In the operation of windowing sidetracking, the whipstock and the setting device are guaranteed to be reliably set and sealed, and whether the track of the well bore of the windowing sidetracking can enter the designed target point is directly influenced. The setting tool must ensure effective setting while downhole, as well as withstand weight-on-bit and cutting torque from the drill bit during the windowing process. If the setting device is set and sealed to lose efficacy in the windowing sidetracking process, slippage and deflection occur, the position state of the whipstock is directly changed, and further windowing position errors are caused, and windowing sidetracking operation fails under severe conditions. Therefore, ensuring that the setting device does not deflect is one of the key technologies for window sidetracking operation.
