Abstract
The utility model particularly relates to a two-stage compound energy-containing bullet sleeve which is used in perforation of an oil gas well. The two-stage compound energy-containing bullet sleeve comprises a hollow bullet sleeve, a frustum portion is arranged at the upper portion of the bullet sleeve, and a cylinder portion is arranged at the lower portion of the bullet sleeve. The two-stage compound energy-containing bullet sleeve is characterized in that a cylinder positioning bulge is arranged at the upper end of the frustum portion of the bullet sleeve, a guide groove of a detonating cord is arranged on the positioning groove, and compound gunpowder chambers are arranged on both sides of the upper portion of the cylinder portion of the bullet sleeve. The two-stage compound energy-containing bullet sleeve has the advantages of being simple in structure, low in cost, flexible and convenient to use, and good in fastness. The two-stage compound energy-containing bullet sleeve is capable of improving the fastness of a pre-posed compound sand-carrying perforating bullet, combining the pre-posed compound sand-carrying perforating bullet, compound gunpowder and the detonating cord together, and achieving eccentric fixation of the perforating bullet. Scientific and reasonable combination of the perforating bullet and the compound gunpowder can improve deep penetration of a perforator and strengthen subsequent effect of perforation.
Description
Technical field
The utility model is specifically related to a kind of twin-stage composite energy-containing bullet cover for perforating oil gas well.
Background technology
At present, be used for perforating oil gas well lined-cavity charge fixedly be to be withstood in the circular pipe type firing mount hole by the body male cone (strobilus masculinus), the perforating bullet other end compresses with firing mount; In perhaps perforating bullet was packed circular pipe type firing mount hole into, the perforating bullet other end compressed with detonating fuse.
The utility model content
The purpose of this utility model is to take full advantage of space in the perforating gun, perforating bullet, the preposition sand recombiner, compound gunpowder, detonating fuse taken are grouped together scientifically and rationally, make the perforating bullet permanent position depart from the center line of perforating gun, improve the perforating bullet height of burst, and make four fixations, reach and improve the effect that perforator was worn deeply, reduced the perforating bullet manufacturing cost and strengthens the follow-up effect of perforation
The utility model is achieved by the following technical solution:
It is a kind of twin-stage composite energy-containing bullet cover, the bullet cover that comprises hollow, bullet cover top is frustum section, the bottom is cylindrical portion, the frustum section upper end that it is characterized in that the bullet cover is provided with cylindrical positioning boss, positioning boss is provided with the detonating fuse gathering sill, is respectively equipped with compound gunpowder coyote hole outside the both sides, cylindrical portion top of bullet cover.
As a preferred version of the present utility model: be provided with two symmetrically arranged oblique claws outside the both sides, cylindrical portion lower end of bullet cover.
As another preferred version of the present utility model: be provided with claw in two symmetrically arranged elasticity in the both sides, cylindrical portion lower end of bullet cover.
Compound bullet cover of the present utility model is selected plastics or other metals, nonmetals, the frustum section upper end of bullet cover is provided with cylindrical positioning boss, establish the detonating fuse gathering sill on it, two oblique claws of both sides, cylindrical portion bottom peripheral hardware of bullet cover, inwall is established claw in two elasticity.The inner chamber of bullet cover cooperates with the perforating bullet profile, after perforating bullet is packed in the bullet cover, detonating fuse is pushed down on the perforating bullet top, recombiner is installed in lower end at the bullet cover, utilize the interior claw of elasticity to block recombiner both sides positioning table, compound gunpowder coyote hole is established respectively in the cylindrical portion outer surface of upper both sides of bullet cover, and the compound gunpowder of packing in two compound gunpowder coyote holes can use.
The utility model is not only applicable to common perforating bullet, is applicable to the preposition compound sand perforating bullet of taking yet, and the preposition compound sand perforating bullet of taking is made of the described preposition front end that the sand medicine box is fixedly mounted on deep penetrating charge of taking deep penetrating charge and the preposition sand medicine box of taking.
The utlity model has advantage simple in structure, that cost is low, flexible and convenient to use, fastness is good.Use the utility model can improve the preposition compound fastness of sand perforating bullet on perforator of taking, the preposition compound sand perforating bullet, compound gunpowder, detonating fuse taken is grouped together, realize that perforating bullet is eccentric fixing, perforating bullet and the scientific and reasonable combination of compound gunpowder improve perforator and wear dark and the follow-up effect of enhancing perforation.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is use view of the present utility model.
Shown in the figure: 1-detonating fuse gathering sill; The 2-positioning boss; 3-frustum section; The compound gunpowder coyote hole of 4-; The oblique claw of 5-; The 6-cylindrical portion; Claw in the 7-elasticity; The preposition compound sand perforating bullet of taking of 8-; The 9-detonating fuse; The compound gunpowder of 10-; The 11-recombiner.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1 and Figure 2: the bullet cover inner chamber of hollow and the preposition compound profile coupling of taking sand perforating bullet 8, frustum section 3 upper ends of bullet cover are provided with columniform positioning boss 2, positioning boss 2 is provided with detonating fuse gathering sill 1, be provided with two compound gunpowder coyote holes 4 outside the both sides, cylindrical portion 6 top of bullet cover, be provided with the oblique claw 5 of two symmetries outside the both sides, cylindrical portion 6 upper end of bullet cover, claw 7 in the company's of being provided with symmetrical elasticity in the both sides, cylindrical portion 6 upper end of bullet cover.
When the utility model uses, as shown in Figure 3: with preposition compound take sand perforating bullet 8 and pack in the bullet cover after, detonating fuse 9 is pushed down on preposition compound sand perforating bullet 8 tops of taking, recombiner 11 is installed in lower end at the bullet cover, utilize the interior claw 7 of two elasticity to block recombiner 11 both sides positioning tables, the compound gunpowder 10 of packing in two compound gunpowder coyote holes 4 can use.
The utility model is not limited to above embodiment, can also adopt common perforating bullet, the utility model can improve the fastness of perforating bullet on perforator, perforating bullet, compound gunpowder, detonating fuse are grouped together, realize that perforating bullet is eccentric fixing, perforating bullet and the scientific and reasonable combination of compound gunpowder improve perforator and wear dark and the follow-up effect of enhancing perforation.
