Abstract
The utility model provides an integral type perforation rifle. The body of a gun of this perforation rifle has designed the structure that can directly carry out interconnect, and it is loaded down with trivial details to have solved between traditional perforation rifle body of a gun the connection process, can't directly carry out the problem of connecting between the body of a gun. Body of a gun right -hand member carry out jumping -up thickening, its wall thickness degree is greater than left end wall thickness degree. Body of a gun right -hand member set up external screw thread and seal structure, body of a gun left end be provided with internal thread and seal structure, easy installation, integral type perforation rifle has simple structure, convenient and practical, the easy characteristics of interconnect.
Description
Technical field
The utility model is related to oil field well perforating technology field, it is adaptable to the perforating appliances in completion practice, specifically
A kind of integral type perforating gun.
Background technology
Increase and the constantly improve of Perforating Techniques with perforating job, various types of perforating guns meet the tendency of and
It is raw.Perforating gun raw material domestic at present all using etc. wall thickness seamless steel pipe, it is contemplated that body of a gun bonding strength is wanted during perforation
Ask, the body of a gun is designed as two ends female thread structure, perforating gun when operation field assembling is used, all using the body of a gun --- connect
Head --- between this combination connecting mode of the body of a gun, i.e., two or the branched perforating gun body of a gun connected using transition joint
Connect, this mode that is linked and packed there are problems that in actual application, complex operation；Accessory joint is heavier, removes by hand
It is also easy to produce in fortune, assembling process and is collided with, cause screw thread or sealing face damage, operation field dust storm is big sometimes for influence connection effect,
Dust impurity easily enters joint screw thread part, it is necessary to cleaning, labor intensive in time.This structure makes the company between adjacent two rifles
Connect distance more long, cause perforation blanking length larger, accordingly reduce perforation hole count, decrease the formation of oil flow channel.
The content of the invention
The purpose of this utility model is in order to present in solving to be linked and packed between the above-mentioned branched existing perforating gun body of a gun
Problem, so provide one kind be linked and packed conveniently, reduce labor intensity of operating staff, save perforation cost a kind of integral type penetrate
Hole rifle.
The purpose of this utility model is achieved through the following technical solutions：
The handling process that jumping-up thickening is carried out to wall thickness perforation casing one end tube wall such as conventional is employed, makes perforation casing former
Material becomes wall thickness tube by waiting wall thickness tube to turn into.
A kind of integral type perforating gun, including the body of a gun that can be directly connected to each other, described body of a gun right-hand member set external screw thread and
Sealing structure, described body of a gun left end is provided with internal thread and sealing structure, and the right-hand member of the described body of a gun can be with another body of a gun
Left end be directly connected to by screw thread, can be mutually sequentially connected between every two body of a guies, formed perforating gun string.
Further, a described type body of a gun external diameter is 102mm, a length of 1-4 meters, and stub end uses Tr90X4 sizes
Trapezoidal internal thread and sealing structure, depth is 74mm, and wall thickness is 9mm；Small head end uses the trapezoidal external screw thread of Tr90X4 sizes
And sealing structure, length is 74mm, and microcephaly's end pipe material has carried out thickening treatment, and wall thickness reaches 19mm, and length is 125mm.
Further, the small head end of the body of a gun is provided with the draw-in groove that width is 22mm.
The beneficial effects of the utility model are：By using the technical solution of the utility model, directly connect between perforating gun
Connect, the assembly connection operation more simple possible of operation field alleviates the labour intensity of operating personnel, improves operating efficiency.
When branched integral type perforating gun is installed to be connected without transition joint, perforating gun attachment structure is simplified, reduced operating cost.
Perforation blind area is short, in identical core intersection, is contrasted with identical conventional perforation mode, can increase perforation quantity, improves oil stream
Passage.The product category of perforating gun is expanded, according to the perforating gun structure that this is innovated, can according to actual needs design one is
The integral type perforating gun of row diameter.
Brief description of the drawings
Fig. 1 is the utility model assembly structure figure.
Fig. 2 is the utility model body of a gun structural representation.
Specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing：The present embodiment is with the utility model skill
Implemented under premised on art scheme, given detailed implementation method, but protection domain of the present utility model be not limited to it is following
Embodiment.
As depicted in figs. 1 and 2, a kind of integral type perforating gun involved by the present embodiment, including the body of a gun, with the branched body of a gun
The function that can be directly connected to each other from beginning to end, described body of a gun left end uses internal thread and design of Sealing Structure, and right-hand member uses outer spiral shell
Line and design of Sealing Structure, the internal and external screw thread nominal dimension at two ends are identical, to ensure the intensity of gun barrel string after connecting, using rifle
Structure design of the tubing thickness more than tubing thickness at left end at body right-hand member；
Used as one embodiment of the present of invention, described integral type perforating gun body of a gun external diameter is 102mm, and overall length is 1-4 meters,
Left end uses the trapezoidal internal thread and sealing structure of Tr90X4 sizes, and depth is 74mm, and wall thickness is 9mm；Right-hand member uses Tr90X4
The trapezoidal external screw thread and sealing structure of size, length are 74mm, and the tubing of right-hand member has carried out thickening treatment, and wall thickness reaches 19mm,
Length is 125mm.Primarily to making two rifle junctions that there is enough intensity, the cracking of pipe end is caused to damage after preventing detonation
It is bad.
Used as one embodiment of the present of invention, integral type perforating gun gun barrel right-hand member endoporus is stepped hole, the diameter of stepped hole
Size is 66mm, when facilitating perforating job in perforating gun firing mount connection.Right-hand member outer wall is provided with the draw-in groove that width is 22mm, uses
The positioning when body of a gun connects and go into the well connection.
Because coupling part length reduces, so as to reduce perforation blind area, when core intersection is identical, increase is conducive to penetrate
Hole number.
Should there are pipette tips, gun breech or other perforating appliances parts to be attached thereto during integral type perforating gun application and keep sealing.
The above, only the utility model preferably specific embodiment, these specific embodiments are all based on this
Different implementations under utility model general idea, and protection domain of the present utility model is not limited thereto, it is any ripe
Those skilled in the art are known in the technical scope that the utility model is disclosed, the change or replacement that can be readily occurred in, all
Should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with claims
Protection domain is defined.
