Abstract
The utility model relates to a composite rack of composite perforator for oil gas wells, which comprises a tubular firing mount and a powder column sleeve. The powder column sleeve is sheathed in the tubular firing mount, and a gunpowder propellant is arranged in the powder column sleeve, and the powder column sleeve is provided with a columnar hole and a shield key. The shield key can prevent a perforating bullet keeping certain bursting height with the perforator, and enhances the perforating depth of the perforating bullet. The product is easy in use, and the perforating and making seam operation can be completed at one time.
Description
The utility model belongs to design and the manufacturing technology field of oil gas well with compound of composite perforator.
Compound of employed composite perforator in the production operation of oil gas well at present, the mode that mostly adopts the gunpowder of in the iron firing mount, directly packing into to detonate, execute-in-place uses, and both has been not easy to produce in batches, is not easy to again use.Also have plenty of the mode that adopts detonating fuse segmentation propagation of explosion, i.e. pack into perforating bullet and detonating fuse of segmentation in perforator, because detonating fuse is the segmentation form, place blocking-up just can not all be detonated, thus influence blast perforating effect.Therefore, also there be not the product identical to use aborning at present with the utility model.
The purpose of this utility model provides compound of a kind of composite perforator that has a powder column cover, to solve the particular problem that the said goods occurs easily.
Structure of the present utility model as shown in drawings; Be made of tubulose firing mount and powder column cover, the powder column cover is housed in the tubulose firing mount, the power propellant of some is housed in the coyote hole of powder column cover two ends, the powder column cover constitutes powder column after loading onto propellant.Put at powder column and to have cylinder hole.There is block key front portion at cylinder hole, in the cylinder hole of powder column cover lined-cavity charge is housed, and lined-cavity charge is blocked by the block key on the cylinder hole, makes the perforating bullet fixed-site, can not move.Have detonating fuse in tubulose firing mount outside.Using method of the present utility model is that this device is packed in the perforating gun, sends into precalculated position in the well with the oil well cable, is ignited by electric cap, realizes that perforation makes the purpose of seam.
The utility model is simple in structure, and is reasonable in design, can reach perforation aborning and make the seam operation and once finish, and it is reliable to be easy to use.Owing to have block key on cylinder hole, block key prevents that perforating bullet from moving, and makes the body of a gun inwall of perforating bullet and perforator keep certain height of burst, to improve the perforating depth of perforating bullet.

Tubulose firing mount of the present utility model is a metal system, and the powder column cover is plastics system, and its detonating fuse is the general equipment of explosion, and its enforcement relates to metal and plastic processing specialty, with reference to this manual and accompanying drawing, comes production and processing by its known technology, can reproduce.The utility model is real by following technical solution; Powder column cover (4) is housed in the tubulose firing mount (1).The tubulose firing mount has side opening on the half-twist position.Powder column cover also is a tubular body, has the cylinder hole (6) with axis normal in the middle, and the front end in hole has the block key (7) of two symmetries.The two ends of powder column cover have coyote hole, the power propellant of interior dress some (5).The outer internal diameter that gently is slightly less than the tubulose firing mount of powder column cover makes its tubulose firing mount of packing into smoothly.The cylinder hole of powder column cover and the side opening of firing mount match.Lined-cavity charge (3) is housed in the cylinder hole.The outside of tubulose firing mount has detonating fuse (2).The detonating fuse helical form is on the tubulose firing mount.The afterbody of lined-cavity charge has the cap of igniting that detonates, and there is a metal silk pressing on the cap next door of igniting, and detonating fuse is fixed on detonating of perforating bullet by silk pressing and ignites on the cap.
Claims (1)
- Compound of oil gas well composite perforator is made of tubulose firing mount (1) and powder column cover (4), it is characterized in that powder column puts to have cylinder hole (6), has block key (7) in the front portion of cylinder hole.
