Description

Technical Field

[0001] The utility model belongs to the field of oil and gas exploitation, and particularly relates to an ejection type natural gas igniter. Background Technique

[0002] At present, during the process of oil and gas exploration and development, due to inaccurate investigation of geological layer pressure, low density of drilling fluid and other reasons, natural gas intrusion occurs. Therefore, it is necessary to release the bottom hole pressure to prevent well kick and wellhead pressure. The main component of the gas is natural gas, which also contains toxic gases such as carbon monoxide and hydrogen sulfide. To avoid environmental pollution caused by this gas and threat to the personal safety of oil and gas exploitation personnel, this gas is usually ignited to prevent accidents.

[0003] The commonly used ignition methods at present include manual ignition, high-energy electron ignition and magic bullet ignition. Manual ignition usually uses a hand-held rod ignition or an oil basin ignition. The hand-held rod ignition is relatively close to the ignition point, with risks such as explosion and burning, which may burn the operator; the oil basin ignition is that the operator pulls the steel wire rope to send the ignited oil-containing vessel to the gas discharge port to ignite the gas. This ignition method is prone to accidents such as steel wire rope crossing and the oil-containing vessel being overturned, which is not conducive to the smooth progress of oil and gas ignition. The time required for secondary ignition is long after the first ignition fails. The high-energy electron ignition mechanism has a high degree of automation and can realize remote control ignition. It is usually installed at the end of the gas discharge port. The gas flow rate at the end of the discharge port is large, the oxygen content is thin, and the discharged gas usually contains sediment, water vapor, etc., which makes the electronic igniter easy to fail; the magic bullet ignition is to ignite the magic bullet and put it into the oil and gas discharge area, and use the spark generated by the explosion of the magic bullet to ignite the gas. However, the throwing distance of the magic bullet has a certain randomness, and it belongs to flammable and explosive items, which requires special management and transportation, and the use cost is relatively high.

[0004] In order to be able to remotely ignite the natural gas discharged during oil and gas exploitation due to safety production needs, and to be able to achieve rapid ignition and combustion, there is an urgent need for a remote natural gas ignition mechanism that can perform single-shot continuous ignition from a long distance, improve the ignition success rate, and ensure the safety of oil and gas exploitation.

[0005] In view of the above, this case is thus generated. Content of the Utility Model

The tension spring 102 is used to restore the elastic rope fixator 103, and the elastic rope fixator 103 and the tension spring 102 work together to achieve the tensioning and reset positioning of the elastic rope 101. The elastic rope 101 is made of an elastic material and can be freely stretched within the elastic limit to eject the ignition cartridge in the motion track 105. The traction rope 104 is made of a rigid material and connects the elastic rope fixator 103 and the ejection mechanism servo 107 on both sides of the motion track for the movement of the elastic rope fixator 103, so that the elastic rope 101 is fixed on the elastic rope fixator 103 and the elastic rope fixator 103 is reset. The ejection mechanism servo 107 can rotate to pull the traction rope 104. The transmission mechanism 109 is used to retract the traction rope 104. The transmission belt 108 connects the ejection mechanism servo 107 and the transmission mechanism 109 for driving the transmission mechanism 109 when the ejection mechanism servo 107 rotates.

[0032] S3: Then, press the trigger 301 for ammunition feeding, and the control circuit (not specifically marked in this structure diagram) makes the steering gear 304 of the ammunition feeding mechanism rotate to pull the push block towing rope 306. The push block towing rope 306 makes the push block 302 push the ignition cartridge to enter the firing position from the U-shaped structure 303.
