Abstract
The invention discloses a packaging structure of a compound perforating bullet. The packaging structure of the compound perforating bullet comprises an asbestos column or an asbestos tube inserted into a lined-cavity charge and a connection kit, and the asbestos column or the asbestos tube extends into the lined-cavity charge from the bottom part of the connection kit. In order to not affect the operational performance of the compound perforating bullet and ensure the safety performance of the product, the relational expression between the length h of the asbestos column or the asbestos tube and the radius R is h=k[H-Rcot(theta/2)]; the outer sides of the lined-cavity charge and the connection kit are coated by asbestos cloth; the compound perforating bullet coated by the asbestos cloth is put into a paper box; the paper box is sealed by tin foil; two paper boxes coated by the tin foil are divided into upper and lower layers to put in a carton; the connection kit of the compound perforating bullet in the upper paper box is arranged downwards, and the connection kit of the compound perforating bullet in the lower paper box is arranged upwards. By adopting the packaging structure disclosed by the invention, the performance of the compound perforating bullet is not affected, and the safety and the reliability of the compound perforating bullet in storage and transportation can be ensured.
Description
Technical field
The present invention relates to the packaging structure of perforating bullet, specifically a kind of packaging structure with the composite perforating charge connecting medicine box.
Background technology
Current composite perforating charge is the compound action product that composite joint medicine box is formed on deep penetration lined-cavity charge basis.Composite perforating charge operation set perforation, High-Energy Gas Fracturing Technology in one, can realize once constructing, the oil gas field volume increase of multi-efficiency, synergy object, there is good market application foreground.
Just because of the energy of composite perforating charge continues superposition, make it adopt common manner of packing to there is potential safety hazard or emergency risk in transit, be particularly unfavorable for the outlet transport of product, make the popularization of composite perforating charge be subject to larger limitation.
Summary of the invention
The potential safety hazard occurred in storage, transportation in order to avoid composite perforating charge or emergency risk, strengthen storing reliability, the invention provides a kind of composite perforating charge packaging structure.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of composite perforating charge packaging structure, comprises the asbestos post in insertion lined-cavity charge and connection medicine box or asbestos pipe.Asbestos post or asbestos pipe extend in lined-cavity charge bottom connection medicine box, in order to not affect the functional performance of composite perforating charge, ensure again the security performance of product, the relational expression of asbestos post or asbestos pipe length h and its radius R is: h=k [H-Rcot(θ/2)]; In formula, h: asbestos post (asbestos pipe) length; H: composite perforating charge height, value 70 ~ 100mm; θ: Cone Angle of Liner, value 39 ° ~ 52 °; R: asbestos post or asbestos pipe radius, value 1 ~ 10mm; K: correction factor, value 0.6 ~ 0.95.
The present invention changes the packaged form of existing composite perforating charge, asbestos post is inserted in composite perforating charge, when a composite perforating charge is blasted, its metal jet excited meets with asbestos post at the formation initial stage, metal jet is cut off by asbestos post, thus reduce the acting ability even consuming metal jet, make contiguous composite perforating charge induced detonation can not occur.Through lot of experiments checking, when detonation by influence or when lighting in individual packages a certain composite perforating charge, burning or blast also can not be propagated in package, can not cause the harm to surrounding environment.Even if eight packages be deposited in together carry out outside bonfire test, also detonation, detonation or blast can not be there is.
Adopt the packaging structure described in invention not affect composite perforating charge performance, can ensure that composite perforating charge is safe and reliable in storage and transport.Through national industrial explosive material Quality Supervision and Inspection Center to the composite perforating charge under this packaged form, carry out the test of danger classes subitem by the United Nations's pertinent regulations, defined the level as 1.4D, reach the standard of transporting safely.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1-asbestos post or asbestos pipe, 2-lined-cavity charge, 3-connects medicine box.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical scheme that application claims is protected is illustrated.
Composite perforating charge primarily of lined-cavity charge be connected medicine box composition.Composite perforating charge packaging structure of the present invention, comprises the asbestos post in insertion lined-cavity charge 2 and connection medicine box 3 or asbestos pipe 1.Asbestos post or asbestos pipe 1 extend in lined-cavity charge bottom connection medicine box 3, in order to not affect the functional performance of composite perforating charge, ensure again the security performance of product, the relational expression of asbestos post or asbestos pipe 1 length h and its radius R is: h=k [H-Rcot(θ/2)]; In formula, h: asbestos post (asbestos pipe) length; H: composite perforating charge height, value 70 ~ 100mm; θ: Cone Angle of Liner, value 39 ° ~ 52 °; R: asbestos post or asbestos pipe radius, value 1 ~ 10mm; K: correction factor, value 0.6 ~ 0.95.
In order to improve storing safety further, lined-cavity charge 2 wraps up with the outside asbestos cloth 4 being connected medicine box 3.Be wrapped in by composite perforating charge in asbestos cloth, when burning occurs for gunpowder in the connection medicine box of a composite perforating charge, asbestos cloth can stop other to connect gunpowder in medicine boxs to sacrifice one's life for combustion.
Finally, the composite perforating charge individual layer wrapped with asbestos cloth puts into carton, carton tinfoil paper seals, wrap with tinfoil paper two cartons are divided and is two-layerly up and down put in carton, composite perforating charge in upper tray connects medicine box 3 down, and the composite perforating charge in MP tray connects medicine box 3 and places upward.
