Abstract

The utility model provides a high pressure nozzle is used in oil field, include connector, shell, turn round that the connector is rear end face open -ended cavity structure, the shell comprises communicate with each other continuous hollow cylinder and hollow hemispheroid, and hollow cylinder passes through threaded connecting sleeve and establishes on the outer wall of connector, and hollow hemispheroid ball backs down and is equipped with the delivery port, it sets up in the bottom of connector to turn round to rotate, and the impact orifice has evenly been seted up to the bottom of connector, still include around the delivery port evenly set up in hollow hemispheroid on the arc surface with the briquetting. Adding setting up of briquetting and making the liquid fluid pressure when flowing through the delivery port after rotatory rise, highly pressurised liquid and increased highly pressurised liquid's spray regime has effectively atomized.

Description

A kind of oil field high-pressure nozzle
Technical field
The utility model relates to a kind of high-pressure nozzle, particularly relates to a kind of oil field high-pressure nozzle.
Background technology
At present, adopt high-pressure hydraulic to spray radial pore-forming increase yield in oil field and become a kind of general technology.Mainly carry shower nozzle by high-pressure hose to improve object oil reservoir hole through row jetting and ooze parameter, improve oil well output with this.High-pressure hydraulic sprays radial hole creating technology and originates from jetting flushing oil pipe drill rod, and afterwards by improving shower nozzle and relevant auxiliary equipment, intensified pressure sprays producing horizon position, develops into a kind of oilfield stimulation technology of high-efficiency and economic gradually.But the existing nozzle structure for oil field is comparatively complicated and jeting effect is also poor.
Utility model content
Complicated for solving nozzle structure, the defects such as jeting effect difference, the utility model spy provides a kind of oil field high-pressure nozzle.
The technical solution of the utility model is as follows:
A kind of oil field high-pressure nozzle, comprise connector, shell, rotary head, connector is the cavity structure of rear end face opening, shell is made up of communicate connected hollow cylinder and hollow hemisphere, hollow cylinder is threaded connection and is set on the outer wall of connector, and hollow hemisphere ball backs down and is provided with delivery port; The bottom being arranged on connector is rotated in rotary head, and the bottom even of connector offers impact spray orifice; Also comprise the pressurizing block be evenly arranged on around the mouth of a river on hollow hemisphere inner arc surface.
Further, described pressurizing block is made up of elastomeric material.
Further, described impact spray orifice is inclined at bottom connector, and described rotary head sidewall evenly offers groove, and groove rotation direction is contrary with the direction that impact spray orifice is obliquely installed.
Further, described connector front end face offers circular groove, also comprises the steel ball be arranged in circular groove, and rotary head and connector are rotationally connected by steel ball.
Advantageous Effects of the present utility model is as follows:
1, pressurizing block be arranged so that postrotational liquid fluid pressure when flowing through delivery port raises, be effectively atomized highly pressurised liquid and added the spray regime of highly pressurised liquid.
2, pressurizing block is made up of elastomeric material, effectively improves pressure effect.
3, impacting spray orifice to be obliquely installed and groove rotation direction is contrary with impacting the direction that is obliquely installed of spray orifice, making to produce circumferential active force when can be impacted the surface of rotary head by the liquid of impact spray orifice, enabling rotary head High Rotation Speed.
4, steel ball frictional force is little, and rotary head and connector are rotated flexibly.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of oil field high-pressure nozzle;
Component title wherein corresponding to Reference numeral is as follows: 1-connector, 2-shell, 3-rotary head, 4-hollow cylinder, 5-hollow hemisphere, 6-delivery port, and 7-impacts spray orifice, 8-pressurizing block, 9-groove, 10-steel ball.
Specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail, but embodiment of the present utility model is not limited to this.
Embodiment 1
As shown in Figure 1, a kind of oil field high-pressure nozzle, comprise connector 1, shell 2, rotary head 3, connector 1 is the cavity structure of rear end face opening, shell 2 is made up of the hollow cylinder 4 communicating connected and hollow hemisphere 5, hollow cylinder 4 be threaded connection be set in connector 1 outer wall on, hollow hemisphere 5 ball backs down and is provided with delivery port 6; The bottom being arranged on connector 1 is rotated in rotary head 3, and the bottom even of connector 1 offers and impacts spray orifice 7; Also comprise the pressurizing block 8 be evenly arranged on around the mouth of a river 6 on hollow hemisphere 5 inner arc surface.
In the present embodiment, pressure duct is fixed by the opening of connector 1 rear end face and connector 1, the highly pressurised liquid of pressure duct input enters in the cavity of shell 2 by impacting spray orifice 7, and rotary head 3 is impacted, rotary head 3 rotates under impact at a high speed, through postrotational liquid stream through delivery port 6 time will extrude pressurizing block 8, again will be raised by the fluid pressure of pressurizing block 8 after extruding, be effectively atomized highly pressurised liquid and added the spray regime of highly pressurised liquid.
Embodiment 2
The present embodiment is on the basis of embodiment 1, and described pressurizing block 8 is made up of elastomeric material.
Pressurizing block 8 is made up of elastomeric material, effectively improves pressure effect.
Embodiment 3
The present embodiment is on the basis of embodiment 1 or embodiment 2, and described impact spray orifice 7 is inclined at bottom connector 1, and described rotary head 3 sidewall evenly offers groove 9, and groove 9 rotation direction is contrary with impacting the direction that spray orifice 7 is obliquely installed.
Impacting spray orifice 7 to be obliquely installed and groove 9 rotation direction is contrary with impacting the direction that is obliquely installed of spray orifice 7, making to produce circumferential active force when can be impacted the surface of rotary head 3 by the liquid of impact spray orifice 7, make rotary head 3 can High Rotation Speed.
Embodiment 4
The present embodiment is on the basis of embodiment 1 or embodiment 2 or embodiment 3, and described connector 1 front end face offers circular groove, also comprises the steel ball 10 be arranged in circular groove, and rotary head 3 and connector 1 are rotationally connected by steel ball 10.
In the present embodiment, steel ball 10 frictional force is little, and rotary head 3 and connector 1 are rotated flexibly.
As mentioned above, the utility model can be realized preferably.
