Description
【Technical field】
The invention belongs to technical field, and in particular to a kind of single-blade hydraulic ejector, more particularly, to a kind of suitable profit
Relation complexity is, it is necessary to make the cracky hydraulic ejector of single-blade.
【Background technology】
For conventional reservoir, hydraulic jet perforation aperture is big, perforation depth, and the intensity of rebuilding is big.But, some reservoir oils
Water relation is complicated, also less clear to waterline understanding, in order to waterline alters logical, aqueous rising after preventing transformation, is needed during fracturing reform
Magnitude control is wanted, double-vane crack is obtained after the injection of conventional hydraulic injector, be distributed in pit shaft both sides, seam length is larger, may draw
Play pressure break water outlet, transformation failure.
【The content of the invention】
The technical problems to be solved by the invention are for above-mentioned deficiency of the prior art, there is provided a kind of single-blade waterpower
Injector, can only produce single-blade crack in pressure break, and stimulation work is carried out to oil water relation complexity oil reservoir.
The present invention uses following technical scheme：
A kind of single-blade hydraulic ejector, including ejector body, and it is arranged on the top connection of the body upper and lower ends
And lower contact, multiple pressure caps are arranged at intervals with the body, it is provided with nozzle in each described pressure cap, the nozzle is towards institute
The outside for stating body is set.
Further, the central axis of each described pressure cap and the body is at an angle of 90.
Further, multiple pressure caps are arranged on the side of the body.
Further, the pressure cap passes through screwed connection with the body.
Further, the pressure cap at least includes three.
Further, multiple nozzles are set point-blank, and the straight line is parallel with the axis of the body.
Further, all nozzles on the body form an injection plane, and with the body on the same plane.
Compared with prior art, the present invention at least has the advantages that：
When a kind of single-blade hydraulic ejector of the present invention is applied to old filed repetition transformation, according to remaining oil distribution situation and oil
Well yield potential determines fracturing technology, and interval setting multiple pressure cap, sets nozzle on body in each pressure cap, carries out profit pass
It is the complicated small-scale fracturing work of reservoir, injector can be rotated by above carrying fracturing string, producing two has certain angle
And the independent new crack of single-blade.
Further, there is 90 degree of angle between pressure cap and the central shaft of body, by one direction perforation, single-blade is made
Crack, implements perforation stimulation work, compared with conventional hydraulic injector, reduces oil well water breakthrough risk after pressure break.
Further, pressure cap is arranged on the side of body, and nozzle is arranged on side and can form same plane with body.
Further, all nozzles on body form an injection plane, and are so penetrated in approximately the same plane with body
Kong Hou, perforation distribution can carry out perforation, so that more targeted in the same side of body according in the side of remaining oil distribution
Ground Remaining Oil.
In sum, emitter construction of the present invention is simple, safe, and by optimizing injector configuration, jet size can be with
Realize small-scale single hop perforation, it is also possible to realize small-scale multistage transformation with packer connection, can solve the problem that old filed profit is closed
It is complicated reservoir, scale is bigger than normal when directional well is transformed, and easily causes the problem of water breakthrough, the problems such as cause pressure break to fail, is applicable
Scope is wide.
Below by drawings and Examples, technical scheme is described in further detail.
【Brief description of the drawings】
Fig. 1 is schematic structural view of the invention.
Wherein：1. top connection；2. body；3. nozzle；4. pressure cap；5. lower contact.
【Specific embodiment】
In the description of the invention, it is necessary to illustrate, unless otherwise clearly defined and limited, term " installation ", " phase
Company ", " connection " should be interpreted broadly, for example, it may be being fixedly connected, or being detachably connected, or be integrally connected；Can
Being to mechanically connect, or electrically connect；Can be joined directly together, it is also possible to be indirectly connected to by intermediary, Ke Yishi
Two connections of element internal.For the ordinary skill in the art, with concrete condition above-mentioned term can be understood at this
Concrete meaning in invention.
When the present invention is applied to old filed repetition transformation, part reservoir oil water relation is complicated, to its waterline understanding also less
Clearly, in order to prevent waterline after transforming from altering logical, aqueous rising, the construction of magnitude control is needed during fracturing reform.According to old filed
Reservoir geology test data, can draw remaining oil distribution situation and oil well production increasing potentiality, determine fracturing technology, and the present invention is according to upper
The situation of stating determines injector nozzle number, forms single-blade hydraulic ejector.
Refer to shown in Fig. 1, a kind of single-blade hydraulic ejector of the invention, it includes top connection 1, ejector body 2, spray
Mouth pressure cap 4, nozzle 3 and lower contact 5；The top connection 1 and lower contact 5 are connected to the upper end and lower end of the body 2, institute
State nozzle 3 to be fixed in the nozzle pressure cap 4, the nozzle pressure cap 4 is fixed on the side of the ejector body 2, and described
Nozzle 3 is set towards the outside of the ejector body 2；Meanwhile, between the central shaft of nozzle pressure cap 4 and the ejector body 2
Tool
Enter under injector to specified stratum, the injection plane of formation one of all nozzles 3 in the ejector body 2,
The injection plane is with the ejector body 2 on the same plane.Injector is rotated by well head, changes injection direction, not
Short seam is made on equidirectional.
Further, single-blade hydraulic ejector as described above, preferably, each nozzle 3 is distributed in straight line
On, the straight line parallel is in the axis of the ejector body 2；In actual applications according to the length of ejector body 2, nozzle is disposed
Number.
Specific work process is as follows：
First, according to remaining oil test data, perforating site is determined；
Secondly, according to required seam calculated pump rate long,
Then, it is determined that enter position under going out single-blade hydraulic ejector top nozzle number, size and injector,
Finally, injector is connected on tubing string, acts former well casing post, carry out through wash well operations, lower instrument oil pipe is carried out
Pressure testing, under enter single-blade hydraulic ejector, carry out hydraulic perforating operation.
The present invention solves the complicated reservoir of old filed oil water relation, and scale is bigger than normal when directional well is transformed, and easily causes water
The problem altered.Small-scale single hop perforation can be realized, it is also possible to realize that small-scale multistage is transformed with packer connection.
