The hydraulic sand blaster comprises a hydraulic sand blaster body, a nozzle and an internal suction type guide pipe, wherein the hydraulic sand blaster body, the nozzle and the internal suction type guide pipe are provided with medium channels which are communicated with each other, the internal suction type guide pipe is arranged at the inlet end of the nozzle, so that the speed variation of sand carrying liquid during steering can be effectively reduced, meanwhile, vortex formed during steering of the sand carrying liquid is controlled in the internal suction type guide pipe, and the inlet end part of the nozzle is provided with a mounting part.
Description
Technical field
The present invention relates to the anti-interior erosion hydraulic blast of one kind, belong to petroleum-gas fiedl hydraulic sand blasting fracturing technique field.
Background technology
The hydraulic sand blasting staged fracturing technology jet application technology new as one, changes in low permeability oil and gas field horizontal well
It is widely applied in making.The key tool of the technology is hydraulic blast, the high-speed jet formed by hydraulic blast
Multiple ducts are penetrated into open on stratum and form sustained firing after some microcracks, make ground by pressurized effect caused by high-velocity fluid
Layer crack initiation simultaneously forms crack, and oil pipe load fluid is pumped into crack by hydraulic blast injection, and annular space pumping liquid carries out pressure benefit
Repay, complete reservoir reconstruction.Have the characteristics that small construction risk, efficiency high, cost are low, available for a variety of completions such as bore hole, sleeve pipe
Mode, one-trip string can complete multistage pressing crack construction.
At present, hydraulic blast shows antiwear property deficiency in use, fails the problem of fast, causes to construct
Efficiency is low, it is impossible to meets the needs of efficiency of construction is improved at scene.Research shows that load fluid is spray to the inter deterioration of injector
The main reason for emitter fails, flow direction when load fluid enters nozzle in injector need to change, entered in nozzle
Mouth end nearby produces vortex, and load fluid " can draw " hole, nozzle along erosion direction in the presence of vortex in ejector body
Neighbouring injector wall more and more thinner, until penetrating injector wall, cause injector failure.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of anti-interior erosion hydraulic blast.
The technical problems to be solved by the invention are the problem of internal face erosion are serious near hydraulic blast nozzle.
In order to solve the above-mentioned technical problem, the present invention provides one kind anti-interior erosion hydraulic blast, including ejector body,
Nozzle and internal-suction type guide pipe, the sanding machine body, nozzle and internal-suction type guide pipe have interconnected medium channel, institute
State the arrival end installation internal-suction type guide pipe of nozzle.
The inlet end portion of the nozzle is provided with installing component.
Beneficial effects of the present invention are as follows:
The present invention installs internal-suction type guide pipe in the arrival end of nozzle, can effectively reduce speed when load fluid turns to and dash forward
Variable, while the vortex formed when load fluid is turned to is controlled in internal-suction type guide pipe, avoids ejector body from being taken sand
The injury of liquid evorsion.The present invention can effectively reduce sanding machine wound of the evorsion to ejector body in the course of the work
Evil, the service life of sanding machine is improved, reduce because making a trip number caused by injector failure, improve efficiency of construction, reduce
Construction cost.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, by referring to following detailed description, can more completely more fully understand the present invention with
And easily learn many of which with the advantages of, but accompanying drawing described herein be used for a further understanding of the present invention is provided,
The part of the present invention is formed, schematic description and description of the invention is used to explain the present invention, do not formed to this hair
Bright improper restriction, such as figure are wherein:
Fig. 1 is the structural representation of the present invention.
The present invention is further described with reference to the accompanying drawings and examples.
Embodiment
Obviously, those skilled in the art belong to the guarantor of the present invention based on many modifications and variations that spirit of the invention is done
Protect scope.
Embodiment 1:In figure:1st, sanding machine body;2nd, nozzle pressure cap;3rd, nozzle;4th, internal-suction type guide pipe.
As shown in figure 1, the anti-interior erosion hydraulic blast of the present invention, mainly includes hydraulic blast body 1, the and of nozzle 3
Internal-suction type guide pipe 4, wherein hydraulic blast body 1, nozzle 3 and internal-suction type guide pipe 4 have interconnected medium channel,
The present invention's is particular in that:The arrival end installation internal-suction type guide pipe 4 of nozzle 3, when can effectively reduce load fluid steering
Velocity jump amount, while the vortex formed when load fluid is turned to is controlled in internal-suction type guide pipe, so as to reduce waterpower spray
Injury of the evorsion to ejector body in the course of the work of sand device, the service life of sanding machine is improved, reduced because injection
Make a trip number caused by device failure, improves efficiency of construction, reduces construction cost.
The invention discloses one kind to prevent interior erosion hydraulic blast, including sanding machine body, nozzle and internal-suction type guide pipe,
The arrival end installation internal-suction type guide pipe of the nozzle, the present invention increase internal-suction type guide pipe, the nozzle before nozzle entrance
Increase internal-suction type guide pipe before entrance, can effectively reduce velocity jump amount when load fluid turns to, while load fluid is turned to
When the vortex that is formed control in internal-suction type guide pipe, the present invention can reduce sanding machine in the course of the work evorsion to spray
The injury of emitter inside body, the service life of sanding machine is improved, reduce because making a trip number caused by injector failure, carry
High efficiency of construction, reduce construction cost.
Erosion hydraulic blast in one kind is anti-, including sanding machine body, nozzle and internal-suction type guide pipe, the sanding machine sheet
Body, nozzle and internal-suction type guide pipe have interconnected medium channel, it is characterised in that:In the arrival end installation of the nozzle
Suction guide pipe.The inlet end portion of the nozzle is equipped with installing component.
As described above, embodiments of the invention are explained, as long as but essentially without this hair of disengaging
Bright inventive point and effect can have many deformations, and this will be readily apparent to persons skilled in the art.Therefore, this
The variation of sample is also integrally incorporated within protection scope of the present invention.
