description The utility model discloses a rolling type electric ignition and monitoring system for combustion of oil in situ. The rolling type electric ignition and monitoring system comprises a gas injection pipe column (16) arranged on the lower portion of a wellhead (7) and a coiled tubing (25) which can be inserted in the gas injection pipe column (16) downwardly along the axis of the gas injection pipe column (16). An electric igniter (21) and an igniter temperature measuring device (22) which is used for monitoring the electric igniter (21) are arranged in the coiled tubing (25). The electric igniter (21) and the igniter temperature measuring device (22) are connected with a signal acquisition control cabinet (12) outside the wellhead (7) through a power and temperature measuring cable (24) arranged in the coiled tubing (25). The electric igniter (21) comprises a tubular protecting bush (27). A heating wire (28) and insulating packing (30) are arranged in the protecting bush (27). The electric igniter is arranged i
