Abstract
The utility model discloses a composite energy-containing spring frame for a perforating device of an oil-gas field, which solves the problem that the metal spring frame does not contribute to the eyelet extending suture of the perforations. The composite spring frame is composed of a spring frame body and a centering ring, wherein the centering ring is connected and fixed to both ends of the spring frame body through orientation screws, the side face of the centering ring is provided with locating pin holes, and the centering ring is positioned by locating pins; the wall of the spring frame body is provided with bullet holes in helical mode. The utility model is characterized in that the outer wall of the spring frame body is provided with a gunpowder layer and has an integral structure of cylinder-shaped double layers. The utility model not only has the advantages of the metal spring frame, but also has the effects of increasing the perforation diameter, crushing perforation compaction belts, increasing the depth of making suture of the perforation, etc. The utility model is the integral type spring frame and is very simple and convenient when used at site by being assembled with perforating bullets, detonating cords and nonels. The utility model is mainly used for the underground perforating devices of the oil-gas field.
Description
Technical field
The utility model relates to a kind of compound energy firing mount that contains that is used for oil gas well downhole perforation device, is made up of firing mount body, centering ring, belongs to perforating system, is mainly used in the oil gas field downhole perforation.
Technical background
The firing mount that is used for the perforating oil gas well device at present has nonmetal firing mount and metal firing mount two classes.The intensity of nonmetal firing mount is low, and easy deformation under hot environment can cause the variable in distance between perforating bullet phase angle and the perforating bullet, makes the perforation trueness error become big, influences perforation efficiency.Metal firing mount intensity height plays the accurate positioning action of perforating bullet.Chinese patent 01233448.0 " a kind of metal firing mount that is used for downhole perforation " discloses a kind of simple in structure, positioning accuracy is high and cost is low metal firing mount of being made up of firing mount body and gland.This metal firing mount uses in perforating gun, can not produce high temperature, high-pressure combustion gas to the preforation tunnel secondary pulse, can not eliminate the perforation compaction band, also can not make the seam degree of depth to perforation and contribute.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art existing metal firing mount intensity height is provided, the advantage that the perforating bullet positioning accuracy is high has a kind of compound energy firing mount that contains that is used for the oil gas field perforating system that preforation tunnel is prolonged the seam effect again.
Design of the present utility model: design a kind of cartridge type two-layer compound firing mount body.Internal layer is a metal, makes its firing mount body have the intensity of metal firing mount, plays the positioning action of perforating bullet; Skin is a gunpowder, and the detonation wave after being ignited by perforating bullet ignites, and the jet that the high pressure of formation and high-temperature combustion gas lag behind perforating bullet impacts preforation tunnel, thereby plays further broken perforation compaction band, improves perforation and wears dark effect.
In order to solve the problems of the technologies described above, the utility model is compound contain can firing mount by firing mount body 1, centering ring 6, form.Wherein centering ring 6 is fastened on the two ends of firing mount body 1 by directional bolt 5, and there is shop bolt hole 8 side of centering ring, shop bolt 7 location centering rings 6 on it.Have shell hole 4 on the wall of firing mount body 1 in a spiral manner, be characterized on firing mount body 1 outer wall gunpowder layer 2 being arranged, be the double-deck overall structure of cylinder type.
The thickness of firing mount body 1 is 2-6mm, can be 20
#Steel or 20Cr material.
The thickness of gunpowder layer 2 is 2-6mm, and it is the spiral propagation of explosion passage of 6-10mm that width is arranged between the shell hole 4 thereon.
The gunpowder layer can be single-base powder, double-base powder or composite propellant.
After adopting such structure, the utility model is compound to contain the positioning action that can firing mount have both played perforating bullet, broken perforation compaction band is arranged again and prolong the effect that perforation is made the seam degree of depth.Owing to be the monolithic firing mount, when using at the scene and perforating bullet, detonating fuse, detonator assembling very simple and convenient.Both can be used for having the composite perforation gun of relief hole, can be used for the conventional perforating gun of blind-hole type again.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 be the utility model compound contain can firing mount partly cut open figure.
The specific embodiment
Can be made up of firing mount body 1, centering ring 6 by firing mount compound containing shown in Figure 1.On the wall of firing mount body 1 in a spiral manner 30 degree have a shell hole 4 to 90 degree, the diameter dimension of shell hole 4 is definite according to the external diameter of the perforating bullet that will assemble.On firing mount body 1 outer wall gunpowder layer 2 is arranged, adopt casting process to make gunpowder, form whole two-layer composite attached on firing mount body 1 external surface.Gunpowder layer 2 can be single-base powder, double-base powder and composite propellant, and the thickness of this gunpowder layer 2 is 2-6mm, and it is 6-10mm spiral propagation of explosion passage 3 that width is arranged between shell hole 4, places the detonating fuse that connects perforating bullet when being used to assemble.Centering ring 6 is fixedly connected on the two ends of firing mount body 1 by directional bolt 5, has shop bolt hole 8 on the side of centering ring 6, and with shop bolt 7 location.
Of the present utility model compound contain can firing mount at the scene with the supporting uses of parts such as perforating bullet, detonating fuse, detonator, assembling is very simple and convenient.Both can be used for having the composite perforation gun of relief hole, can be used for the conventional perforating gun of blind-hole type again.And have broken perforation compaction band and increase perforation and make the seam degree of depth.
