Abstract

The utility model relates to a light deep penetration perforator used in the exploration and perforation completion processes of oil fields. The perforator comprises a main body, an upper joint and a lower joint, wherein the main body, the upper joint and the lower joint are fixed into a whole, and the inner diameter of the main body is larger than the inner diameters of the upper joint and the lower joint. The portable deep penetration perforator has the advantages that the structure is relatively simple, the effective explosive height of a perforating bullet loading gun is increased, the perforating depth of perforating bullets on rock stratums is improved, meanwhile, the weight is reduced, and the production cost is saved.

Description

The lightweight deep penetration perforator
Technical field
The utility model relates to oil field for exploration, perforation completion process a kind of equipment of the perforation at underground blasting rock stratum and sleeve pipe used, a kind of lightweight deep penetration perforator specifically.
Background technology
The perforator that at present domestic each elephant is used is outer blind hole perforating tool and inner blind hole perforator mostly, and Daqing oil field has started to use in a large number inner blind hole perforator.The height of burst of inner blind hole perforator is higher, and external blind hole perforating tool is mutually used the perforating bullet of same model, and interior blind hole is worn dark increasing, in order to pursue, effectively wears deeply, and inner blind hole perforator is more general.But the inner blind hole perforator difficulty of processing is large, from the interior blind hole of body of perforating gun inwall processing, its iron filings are easy to clean not, burr around interior blind hole is difficult to remove, and so just is easy to cause the phenomenon that scratches, even scrapes disconnected detonating fuse, thereby brings serious potential safety hazard to perforating job.
the utility model content:
In order to address the above problem, the utility model provides a kind of lightweight deep penetration perforator.This lightweight deep penetration perforator structure is relatively simple, and the effective height of burst of perforating bullet dress rifle increases, and has improved the perforating depth of perforating bullet in rock stratum, and weight saving simultaneously, save production cost.
The technical solution of the utility model is: a kind of lightweight deep penetration perforator, comprise main body, top connection and lower contact, and described main body, top connection and lower contact are fixed as one, and the internal diameter of main body is greater than the internal diameter of top connection and lower contact.
Above-mentioned top connection and lower contact structure are identical, all with sealing surface, connecting thread seam.
The beneficial effects of the utility model are: the internal diameter that 1, this perforator burst region is main body is greater than existing same model perforator, and because body of a gun inner cavity size strengthens, the effective height of burst of perforating bullet dress rifle increases, and has improved the perforating depth of perforating bullet in rock stratum; Simultaneously, there do not is the problem of blind hole to bit rate during perforation, improved perforating quality.2, this perforator, in the situation that the measure-alike effective fragmentation part of external diameter and rifle body bulkhead are thin, have alleviated weight, thereby has alleviated workman's labour intensity, and saved cost of production.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
1-top connection in figure, 2-main body, 3-lower contact, 4-sealing surface, 5-connecting thread, 6-seam, 7-weld bond.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, this lightweight deep penetration perforator, comprise main body 2, top connection 1 and lower contact 3, described main body 2, top connection 1 and lower contact 3 threes are integrated by being welded and fixed, as shown in Figure 1, in figure, 7 is weld bond, and the internal diameter of main body 2 is greater than the internal diameter of top connection 1 and lower contact 3, form the thick structure in intermediate thin two, eliminated the current problem that has blind hole perforating tool to have phase angle.
Described top connection 1 and lower contact 3 structures are identical, all with sealing surface 4, connecting thread 5 seams 6, the existing connecting elements of this lightweight deep penetration perforator and other conveniently are connected.
In such scheme, the perforator external diameter is identical with existing perforating gun external diameter, and convenient and existing equipment supports the use, and its internal diameter is greater than existing perforating gun internal diameter, because body of a gun inner cavity size strengthens, the perforating bullet gun setting and burst height increases, and has improved the perforating depth of perforating bullet in rock stratum; Simultaneously, owing to there is no blind hole, there do not is the problem of blind hole to bit rate during perforation, improved perforating quality and reliability; In addition, the existing perforating gun of the weight ratio of this perforator is lightweight, has therefore reduced the perforating gun manufacturing cost, has alleviated labour intensity when perforating gun uses.
