deep formation.Based on the conditions of the downhole environment,drilling function and device control,the whole mechanical structure and operating modes are designed.Especially,the structural stress distributions of winding mechanism and intermediate transition connecting drum are analyzed.Also,a prototype device is manufactured for functional verification.It is shown that the wellbore cable storage and release device is capable of withdrawing and releasing cables under the condition of 3000 m drilling depth with rig-less driller.
