NEW HIGH PRESSURE CLOSED SYSTEM CABLE PERFORATION EQUIPMENT AND IT’S FIELD TESTING TECHNOLOGY

The purpose and meaning of studying with the new high pressure closed system perforation was expound. The constitute and effect, the technology principle, the main technical target and top technology were expound also. This setting was constituted by high-pressure lubricator, blowout preventer, injection oily pump, closed gate valve and conversion tie-in. The high-pressure cable closed perforation equipment can be used in all kind of oil and gas wells with pressure. It can be used in fishing downhole fish and in bridge plugging in fracturing with pressure. The setting can prevent blowout efficiency and can prevent environment pollution.
