At present, there are three common methods of ignition treatment. One is that when the combustible gas in the well is expected to pass through the outlet of the blowout pipeline, cotton yarn is dipped with diesel oil to be ignited and placed at the outlet of the blowout pipeline, and then the gate of the blowout pipeline is opened to ignite the combustible gas in the well through the outlet of the blowout pipeline; the second method is to use a liquefied gas tank to be ignited at the outlet of the blowout pipeline through a thin pipeline, namely, the liquefied gas tank is ignited when combustible gas in the well passes through the outlet of the blowout pipeline; the third one is high voltage pulse ignition, that is, there is a pair of electrodes at the outlet of the blowout pipeline to produce intermittent sparks, which are ignited when the combustible gas in the well passes through the outlet of the blowout pipeline and reaches a certain concentration.
