| The work aims to solve the potential safety hazard in the well field caused by the premature explosion risk of detonators in the cable perforation process of petroleum exploitation. A safe explosion avoidance ignition device for oil and gas wells was designed. High safety and high current detonators were used in the device. The design scheme of circuit isolation and explosion transmission sequence isolation was adopted. The type selection design and analysis were carried out to the compression spring in the device, and the simulation experiment of device arming and resetting was completed. The designed safe explosion avoidance ignition device met the requirements of pressure conduction by the spring with a cross-sectional diameter of 5 mm and the spring switched the device to a safe state by overcoming the creep property loss after pressure relief, ensuring the safety of the pipe string under construction and not under construction. The device is used in cable perforation operation to improve the reliability and safety of construction and ensure the safety of on-site operators. |
