Description

Novel ignition gun and ignition device Technical Field The utility model relates to the technical field of oil and gas exploitation equipment, in particular to a novel ignition gun and an ignition device. Background In the petroleum drilling process, when drilling to a high-pressure oil-gas layer, if the liquid column pressure of the drilling fluid is lower than the pressure of the oil-gas layer, the high-pressure oil-gas flow can invade a shaft and gradually rise to a wellhead, so that the drilling fluid is ejected out to form overflow or kick. At this time, the drilling worker closes the blowout preventer to take corresponding effective measures such as throttling, blowout opening and the like. The natural gas directly discharged needs to be ignited and burnt, otherwise, the natural gas is mixed with air to a certain proportion, the risk of explosion exists, and the discharged gas also contains harmful gases such as H 2 S and the like, so that the life of people can be endangered.
