| Zusammenfassung: | The invention provides ocean perforation equipment and method, the ocean perforation equipment and method are used for perforation of an ocean high-temperature and high-pressure well, the ocean perforation equipment comprises a casing pipe, a first initiating explosive device, a perforation gun and a second initiating explosive device, and the casing pipe is arranged in the ocean high-temperature and high-pressure well. The first initiating explosive device is arranged in the sleeve. The perforating gun is arranged in the casing pipe, and one end of the perforating gun is connected with one end of the first initiating explosive device. The second initiating explosive device is arranged in the casing pipe, and one end of the second initiating explosive device is connected with the other end of the perforating gun. The problem that when an existing perforating device is used for negative pressure perforation of a marine high-temperature and high-pressure well, dud bullets are prone to occurring, and consequentl |
