Unlocking energy storage spring triggering device for oil-gas well perforation initiation

The invention relates to an unlocking energy storage spring triggering device for oil-gas well perforation initiation. The unlocking energy storage spring triggering device for oil-gas well perforation initiation is used for triggering an initiator in an initiation device used for triggering oil-gas well perforation, and solves the problems that a spring arranged in the existing triggering device is pre-compressed in the device for a long time, so that the elasticity of the spring fails; and after the potential energy is converted into kinetic energy, the initial energy is reduced, so that the initiator cannot be triggered. Meanwhile, the device is unlocked when the force exerting on the triggering device is greater than the pre-pressure of the spring; the initiation device can be reliably triggered; the problem that the initiation pressure cannot be preset for the initiation device for an oil-gas well is solved; the one-step well-entering perforation success ratio is improved; the construction cost is reduced; and the use is more reliable and safer.
