Background technology
In oil gas proved reserves in recent years, the hyposmosis reserves proportion rate of climb is increasing year by year.Low Permeability Oil/gas
Tibetan permeability, porosity are low, and anisotropism is strong, and most Oil/gas Wells must implement Hydro Fracturing Stimulation Treatment rear and see production capacity, pressure
It is increasingly apparent to split effect of the yield-increasing technology in Low permeable oil and gas reservoirs exploitation.
Since nineteen forty-seven U.S. Kansas Houghton oil fields successfully carry out the first in the world mouth well crushing test, pass through
The development of more than 60 years, fracturing technique are all rapidly progressed from technique, fracturing material to fracturing unit, it has also become improve individual well
Yield and the important means for improving oil-gas field development effect.
During exploitation of oil-gas field, than wide, effect can not look down upon for the application of fracturing technique, and it is that oil field realizes steady
Production, the target of high yield serve good support.The raising of fracturing technique effectively acted as linking up be connected the oily space of storage and
The effect of seepage channel.
Oil gas field uses composite bridge plug or big orifice bridging plug more both at home and abroad now, and such technique later stage needs to be ground
Milling operation, more liquid can be used during milling, secondary pollution can be produced to stratum, and the process of milling can cause
Time and the consumption of expense, it can be very good to avoid these problems using the anchoring system on solvable bridging plug.
The content of the invention
The utility model provides a kind of certain after pressure break terminates for technical problem present in solution known technology
Can be decomposed in time, eliminate milling operation, save the activity duration, protect oil-gas Layer, fixed, cost is cheap,
Anchoring system easy to assembly on solvable bridging plug.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：
A kind of anchoring system on solvable bridging plug, it is characterised in that：It is made including the material by can dissolve or degrade
Structure is identical and is mirrored into being symmetrically mounted on the upper slipses assembly and lower slipses assembly of upper cone and lower cone male cone (strobilus masculinus)；It is described
Upper and lower slips assembly includes slips monomer, the slips garter spring being installed on slips monomer；The outer wall of the slips monomer is up to
A ceramic particle is embedded with less, and the outer surface of the ceramic particle is higher by the outer wall of slips monomer, and ceramic particle is higher by portion
Into ramp structure, the minimum point on inclined-plane is concordant with the outer wall of slips monomer or outer wall less than slips monomer.
The utility model can also use following technical measures：
The outer wall of the slips monomer is radially provided with ceramic particle inlaid hole, and the ceramic particle inlaid hole embeds
Ceramic particle is filled, the upper surface of the ceramic particle is ramp structure.
The outer wall of the slips monomer is provided with the ceramic particle inlaid hole with slips monomer radial direction into 8~25 ° of angles,
Setting-in ceramic particle in the ceramic particle inlaid hole, the upper surface of the ceramic particle is planar structure.
The utility model has the advantages and positive effects of：Because the utility model uses above-mentioned technical proposal, save
The expense of liquid, tool expense, saves the activity duration, preferably protects stratum, prevent that stratum is secondary in later stage operation
Pollution, can reach the effect that existing composite bridge plug or big orifice bridging plug plays separate stratum fracfturing, while one after pressure break terminates
Fix time it is interior can decompose, eliminate milling operation, not only save the activity duration, also preferably protect oil-gas Layer.In addition,
Realize to compare have that fixed, cost is cheap, fills with the fixed and traditional bridging plug of overcoat occlusion using ceramic embedded particle
The advantages that with facilitating.

Embodiment
For invention, features and effects of the present utility model can be further appreciated that, following examples are hereby enumerated, and coordinate
Accompanying drawing describes in detail as follows：
Fig. 1 to Fig. 8, a kind of anchoring system being used on solvable bridging plug are referred to, including structure is identical and is mirrored into symmetrically
Installed in upper cone 2 and the upper slipses assembly 1-1 and lower slipses assembly 1-2 of the male cone (strobilus masculinus) of lower cone 3；Upper slipses assembly 1-1 is with
Slips assembly 1-2 material can be made up of soluble alloy material, for example, Al alloys andMg alloys, or degradable rigid
Macromolecule is made；The upper and lower slips assembly includes slips monomer 1-10, the slips garter spring 1- being installed on slips monomer
11；A ceramic particle 1-12, the high card release in outer surface of the ceramic particle are at least embedded with the outer wall of the slips monomer
The outer wall of watt monomer, ceramic particle are higher by portion into ramp structure, the minimum point on inclined-plane it is concordant with the outer wall of slips monomer or
Less than the outer wall of slips monomer.
When actually setting, the minimum point on inclined-plane is located at direction of exerting pressure；So pushing with throw-out collar, gradually realize and sit
Envelope, slips garter spring and guard circle garter spring are broken one by one during pushing, and glue bucket outwards deforms realization and sealed, on the slips inlayed
Ceramic particle be gradually engaged in the inwall of sleeve pipe, such bridging plug just forms about one in sleeve pipe and uniform irreversible set
Structure.
Refer to Fig. 3 to Fig. 6, in said structure, the outer wall of the slips monomer 1-10 is radially provided with ceramics
Grain inlaid hole 1-13, the interior setting-in ceramic particle of the ceramic particle inlaid hole, the upper surface of the ceramic particle is ramp structure.
Fig. 7 and Fig. 8 are referred to, slips monomer 1-10 can also use following structure, the slips monomer in said structure
1-10 outer wall is provided with the ceramic particle inlaid hole 1-13 with slips monomer radial direction into 8~25 ° of angles, the ceramic particle
Setting-in ceramic particle in inlaid hole, the upper surface of the ceramic particle is planar structure.
This anchoring system being used on solvable bridging plug is set using hydraulic pressure or igniter, and setting rear slips can be with
Prevent bridging plug from moving up or moving down, glue bucket 4 can shut annular space, block bridging plug lower channel after pitching, bridging plug can be held
By 70MPa pressure difference, after the completion of setting, pressure break, after waiting a period of time, the card on bridging plug can be carried out with overlying strata to bridging plug
Watt due to being dissolved, it is not enough to provide support force, bridging plug becomes to loosen, and bridging plug initially enters dissolving link, when waiting several days
Between after, the metal of whole bridging plug can all dissolve, and glue bucket is degraded into molecule, finally entirely be used for solvable bridging plug
On anchoring system be only left insoluble ceramic particle.
Upper slipses assembly and lower slipses assembly employ soluble material or degradable material, save liquid in later stage operation
The expense of body, tool expense, the activity duration is saved, preferably protects stratum, prevent stratum secondary pollution, can reach existing
There are composite bridge plug or big orifice bridging plug to play the effect of separate stratum fracfturing, while upper slipses assembly and lower slipses assembly terminate in pressure break
It can be decomposed in certain time afterwards, eliminate milling operation, not only saved the activity duration, also preferably protect oil gas
Layer.In addition, using ceramic embedded particle come realize be engaged fixed and traditional bridging plug with overcoat compared with there is fixed, cost
The advantages that cheap, easy to assembly.
Described above is only to preferred embodiment of the present utility model, not the utility model is made any formal
