Abstract
The utility model relates to the oil field a kind of high burst hight light-duty perforator used for exploring, in perforation completion process.This perforator comprises main body, top connection and lower contact, and described main body, top connection and lower contact take the thick mode of pier to form the thick structure be integrated in intermediate thin two by Technology for Heating Processing, and the internal diameter of main body is greater than the internal diameter of top connection and lower contact.The light-duty perforator structure of this high burst hight is relatively simple, and the effective height of burst of perforating bullet dress rifle increases, and improve the perforating depth of perforating bullet in rock stratum, weight saving simultaneously, saves production cost.
Description
Technical field
The utility model relates to the oil field a kind of perforating appliances at underground blasting rock stratum and sleeve pipe used for exploring, in perforation completion process, the light-duty perforator of a kind of high burst hight specifically.
Background technology
The perforator that current domestic each elephant uses is outer blind hole perforating tool and inner blind hole perforator mostly, and Daqing oil field has started to use inner blind hole perforator in a large number.The height of burst of inner blind hole perforator is higher, mutually external blind hole perforating tool, and use the perforating bullet of same model, interior blind hole wears dark increasing, and effectively wear deeply to pursue, inner blind hole perforator is more general.But inner blind hole perforator difficulty of processing is large, blind hole in the processing of body of perforating gun inwall, its iron filings not easy to clean, burr around interior blind hole is difficult to remove, and is so just easy to cause the phenomenon scratching, even scrape disconnected detonating fuse, thus brings serious potential safety hazard to perforating job.
utility model content:
In order to solve the problem, the utility model provides a kind of high burst hight light-duty perforator.The light-duty perforator structure of this high burst hight is relatively simple, and the effective height of burst of perforating bullet dress rifle increases, and improve the perforating depth of perforating bullet in rock stratum, weight saving simultaneously, saves production cost.
The technical solution of the utility model is: the light-duty perforator of a kind of high burst hight, comprise main body, top connection and lower contact, described main body, top connection and lower contact take the thick mode of pier to form the thick structure be integrated in intermediate thin two by Technology for Heating Processing, and the internal diameter of main body is greater than the internal diameter of top connection and lower contact.
Described top connection and lower contact structure identical, all with sealing surface, connecting thread and seam.
The beneficial effects of the utility model are: 1, the internal diameter of this perforator burst region and 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 improves the perforating depth of perforating bullet in rock stratum; Meanwhile, there is not the problem of blind hole to bit rate during perforation, improve perforating quality.2, this perforator when external diameter is measure-alike effective fragmentation part and rifle body bulkhead thin, alleviate weight, thus alleviate the labour intensity of workman, and saved cost of production.
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.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1, the light-duty perforator of this high burst hight, comprise main body 2, top connection 1 and lower contact 3, described main body 2, top connection 1 and lower contact 3 take the thick mode of pier to form the thick structure be integrated in intermediate thin two by Technology for Heating Processing, the internal diameter of main body 2 is greater than the internal diameter of top connection 1 and lower contact 3, form the structure that intermediate thin two is thick, eliminate the current problem having blind hole perforating tool to there is phase angle.
Described top connection 1 and lower contact 3 structure identical, all with sealing surface 4, connecting thread 5, seam 6, make that the existing connecting elements of the light-duty perforator of this high burst hight and other is convenient to be connected.
In such scheme, 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, perforating bullet gun setting and burst height increases, and improves the perforating depth of perforating bullet in rock stratum; Meanwhile, owing to there is no blind hole, there is not the problem of blind hole to bit rate during perforation, improve perforating quality and reliability; In addition, the existing perforating gun of weight ratio of this perforator is lightweight, because this reducing perforating gun manufacturing cost, alleviates labour intensity when perforating gun uses.
