Description
Technical field
The present invention relates to carbon dioxide fracturing device activator technical fields, living more particularly, to a kind of carbon dioxide fracturing device
Agent composite oxidant and preparation method thereof.
Background technique
Carbon dioxide fracturing device be the liquid carbon dioxide of certain mass is filling to fracturing pipe, quickly swashed using exploder
Activator, the expansion of liquid carbon dioxide transient evaporation are sent out, and generates high pressure.High pressure gas is discharged from bleeder, acts on coal
On (rock) body, to achieve the purpose that expand fracturing rock and coal seam.
Activator is installed in fracturing pipe main body tube, provides thermal energy, constitutive material for liquid carbon dioxide phase transformation gasification
The industrial chemicals mixture of mostly Oxidizing and Reducing Agents forms, therefore it provides the process of thermal energy is actually a redox
Process.Oxidant provides required oxygen for burning in the environment of fracturing closed frame tube anaerobic, and reducing agent, which then provides, makes liquid
Thermal energy required for carbon dioxide phase transformation is gasified.
Currently, oxidant used in carbon dioxide fracturing device activator mostly uses greatly strong oxidizer potassium hyperchlorate.Use height
Potassium chlorate at least has two large problems: first is that there is larger security risk, the friction sensitivity and impact sensitivity of potassium hyperchlorate are all larger than
National standard has certain risk；Simultaneously there is very big toxicity security risk in potassium hyperchlorate, have strong thorn to skin, mucous membrane
Swash property, and to environment nocuousness；Second is that potassium hyperchlorate production cost and use cost are high, produce one ton of potassium hyperchlorate power consumption and exist
9000 degree or more, expensive, when the river rises the boat goes up for corresponding use cost.
Therefore, it is really necessary to design a kind of carbon dioxide fracturing device activator composite oxidant and preparation method thereof, with
It solves the above problems.
Summary of the invention
In order to avoid the above problem, a kind of carbon dioxide fracturing device activator composite oxidant and its preparation side are provided
Method, performance are stablized, and reduce security risk, reduce costs.
A kind of carbon dioxide fracturing device activator composite oxidant provided by the invention and preparation method thereof, including it is following
The component of parts by weight:
Calcium sulfate 10-60,
Iron oxide 12-40,
Potassium hyperchlorate or potassium permanganate 1-10；
Wherein, calcium sulfate dead plaster.
Preferably, the parts by weight of calcium sulfate are 40-60.
Preferably, the parts by weight of iron oxide are 25-30.
The preparation method of carbon dioxide fracturing device activator composite oxidant, includes the following steps:
A, calcium sulfate is crushed；
B, iron oxide is crushed；
C, the pulvis in A and B is uniformly mixed；
D, by the mixture of potassium hyperchlorate or potassium permanganate and step C mixture, stir 10-30 minutes, composite oxidant
Product.
Preferably, calcium sulfate is crushed to 800-1000 mesh in A.
Preferably, brown iron oxide is broken to 800-1000 mesh in B.
Calcium sulfate is hyperoxic oxidant under with the presence of strong reductant and hot conditions, and effective oxygen content is reachable
40% or more, decomposition temperature is 1450 DEG C, is to decompose very safe oxidant, needs high temperature heat source that could decompose.Three oxygen
Change the effective oxygen content 30% of two iron, 1565 DEG C of decomposition temperature, decomposes caloric receptivity and reaction activity amount is low, reduction potential is high, is
Very strong oxidant.It can produce very high reaction speed and releasing greatly using reacting the characteristics of iron oxide with aluminium powder or strong reductant
The heat of amount forms 2000 DEG C or more high temperature.It is just met for the needs of calcium sulfate high temperature heat source decomposition.Under this hot conditions, sulphur
Sour calcium can rapidly react with aluminium powder or strong reductant and discharge a large amount of oxygen, and oxygen is further reacted with aluminium powder or strong reductant,
To form a chain redox reaction.The formation of this chain reaction must be just able to achieve by a kind of initiator, high
Potassium chlorate or potassium permanganate then play igniting and initiator in composite oxidant.Since potassium hyperchlorate or potassium permanganate are multiple
It closes oxidant and only plays initiator, therefore its dosage is seldom.
Compared with prior art, the invention has the following advantages:
1, performance is stablized；It can not be lighted or be ignited with open fire in air.
2, safe and reliable；The friction sensitivity and impact sensitivity of medicament are zero, highly-safe.
3, not moisture-sensitive；Due to having used calcium sulfate, it is both oxidant and anti-blushing agent, when storing composite oxidant
Between extend.
4, cost is reduced；Raw material sources are wide, easily purchase, cheap, saved production cost.
