Abstract
The utility model discloses a rapid-connection type perforating gun. The rapid-connection type perforating gun comprises perforating gun bodies which are connected mutually, wherein the connecting ends of the perforating gun bodies are provided with L-shaped notches, the other end of each perforating gun body is provided with a limiting clamping edge which corresponds to the corresponding notch, a hole is formed in an upper clamping border of each limiting clamping edge, a spring is arranged in each hole, a clamping pin is fixedly arranged on each spring and extends out of the corresponding hole, and a retreat-preventing pit is formed in each notch, and corresponds to the corresponding clamping pin. The rapid-connection type perforating gun is simple in structure and reasonable in design, separation is prevented, rapid butt joint can be achieved, connection is firm, and operation is safe and reliable.
Description
Technical field
The utility model relates to oilfield well completion technical field, is specifically related to a kind of fast joint type perforating gun.
Background technology
At present, in oil field or other drilling well drilling operation, the rifle body of the perforating gun often using is divided into multistage, needs to interconnect prolongation between them.In the prior art, the connection of perforating gun is a kind of is that screw thread by perforating gun rifle body termination is threaded, and this connected mode efficiency is lower, and operation is wasted time and energy, in use the easy loosening potential safety hazard that exists; Another kind is to connect respectively by pin and box sub, utilizes the connected mode structure of pin and box sub too complicated, and because structural limitations causes perforation blind area larger, the continuity of perforation is affected, and directly affects the liquid measure of adopting after perforation.
Summary of the invention
The purpose of this utility model is exactly the defect existing for prior art, provides a kind of simple in structure, reasonable in design, prevents from throwing off, and can realize rapid abutting joint, be connected firmly, and the reliable fast joint type perforating gun of job safety.
Its technical scheme is: fast joint type perforating gun, comprise interconnective perforating gun rifle body, the link of described perforating gun rifle body is provided with L-type breach, the other end of described perforating gun rifle body is provided with the spacing edge corresponding with breach, the upper card of described spacing edge is provided with hole along place, in described hole, be provided with spring, be fixed with the bayonet lock that stretches out described hole on described spring, described indentation, there is provided with the anti-back pit corresponding with bayonet lock.
Described breach and spacing edge are at least two, are evenly distributed on the end of perforating gun rifle body.
The link of described perforating gun rifle body is provided with connecting thread.
Described L-type breach comprise the gap portion parallel with axis and with the vertically disposed Access Division of gap portion, described anti-back pit is arranged on Access Division.
The utility model compared with prior art, has the following advantages: simple in structure, reasonable in design, prevent from throwing off, and can realize rapid abutting joint, be connected firmly, job safety is reliable.
Accompanying drawing explanation
Fig. 1 is the system schematic of a kind of embodiment of the utility model.
The specific embodiment
With reference to Fig. 1, fast joint type perforating gun, comprise interconnective perforating gun rifle body 1, the link of described perforating gun rifle body 1 is provided with L-type breach 2, the other end of described perforating gun rifle body 1 is provided with the spacing edge 3 corresponding with breach 2, and the upper card of described spacing edge 3 is provided with hole 4 along place, is provided with spring 5 in described hole 4, on described spring 5, be fixed with the bayonet lock 6 that stretches out described hole 4, described breach 2 places are provided with the anti-back pit 7 corresponding with bayonet lock 6.
Described breach 2 and spacing edge 3 are at least two, are evenly distributed on the end of perforating gun rifle body 1.
The link of described perforating gun rifle body 1 is provided with connecting thread 8.By connecting thread 8, realize and being threaded.
Described L-type breach comprise the gap portion 9 parallel with axis and with the vertically disposed Access Division 10 of gap portion 9, described anti-back pit 7 is arranged on Access Division 10.
When perforating gun rifle body 1 need to connect, the spacing edge of a perforating gun rifle body 3 is inserted in the breach 2 of another perforating gun rifle body, from gap portion 9, enter, then rotating gun body, spacing edge 3 10 is moved to Access Division, thereby by bayonet lock 6 Compress Springs 5 and bayonet lock 6 is all entered in hole 4, when continuing rotation, when bayonet lock 6 is corresponding with anti-back pit 7 on spacing edge 3, bayonet lock 6 is upspring to be entered in anti-back pit 7, prevent that like this vibrations because of body of perforating gun, rotation etc. from coming off, easy to connect, firm, safe and reliable.
The utility model is simple in structure, reasonable in design, prevents from throwing off, and can realize rapid abutting joint, is connected firmly, and job safety is reliable.
