摘要（英）：

The invention relates to a fishing device for a wireless while-drilling instrument in oil drilling, comprising an electric fisher, a weighting rod, a rotary joint, a cable adapter joint, and an electric fisher ground controller arranged on the surface of a well and used for controlling the electric fisher. The upper end of the electric fisher is connected with the lower end of the weighting rod. The upper end of the weighting rod is connected with the lower end of the rotary joint. The upper end of the rotary joint is connected with the lower end of the cable adapter joint. The electric fisher ground controller passes through the cables of the cable adapter joint, the rotary joint and the weighting rod to be electrically connected with the electric fisher. The fishing device has a simple structure, is convenient to use, and is suitable for field drilling operation.
