Abstract
The utility model relates to a nozzle for a deep penetration hydraulic perforator for oil wells. A front-cutoff conical surface with a conical tip angle of 90 DEG is arranged on the periphery of a front end plane, and a plurality of jetting holes which are communicated with an inner cavity are vertically and uniformly distributed on the front-cutoff conical surface. Accordingly, holes of bigger diameters can be punched, and the cutting efficiency can be improved.
Description
The utility model relates to a kind of nozzle tip of oil well deep penetration hydraulic perforating machine.
What adopt in the existing oil well at present, is with center of orifices (single hole) formula nozzle tip, because it is big inadequately to dash the channel diameter that penetrates, so in deep-well, can not produce enough cutting powers.
In view of this, the purpose of this utility model provides a kind of multiport nozzle head of deep penetration hydraulic perforating machine, except that keeping center of orifices, also offers uniform a plurality of spray orifice on the inverted cone surface that with the center of orifices axis is the center, improves the ability of impinge upon earth strata rock.
The purpose of this utility model is achieved in that a kind of porous group formula nozzle tip of deep penetration hydraulic perforating machine comprises supporting surface, inner chamber and preceding Transverse plane, wherein before hold level with both hands and offer a center of orifices, it is characterized in that: at preceding Transverse plane periphery cone-apex angle being set is 80 °-100 ° preceding truncated cone face, and this preceding truncated cone face is provided with the spray orifice of vertical uniform several communication with cavity.
Described spray orifice is 6.
The circular cone drift angle of truncated cone face is 90 ° before described.
Owing to adopt such scheme: can go out larger-diameter hole, and improve cutting effect.
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 the utility model exemplary embodiments cross-sectional schematic.
Among the figure: Transverse plane, 31 center of orifices, 4 preceding truncated cone faces, 41 spray orifices before 1 supporting surface, 2 inner chambers, 3.
Present embodiment is to be made of supporting surface 1, inner chamber 2, preceding Transverse plane 3 and preceding truncated cone face 4, as shown in Figure 1, and wherein:
Supporting surface 1 is the supporting surface that connects with flexible pipe with the nozzle body one, belongs to prior art.
Before Transverse plane 3 be nozzle tip foremost and perpendicular to the center line of supporting surface 1, on this preceding Transverse plane 3, be provided with the center of orifices 31 of a communication with cavity 2, belong to prior art.
Before truncated cone face 4 be to form the about 90 ° conical surfaces (be cone-apex angle be 80 °-100 °) adjacent with preceding Transverse plane 3 with the center line of supporting surface 1, the spray orifice 41 of uniform several communication with cavity 2 perpendicular to conical surface on this preceding truncated cone face 4, make the press waters in the inner chamber 2 can be by spraying into about 45 ° of directions with center line, formation produces shearing force to formation rock, not only enlarge the aperture of going out passage, and rock is subjected to also the easiest peeling off of 45 ° of direction shearing forces, thereby also improved the spray cutting power, promptly under the flow and pressure of same water, present embodiment has bigger cutting power than existing single spray orifice.
