Abstract
The regenerating method of oil field perforator includes polishing holes, leveling, eliminating burs, secondary reaming to form certain taper, blocking holes with welded metal pads or adhered rubber pads, pressure test, and inspection. The regeneration can save material and lower production cost, and is especially suitable for the reuse of perforator of 102 mm and 127 mm diameter.
Description
Technical field
The present invention relates to a kind of regeneration recovery method of oil-field gun perforator, be specifically related to a kind of method that the barrel of used Φ 102mm on the oil field or Φ 127mm perforating gun is carried out regeneration.
Background technology
At present, the Φ 102mm that uses in the oil field or the barrel of Φ 127mm perforating gun can produce after using for the first time and friedly portal and damage, have shell exploded the back around a lot of apertures appear, owing to there is not suitable method that this Φ 102mm or Φ 127mm perforating gun are repaired, therefore often see in the oil field many only be used once Φ 102mm or Φ 127mm perforating gun because shell explodes into aperture and can't repair, and fall as waste disposal, cause raw-material waste, also increased cost of production.
Summary of the invention
Thereby use once the back can't repair the deficiency that can not re-use because of the aperture that produces in order to overcome existing oil field Φ 102mm or Φ 127mm perforating gun, the invention provides a kind of regenerating method for oil field perforator, can repair the aperture of gun perforator barrel with this method, make it and to utilize once more, save material and reduce production costs.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of regenerating method for oil field perforator, the step of described renovation process is:
(1) all apertures on the gun perforator barrel is polished with making turbine, tie, the burr polishing around the hole;
(2) with drilling machine the aperture on the gun perforator barrel is carried out reaming and handle, carry out twice reaming altogether, secondary aperture is greater than primary aperture, after reaming finishes, make aperture in the aperture of barrel outer wall greater than aperture at the barrel inwall;
(3) in aperture, carry out shutoff, combine with making hole wall close and firm on plug and the gun perforator barrel with plug;
(4) gun perforator barrel that shutoff is finished is suppressed check.
The barrel of described perforating gun is Φ 102mm or Φ 127mm.
The described plug that carries out shutoff in the barrel aperture can be the metal planchet, and described method for blocking is welding.
The described plug that carries out shutoff in the barrel aperture also can be rubber pad, and described method for blocking is for being glued.
The inventive method is owing to carry out shutoff to aperture with plug and make it to be combined as a whole with pipe shaft aperture hole wall close and firm ground, and is up to the standards through suppressing, so can reclaim and reuse.
The invention has the beneficial effects as follows:
1, with the oil field Φ 102mm of the inventive method reparation or Φ 127mm perforating gun through field trial, suppress check, interior pressure can reach 30 MPas, its resistance to pressure and other performance indications are identical with new perforating gun, making originally, unserviceable waste product is able to regeneration, saved resource, save raw material, reduce production costs.
2, the employed equipment of the inventive method is simple, and capital equipment is drilling machine, beats turbine, electric welding machine, pressure testing machine, is general machinery equipment, therefore is convenient to applying of the inventive method.
The specific embodiment
The present invention is further described below in conjunction with a specific embodiment
The concrete implementation step of present embodiment regenerating method for oil field perforator is:
(1) aperture on oil field Φ 102mm or the Φ 127mm gun perforator barrel is polished with making turbine, tie, the burr polishing around the hole.
(2) with drilling machine the aperture on the gun perforator barrel is carried out reaming and handle, carry out twice reaming altogether, for the first time with 16
#The drill bit reaming is for the second time with 24
#Drill bit carries out reaming, make aperture in the aperture of barrel outer wall greater than aperture at the barrel inwall.
(3) in aperture, carry out shutoff, combine with making aperture wall close and firm on plug and the gun perforator barrel with plug.Because aperture forms certain tapering after twice reaming, more help combining closely of plug and hole wall.
Plug in the inventive method can be the metal planchet of 18mm * 8mm, and its method for blocking is for to weld with electric welding machine.Used welding rod is tied 557 welding rods for knot 556-or is tied 506 or tie 507 welding rods
Plug in the inventive method also can be rubber pad, and this rubber pad is taper, and its diameter at butt end is 24mm, and top diameter is 18mm, and thickness is 8mm.The method of shutoff is for to carry out bonding with 101-102 glue.
(4) gun perforator barrel that shutoff is finished is suppressed check, can come into operation after qualified.
The present invention is applicable to used Φ 102mm, Φ 127mm gun perforator barrel on the oil field is recycled, and can repeatedly be reclaimed.
