Abstract
The utility model discloses a single bore hole sand blower, which comprises a main body, an aperture gradually reduced through hole arranged at the center of the main body form up to down. The utility model is characterized in that a spray nozzle made of high strength alloy is fixed at the outlet, due to the spray nozzle made of high strength alloy arranged at the outlet, the utility model can lighten the abrasion of sand fracturing liquid to the spray nozzle, thereby to improve the service life of the single bore hole sand blower.
Description
Technical field
The utility model relates to the used instrument of a kind of oil field oil recovery, the single hole sandblaster that uses in particularly a kind of oilfield oil well pressing crack construction.
Background technology
Existing single hole sandblaster is offered the through hole of an aperture convergent from top to bottom in main body, this single hole sandblaster is installed on the fracturing string bottom, of the fracturing fluid discharge capacity is very big, when fracturing fluid passes through this single hole sandblaster, because of the aperture of its lower end little than top, produce certain chock pressure difference herein, and be arranged in the fracturing string and the packer that is positioned at this single hole sandblaster top relies on this chock pressure difference sealing oil sets annular space.Because of the material in existing single hole sandblaster exit is the same with main body, not wear-resisting for common carbon steel or common alloy steel, cause dashing and very easily wearing and tearing under grinding containing the of the fracturing fluid injection of sand.
Summary of the invention
The purpose of this utility model is to have the not wear-resisting problem in single hole sandblaster exit now in order to solve, and a kind of single hole sandblaster above-mentioned shortcoming, that have wear-resisting nozzle that overcomes is provided.
The utility model includes a main body, offers the through hole of an aperture convergent in the middle of this main body from top to bottom, it is characterized in that, is fixed with a nozzle of being made by high-strength alloy in the exit.
The utility model is owing to be provided with the nozzle that high-strength alloy is made in the exit, can alleviate to contain the sand fracturing fluid to nozzle abrasion, thereby improve the application life of single hole sandblaster.
Description of drawings
Fig. 1 is the half section schematic diagram of the utility model embodiment.
The specific embodiment
See also shown in Figure 1, the utility model embodiment includes a main body 1, offer the through hole 3 of an aperture convergent in the middle of this main body 1 from top to bottom, it is characterized in that, be fixed with a nozzle 2 of making by high-strength alloy in the exit, in this embodiment, used high-strength alloy is a tungsten-cobalt hard alloy.The fixed form of nozzle 2 can be welding, also can be that screw is fixed, or other fixed forms.
The utility model is owing to be provided with the nozzle 2 that high-strength alloy is made in the exit, can alleviate to contain the wearing and tearing of sand fracturing fluid to nozzle 2, thereby improve the application life of single hole sandblaster.
Claims (2)
