Abstract
The utility model provides an energy containing bullet support for oil-gas well perforation, which solves the problem that the existing perforation bullet support is easy to loosen and drop in a descending delivery process and height of burst of a perforating bullet cannot be adjusted. The energy containing bullet support comprises a perforation bullet support, compressing blocking pieces are symmetrically arranged above the perforation bullet support, a clamping groove is further arranged on the perforation bullet support, an elastic piece is arranged on the clamping groove, and a boss is arranged on the perforation bullet support. The energy containing bullet support is simple in structure, strong in interwork and interchange adaptability, low in cost, various in structure and capable of replacing synergia perforation drug cakes, and saves space for inside of a perforator. The boss is arranged in the perforation bullet support, so that the height of burst of the perforating bullet can be controlled. The energy containing bullet support can completely replace effects of composite drug cakes, and the energy containing bullet support can be suitable to application of various perforation processes and various perforating bullet types.
Description
Technical field
The utility model belongs to the perforating oil gas well technical field, and particularly a kind of perforating oil gas well can the bullet holder with containing.
Background technology
Perforating bullet is most crucial firer's parts that the perforating oil gas well well-completing process is used; In order to make accurately location and the distribution on its carrier of perforation resilience energy; Employing contains and can the bullet holder carry out fixed limit to perforating bullet, guarantee that not only perforating bullet is not loosening in the course of conveying of going into the well, do not come off, and definite perforating bullet is radially vertical on its carrier, 90 degree phase places are uniformly distributed with; And can rationally confirm the height of burst and the effective stream aperture of perforating bullet, so bullet is holding up crucial effects.Therefore, existing perforating bullet holder exists in the course of conveying of going into the well and is prone to become flexible, is prone to come off, and the height of burst of perforating bullet is non-adjustable.
The utility model content
The purpose of the utility model provide a kind of perforating oil gas well with contain can bullet holder, with solve existing perforating bullet deposit the course of conveying of going into the well in be prone to become flexible, be prone to come off, and the nonadjustable problem of the height of burst of perforating bullet.
The utility model adopts following technical scheme:
A kind of perforating oil gas well comprises the perforating bullet holder with containing the holder of ability bullet, and said perforating bullet holder top is arranged with and compresses fastener, also is provided with draw-in groove in the said perforating bullet holder, and said draw-in groove is provided with elastic component.
Be provided with boss in the said perforating bullet holder.
Said perforating oil gas well uses that to contain can the bullet holder be cylindrical, truncated cone-shaped or elliposoidal.
The utlity model has following advantage:
1. the utility model is simple in structure, joins mutually that to exchange compliance strong, and cost is low;
2. structure variation;
3. in the perforation mechanism, produce high temperature and high pressure gas, preforation tunnel and radial fissure are played synergy and pressure break effect, replaced synergy perforation medicine cake, for saving the space in perforator inside.
4. be provided with boss in the perforating bullet holder, mainly be used for the external assembling perforating bullet in spacing location, can control the height of burst of perforating bullet simultaneously.
The utility model can replace the effect of compound medicine cake fully, is fit to all kinds of gun perforation process and all kinds of perforating bullet type and uses.
Description of drawings
Fig. 1 is the structural representation of first embodiment of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the user mode figure of first embodiment of the utility model;
Fig. 4 is the structural representation of second embodiment of the utility model;
Fig. 5 is the structural representation of the 3rd embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
As depicted in figs. 1 and 2, a kind of perforating oil gas well of the utility model comprises perforating bullet holder 3 with containing the holder of ability bullet, and perforating bullet holder 3 tops are arranged with and compress fastener 1, also are provided with draw-in groove 5 in the perforating bullet holder 3, and draw-in groove 5 is provided with elastic component 2.Be provided with boss 4 in the perforating bullet holder 3.
In this embodiment, it can the bullet holder be cylindrical that the perforating oil gas well use contains.
Be provided with boss 4 in perforating bullet 3 holder, mainly be used for the external assembling perforating bullet in spacing location, can control the height of burst of perforating bullet simultaneously.
Perforating bullet holder 3 forms through mould compacting, cast for energetic material, energetic material be selected from alloy in lightweight powder, the non-metal powder at least a with mix fiery explosive mixing.According to the different energetic material of bullet type different choice.
As shown in Figure 3, in operation field is packed perforating bullet into perforating bullet holder 3, will compress fastener 1 inside bending, compressing fastener 1 then, that perforating bullet holder 3 inner cylinder faces are cooperated with perforating bullet is firm.Form bullet holder assemblies to the perforating bullet that will fix being stuck in tightly in the perforating bullet holder 3, be encased in bullet holder assembly in the perforating bullet carrier then,,, just can carry out next step flow chart bullet holder assembly being stuck in the carrier hole tightly through elastic component 2.
Perforating oil gas well combines with the outside and the perforating bullet carrier that contain the holder of ability bullet, and endoporus and perforating bullet are complementary, and has enough intensity and can satisfy perforating bullet safe and reliable fixing in the transmission course of going into the well; Released energy by detonation impact cutting effect gasification or burning, blast preforation tunnel is produced the effect of time-delay pressure break.
As shown in Figure 4, perforating oil gas well uses and contains and can the bullet holder be truncated cone-shaped.All the other are with embodiment 1.
As shown in Figure 5, perforating oil gas well uses and contains and can the bullet holder be elliposoidal.All the other are with embodiment 1.
