Abstract

The invention discloses a high energy electronic ignition system for a high pressure gas well, which is suitable for igniting an open flow spout in the petrochemical field, especially the open flow field of the gas well (oil well). The high energy electronic ignition system for the high pressure gas well comprises an input power supply and an open flow device, wherein the input power supply is connected with a host machine of an igniter, the host machine of the igniter is connected with an ignition rod by a flame resistant cable, and the ignition rod is fixed above the open flow device by an ignition rod bracket. The high energy electronic ignition system for the high pressure gas well can solve the problem of various ignition modes that ignited fire is easy to be extinguished by spouted water; and the high energy electronic ignition system has the advantages of high reliability, no potential safety hazard and accurate and efficient ignition performance, and the operation of ignition can still be successfully carried out under the adverse environment in the premise that the gas concentration reaches the lower limit of inflammation concentration.

Description

technical field [0001] The invention relates to an ignition system suitable for directly igniting a blowout port in the petrochemical field, especially in the blowout field of natural gas wells (oil wells). Background technique [0002] Natural gas wells (oil wells) usually discharge a large amount of combustible gas and brine and other substances in the blowout pipeline during the production process or when a blowout occurs. These substances have a fast flow rate and contain flammable and explosive substances such as methane, hydrogen sulfide and sulfur dioxide. , toxic gas, so ignition as soon as possible is one of the most effective measures to reduce casualties. At present, there is no effective way to solve this problem in China. The 11.20 blowout accident in Dazhou occurred because a large amount of high-pressure combustible gas was not ignited at the first time, which made the blowout process out of control. [0003] At present, there are mainly three ignition method...
