The invention provides a deviated well in-situ combustion continuous-tube electric ignition tubular column and an ignition method. The tubular column comprises an oil tube, wherein an electric ignition cable and a monitoring cable are arranged in the oil tube; at least one guiding and centering device is arranged between tube sections of the oil tube; a guiding and limiting stopper is arranged on the bottom end of the oil tube; the electric ignition cable penetrates through the guiding and centering device so as to be suspended in the oil tube; the bottom end of the electric ignition cable is connected with an electric igniter; the electric igniter is supported in the guiding and limiting stopper; the monitoring cable respectively penetrates through the guiding and centering device and the guiding and limiting stopper so as to be suspended in the oil tube; the bottom end of the monitoring cable is stretched out of the oil tube so as to be connected with a sensor. Therefore, air can be heated uniformly during a highly-deviated well ignition process, and the highly-deviated well ignition effect is improved; in addition, the monitoring cable is arranged in the oil tube, so that the monitoring cable cannot be stuck by a packer during the process of pulling out the oil tube, the recycle and the reuse of the monitoring cable are realized, and the investment cost is reduced.
