Abstract

The utility model relates to a petroleum perforating bullet transmitting and clamping device, comprising an upper cap, a lower supporter and a guard strip. The upper cap and the lower supporter are in threaded connection, on one hand, the loading and taking out of the perforating bullet are convenient, on the other hand, the upper cap can be matched with a lug boss on the lower supporter, so the perforating bullet arrange and form device can be tightly clamped, the perforating bullet is unmovable with accurate position, and the perforating concentration can be increased by 5%-10%. A detonating fuse clamping head can be directly arranged on the upper cap for convenient and firm installation of the detonating fuse, and the utility model can also be used as a transmit protective case matching with the guard strip.

Description

Cue torr

The utility model belongs to the delivery clamping device of the oil ore deposit oil recovery producer goods, particularly well perforating bullet.

In the process of oil production, carry out perforation to cased stratum well.Oil bearing bed is penetrated the hole of wearing some certain depths, and oil is just therefrom gushed out, people just adopt oil.Perforation all adopts special-purpose perforation bomb at present.The clamping device of this bomb promptly is the bullet holder.Existing bullet holder mainly contains two kinds of forms.A kind ofly be made up of arc steel band and steel wire clamp, when fixing perforating bullet with it, the free gap of perforating bullet is big, and is difficult for centering, and detonating fuse is fixed the not firm miso-fire that is prone to, and perforating depth is dwindled.Another kind is the bullet-headed object with injection molding, make the plastics hook on the microcephaly, be used for hanging over perforating bullet form to be arranged, the other end make garden week interior receipts collude shape, perforating bullet is therefrom filled in by elasticity, drawn in then perforating bullet is stuck in wherein.This a kind of still unresolved centering property in back, and pack into and take out difficulty easily.

The purpose of this utility model provides that a kind of that perforating bullet is packed into is convenient to remove, and fixed-site is accurately firm, and detonating fuse is installed reliably bullet holder easily, and the transportation protection of perforating bullet can be provided.

The utility model is realized as follows, the subiculum that the garden is tubular, and an end has the edge of inside gathering 90 degree, and the pin thread on the external surface that begins from another termination ends near the annular boss.Combine into loam cake by umbrella shape part with the garden barrel portion, umbrella shape part central authorities are porose, and respectively there is a detonating fuse dop both sides, hole, the negative thread that garden barrel portion inwall has the pin thread with subiculum to be complementary.The bluff piece of thin garden sheet shape covers on the edge of inwardly drawing in subiculum and can not drop out.

The utility model has following advantage.Being threaded between subiculum and the loam cake makes to shoot convenient firmly that when screw thread screwed, the linkage that boss on the subiculum and loam cake are arranged usefulness to the formation perforating bullet firmly clamped, non-loosening and accurate positioning, thus improved the perforating quality and the degree of depth.Bluff piece separates the body and the external world, shields when transportation.Detonating fuse is reliable convenient by dress.

Represented to drawings clear embodiment of the present utility model.Among Fig. 1, clip between loam cake (1) and the subiculum (2) and arrange linkage (3), subiculum (2) lining is bluff piece (4).

Claims

1, a kind of bullet holder, it is characterized in that this device by:

A. the oriented invagination of an end is fallen the edges of 90 degree, the pin thread that begins from the other end on the outer surface, and pin thread ends at the tubular subiculum in the garden of annular boss (2);

B. a part is a canopy shape for the tubular another part in garden, the negative thread that garden barrel portion inwall has the pin thread with subiculum (2) to be complementary, and canopy shape part central authorities have the hole, and respectively there is the loam cake (1) of and relative thirty years of age detonating fuse dop the both sides in hole;

C. can be loaded on the unlikely again bluff piece that therefrom drops out (4) in the subiculum (2), the common composition.
