Abstract
The present invention discloses a regeneration technology for gun perforator barrels in oil fields, which comprises the steps that small holes on the gun barrels are processed and mended, the annular protrusions on the barrel wall of the processed gun barrels are processed and shaped by special dies and equipment, the small holes on the gun barrel after shaping process are expanded and processed, and certain welding rods are used for welding. The regeneration technology for gun perforator barrels in oil fields provided by the present invention makes the wasted gun barrels reused by the special equipment, saves resources, reduces production cost, and is a technique which worth popularizing and using.
Description
The present invention relates to the recovery method of oil-field gun perforator barrel, specifically a kind of method that makes the oil-field gun perforator barrel regeneration.
Oil-field gun perforator barrel can deform and damage after once using, heave as the pipe shaft part, form annular projection, and a lot of apertures appear on the gun body pipe, owing to there is not suitable method that these gun body pipes are repaired, thereby often can see that on the oil field many gun body pipes that only are used once can't repair because of the projection that forms and by the aperture that shell explodes, fall as waste disposal, cause raw-material huge waste, increased cost of production.
Purpose of the present invention just is can't repair after oil-field gun perforator barrel once uses at present, the situation of regeneration, a kind of new method is provided, the equipment that this method is selected for use is simple, the method easy operating is promoted, and, makes to be considered to unserviceable waste product and to be able to regeneration with newly gun perforator barrel is identical through the gun body pipe resistance to pressure of its reparation and other performance indications, save resource, reduced cost of production.
The concrete technical scheme of oil-field gun perforator barrel renovation process of the present invention is:
At first the aperture on the gun body pipe pipe shaft being repaiied the hole with the polishing abrasive machine handles, the gun body pipe of repairing after handle in the hole is handled the annular projection shaping of body of a gun tube wall with particular manufacturing craft and equipment, the aperture that shaping is handled on the gun body pipe of back carries out the reaming processing, and weld with certain welding rod, take pictures then and suppress check.
Wherein, the handled gun body pipe of the present invention is φ 89 * 7 (mm) import special steel pipe special-purpose in the oil well logging perforation;
Described mould is homemade a kind of particular manufacturing craft that uses with other coordinative composition of equipments, and wherein the material of mould is 45
#Steel, it is φ 90mm, that be of a size of 60 centimeters * 50 centimeters sizes, shape structure as shown in Figure 1 that mould can be made diameter by machined into, wherein the upper module of the mould tup that is spirally connected.The lower module of the mould workbench that is spirally connected, when shaping is carried out, upper module with tup with 750 Kilogram Force Per Meters
2Pressure pound down, just form the hole, garden of φ 90mm during with the complete interlock of lower module.
Among the present invention used other corollary equipments it draw together steel tube regeneration machine that the air hammer that produces in Qiqihar, the hydraulic press of going up marine products, Henan produce or the kiloton pressure of going up marine products.
Below in conjunction with drawings and Examples enforcement of the present invention is elaborated.
Fig. 1 is mould of the present invention and corollary equipment structural representation thereof;
Fig. 2 is Fig. 1 the latter half vertical view.
Each label is expressed as respectively among the figure: air tup 1, bolt 2, upper module 3, lower module 4, workbench 5.
During method concrete operations of the present invention, at first, used gun body pipe is handled aperture on its pipe shaft with making turbine, remove burr, and the burr of whole steel pipe is removed, carry out repair process with mould, during reparation gun body pipe is placed the indent of lower module 4, repair 1 pair of gun body pipe prominence of tup with upper module 3 combinations, wherein on mould per 20 centimeters advance once, upper module 3 with tup 1 with 750 Kilogram Force Per Meters
2Pressure pound down, just form the hole, garden of φ 90mm during with the complete interlock of lower module 4, annulus projection on the gun body pipe after the reparation can be eliminated fully, then aperture being carried out reaming handles and welds with certain welding rod, welding rod used during welding is knot 556, commercially available, 800 Kilogram Force Per Meters are analyzed and used to the repair efficiency after the welding through X-ray diffraction crystalline phase
2High-pressure pump suppress experimental results show that qualified.
This kind oil-field gun perforator barrel renovation process provided by the present invention by using purpose-made device, makes existing many gun body pipes that is considered to waste product be able to regeneration, has saved resource, reduce production costs, and be a method that is worth of widely use.
Claims (2)
1, oil-field gun perforator barrel renovation process, comprise that the aperture on the gun body pipe pipe shaft is repaiied the hole with the polishing abrasive machine to be handled, the gun body pipe of repairing after handle in the hole is handled the annular projection shaping of body of a gun tube wall with particular manufacturing craft and equipment, the aperture that shaping is handled on the gun body pipe of back carries out the reaming processing, and welds with welding rod; Described particular manufacturing craft is that diameter is structure φ 90mm, that be of a size of 60 centimeters * 50 centimeters sizes, the upper module of the mould tup that is spirally connected wherein, the lower module of the mould workbench that is spirally connected, when shaping is carried out, upper module with tup with 750 Kilogram Force Per Meters
2Pressure pound down, just form the circular hole of φ 90mm during with the complete interlock of lower module.
2, the described oil-field gun perforator barrel renovation process of claim 1, wherein said welding rod is knot 556.
