Beschreibung
Zusammenfassung:	The invention discloses a windable electric ignition and monitoring system for in-situ combustion, which comprises a gas injection tubular column (16) arranged at the lower part of a wellhead (7), and a coiled tubing (25) capable of being inserted into the gas injection tubular column (16) along an axis of the gas injection tubular column (16) downwards, wherein the coiled tubing (25) is internally provided with an electric igniter (21) and an igniter temperature measurement device (22) for monitoring the electric igniter (21); the electric igniter (21) and the igniter temperature measurement device (22) are connected with a signal acquisition control cabinet (12) outside the wellhead (7) by a power and temperature measurement cable (24) arranged in the coiled tubing (25); the electric igniter (21) comprises a cylindrical sheath (27); and the sheath (27) is internally provided with electric heating wires (28) and insulation packing (30). Since the electric ignition device is arranged in the coiled tubing, the
