Abstract
The utility model relates to a new bullet for tri-cone shaped-charge liner is to solve the difficulty of batch production of large diameter deep penetration type bullet of shaped-charge liner due to complex of production procedure. The utility model is characterized in that the top of a shaped-charge liner (2) is an arch shape; the lateral wall of the shaped-charge liner (2) is three cone angle comprising different cones. The liner is characterized with large diameter and deep penetration and simple procedure.
Description
Technical field:
The utility model relates to positioner used in the oil exploration and development fields, belongs to a kind of novel third hand tap cavity liner perforating bullet.
Background technology:
The sleeve pipe inlet calibre of perforating bullet is two important performance indexes of perforating bullet with wearing deeply, also is the key factor that influences oil well productivity.Research points out that hole depth increases, the aperture increases, and capacity of oilwell enlarges markedly.The type perforating bullet aperture, large aperture of using in the present stage oil field is big but wear more shallowly deeply relatively, and that deep penetration type perforating bullet is worn is deep deeply, but bore is less relatively again.Once the cavity liner perforating bullet that had circular arc to combine with circular cone on producing reaching the deep penetrating effect in large aperture, but owing to the production technology more complicated of cavity liner, is difficult to produce in batches.
The utility model content:
In order to overcome existing big diameter and deep penetrating type cavity liner perforating bullet complex manufacturing, the deficiency that is difficult to produce in batches, the utility model provides a kind of novel third hand tap cavity liner perforating bullet, and this perforating bullet has large aperture, deep penetration and production technology characteristic of simple.
The technical solution of the utility model is: a kind of novel third hand tap cavity liner perforating bullet comprises shell case and cavity liner, is equipped with explosive between shell case and the cavity liner, and the top of cavity liner is circular-arc, and the sidewall of cavity liner is that three sections different taper seats of cone angle are formed by connecting.
Three sections taper seat cone angles of above-mentioned cavity liner are respectively first awl between 30 °～50 °, and second awl is between 50 °～70 °, and third hand tap is between 30 °～50 °.
The utlity model has following beneficial effect: owing to take such scheme, the sidewall of cavity liner is the linear pattern bus, is easy to processing, has simplified production technology, has reduced manufacturing cost, is fit to produce in batches; The angle of three cone angles of cavity liner reasonable in design, the energy-gathering jetting that utilizes the perforating bullet of this cavity liner to form is bigger at sleeve pipe upper shed bore, the perforation duct is darker, through the detection of industry authoritative department, reached desirable opening bore with wear dark.
Description of drawings:
Accompanying drawing 1 is a structure cutaway view of the present utility model.
1-shell case among the figure, 2-cavity liner, 3-explosive, 4-first awl, 5-second awl, 6-third hand tap.
The specific embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of novel third hand tap cavity liner perforating bullet comprises shell case 1 and cavity liner 2, is equipped with explosive 3 between shell case 1 and the cavity liner 2, and the top of cavity liner 2 is circular-arc, and the sidewall of cavity liner 2 is that three sections different taper seats of cone angle are formed by connecting.Three sections taper seat cone angles of cavity liner 2 are respectively first awl 4 between 30 °～50 °, and second awl 5 is between 50 °～70 °, and third hand tap 6 is between 30 °～50 °.
In the actual production,, be easy to processing, simplified production technology, reduced manufacturing cost, be fit to produce in batches because the sidewall of cavity liner is the linear pattern bus.The angle of three cone angles of cavity liner reasonable in design in addition, the energy-gathering jetting that utilizes the perforating bullet of this cavity liner to form is bigger at sleeve pipe upper shed bore, the perforation duct is darker, through the detection of industry authoritative department, reached desirable opening bore with wear dark.
Claims (2)
1, a kind of novel third hand tap cavity liner perforating bullet, comprise shell case (1) and cavity liner (2), be equipped with explosive (3) between shell case (1) and the cavity liner (2), it is characterized in that: the top of cavity liner (2) is circular-arc, and the sidewall of cavity liner (2) is that three sections different taper seats of cone angle are formed by connecting.
2, a kind of novel third hand tap cavity liner perforating bullet according to claim 1, it is characterized in that: three sections taper seat cone angles of cavity liner (2) are respectively first awl (4) between 30 °～50 °, second awl (5) is between 50 °～70 °, and third hand tap (6) is between 30 °～50 °.
