摘　　要：井下智能阀门控制器作为石油勘探开发的主要工具之一,其工作性能直接影响石油生产成本。因供能蓄电池常难以满足其井下长期反复作业的需求,提出一种适应其结构的无线充电装置。采用双螺旋互套式线圈结构,建立井下无线电能传输系统数学模型,分析负载功率给定时系统高效传输的条件,得到影响定功率系统高效传输的重要参数。运用电磁仿真软件设计和详述材料、线圈线径等参数对系统的影响,并经优选后得到一种给定功率时传输效率达93%的井下无线充电装置。The downhole intelligent valve controller is considered as one of the main tools for oil exploration and development,and its performance directly affects the cost of oil production.Considering that its energy-supply battery often cannot meet the needs of long-term repeated operations in the downhole,a wireless charging device adapted to its structure is proposed,in which a double-spiral mutual-casing coil structure is adopted.A mathematical model of the downhole wireless power transmission system is established,the condition for the system’s efficient transmission at a rated load power is analyzed,and the important parameters affecting the efficient transmission are obtained.Electromagnetic simulation software is used in the design,and the effects of device parameters such as device material and coil wire diameter on the system are detailed.In addition,a downhole wireless charging device with a transmission efficiency of93%at a rated power is obtained after optimization.
