    摘要: This disclosure is related to a perforator tool and a method of using the perforator tool to perforate a formation. The perforator tool can include a first and second sleeve and optionally a third sleeve. The perforator tool can also include at least one perforation opening and at least one circulation port. The sleeves are slidably disposed within the perforator tool and can be displaced to permit perforation of the formation, block the perforation openings and open circulation ports.
