One end of ball is connect with the bottom of the lower semisphere, and the inside of the cylindrical body is equipped with cavity, the episphere, the lower semisphere
It is made with the cylindrical body of soluble material.
The beneficial effects of the utility model are: the cavity is provided with hydrotropy pulvis, which is vanillic aldehyde, described
The soluble material of episphere, the lower semisphere and the cylindrical body be made of magnesium alloy can solution, can 30 DEG C-
It is dissolved at a temperature of 320 DEG C.Dissolution time is adjusted according to the ratio of magnalium ingredient.Preferably, magnesium alloy is by following heavy
The group of amount percentage is grouped as: magnesium 25~80%, the impurity that surplus is aluminium and content≤1%.It is highly preferred that magnesium alloy is under
The group for stating weight percent is grouped as: magnesium 42~68%, the impurity that surplus is aluminium and content≤1%.This solvable fracturing device class
It is similar to capsule shape, which can satisfy the pressure-bearing demand of 70MPa pressure difference, will not be because of the presence of cavity
And it deforms or is crushed.Therefore can be in setting process, the episphere or lower semisphere of the solvable fracturing device of the utility model
Ball arc can cooperate with the ball seat of solvable bridge plug, formed sealing carry out pressure break.After the completion of setting, solvable fracturing device is molten
It solves, the hydrotropy pulvis in dissolved cavity is distributed in liquid, is helped the dissolution of bridge plug, is accelerated the dissolved efficiency of bridge plug.This
Utility model is also used as independent component and enters the position specified in pit shaft, then after high-temperature digestion, discharges in cavity
Hydrotropy pulvis.
Based on the above technical solution, the utility model can also do following improvement.
Further, the bottom of the episphere is equipped with concave station A, and the bottom of the lower semisphere is equipped with concave station B, the cylindrical body
Both ends be equipped with boss, the cylindrical body and the episphere pass through the boss of the cylindrical member at one end and the mistake of the concave station A
It is full of and cooperates together.The cylindrical body and the lower semisphere pass through the convex of the one end of the cylindrical body far from the episphere
The interference fit of platform and the concave station B links together.
Beneficial effect using above-mentioned further scheme is the connection enhanced convenience of episphere and lower semisphere and cylindrical body,
And think cylindrical body cavity injection hydrotropy pulvis be more easier, and be combined into it is even closer when sphere so that entirely may be used
The production efficiency of dissolving device is higher.
Further, one end of the episphere and the cylindrical body welds together, the lower semisphere and the cylindrical body
One end far from the episphere welds together.
Beneficial effect using above-mentioned further scheme is that the connection of episphere and lower semisphere and cylindrical body is more firm.
Further, one end of the cavity is connected to one end of the cylindrical body.
Beneficial effect using above-mentioned further scheme is only needed when other reagent reinforcing effects are added in cavity
Reagent can be added into cavity by opening episphere or lower semisphere.
Further, it is seemingly coating that the outer surface of the episphere, the lower semisphere and the cylindrical body, which has,.
Beneficial effect using above-mentioned further scheme is the solvable fracturing device before carrying out fracturing technology operation
Division will not be dissolved, after carrying out fracturing work, the turbid coating of anti-corrosion, which is destroyed, to be dissolved.
Further, there is frosted layer in the outer surface of the episphere, the lower semisphere and the cylindrical body.
Beneficial effect using above-mentioned further scheme is in setting process, the frictional force of solvable fracturing device and ball seat etc.
It is bigger, cooperate even closer.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
In attached drawing, parts list represented by the reference numerals are as follows:
1, episphere, 2, cylindrical body, 3, cavity, 4, lower semisphere, 5, boss, 6, concave station A, 7, concave station B
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figure 1, a kind of solvable fracturing device, including episphere 1, lower semisphere 4 and cylindrical body 2, the episphere 1
Bottom is set there are two opposite concave station A6, and the bottom of the lower semisphere 4 is set there are two opposite concave station B7, the cylindrical body 2
Both ends are respectively equipped with two opposite boss 5, and the cylindrical body 2 and the episphere 1 pass through the boss of described 2 one end of cylindrical body
5 link together with the interference fit of the concave station A6.The cylindrical body 2 and the lower semisphere 4 are separate by the cylindrical body 2
The boss 5 of one end of the episphere 1 and the interference fit of the concave station B7 link together.The inside of the cylindrical body 2 is set
There is cavity 3, the cavity 3 is provided with hydrotropy pulvis, and the episphere 1, the lower semisphere 4 and the cylindrical body 2 are by solvable
Material is made.One end of the cavity 3 is connected to one end of the cylindrical body 2, and the solvable fracturing device is similar to capsule shape.
The solvable fracturing device completion is set into closures, the ball seat cooperation of the ball arc and solvable bridge plug of lower semisphere 4 when
It waits, since there is frosted layer in the outer surface of the episphere 1, the lower semisphere 4 and the cylindrical body 2, so that cooperation is even closer,
It is more firm to block.Since there is erosion shield in the outer surface of the episphere 1, the lower semisphere 4 and the cylindrical body 2,
So solvable fracturing device will not dissolve when fracturing work, after carrying out fracturing work, erosion shield is destroyed, solvable pressure
