At present, after ignition is completed, the mobile electric igniter for the oil field fireflood well needs to be lifted out of the well, when the mobile electric igniter is lifted to a well head, the position of a conical head of the mobile electric igniter needs to be accurately judged between a test valve and a sealer so as to close the test valve, otherwise, the mobile electric igniter and the test valve can be damaged. The existing mode is a human eye identification mode, specifically, a mark is made at a position which is a few meters away from the conical head of the mobile electric igniter before the mobile electric igniter is put into a well, when the mobile electric igniter is lifted to be close to the well head, the mobile electric igniter is carefully and slowly lifted, due to high temperature and high pressure in the well and dirt, the mark is difficult to see clearly, the position of the conical head of the mobile electric igniter is difficult to determine, and accidents are very easy to occur.
Another is an automatic identification method, for example, chinese patent with publication number CN105443115B discloses a device for detecting the position of the end of a mobile electric igniter, as shown in fig. 1, which mainly includes: measuring element 6, rubber pad 7, outer magnetic ring sleeve 8, driven member 9, sheath 10, inner magnetic ring 11, spacer 12, compression spring 13, movable rod 17 and stop ring 25. When the electromagnetic igniter works, under the action of the compression spring 13, the movable rod 17 moves leftwards and simultaneously drives the baffle ring 25 and the inner magnetic ring 11 to synchronously move leftwards, the baffle ring 25 contacts the outer wall of the movable electric igniter 26 to stop moving, and due to the magnetic coupling of the inner magnetic ring 11 and the driven part 9, the driven part 9 and the inner magnetic ring 11 synchronously move, so that the outer magnetic ring sleeve 8 and the rubber mat 7 are driven to move. When the bottom end face 24 of the movable electric igniter lifts up and passes through the stop ring 25, the movable rod 17 continues to move leftwards under the action of the compression spring 13, so that the rubber gasket 7 is driven to move leftwards, the measuring element 6 is triggered to act, an alarm and stop signal is sent out in time, and the wellhead valve 23 can be closed at the moment.
