Abstract
The invention belongs to heating agent used in the liquid carbon dioxide fracturing device of the field such as coal mine construction, non-coal mine engineering, hydraulic engineering, Tunnel Engineering, it is mainly used in providing energy for liquid carbon dioxide fracturing device, liquid carbon dioxide transient evaporation in fracturing device is set to expand so as to reach the effect of fracturing exploitation oxidant, which is mainly characterized in that the mass percent of raw material and its each component is：Potassium nitrate：83.38%~87.80%, citric acid：4.88%~12.09%, stearic acid：3.63%~5.85%, manganese dioxide：0.60%~0.98%, carbon black：0.30%~0.49%.
Description
Technical field
The invention belongs to fields such as coal mine construction, non-coal mine engineering, hydraulic engineering, Tunnel Engineering, more particularly to
The heating agent that a kind of liquid carbon dioxide fracturing device uses.
Background technology
Current domestic liquid carbon dioxide split blasting gradually substitutes dangerous higher explosive in many fields, especially
It is in many high methane collieries or high methane engineer applied field, due to not having naked light or Mars to produce in blasting process, no
Job site gas can be discharged and produce dangerous matter sources, therefore, liquid carbon dioxide explosion is increasingly by the accreditation of people and joyous
Meet.
In addition, in many construction sites that can not use explosive, it is even more to show that its is superior that liquid carbon dioxide, which causes explosion,
Property, for example when needing blast cracking on peripheries such as residential building, heavy constructions, because explosive strength is huge, periphery can be produced huge
Big destruction and used by limitation；Liquid carbon dioxide split blasting is due to belonging to directional blasting and will not produce huge explosion
Thing splashes, and therefore, is widely used.
In liquid carbon dioxide fracturing device blasting system, heating agent is the key component of whole system in heating tube, is added
The effect of thermit powder is that moment, which occurs, to chemically react, and discharges chemical reaction heat, liquid carbon dioxide moment is turned from liquid phase
It is changed into gas phase, so as to provide energy for liquid carbon dioxide fracturing device explosion；The quality of heating agent directly influences fracturing device
Fracturing effect.
The content of the invention：
It is an object of the invention to provide a kind of heating agent for liquid carbon dioxide fracturing device, this liquid carbon dioxide causes
The mass percent of the heating agent raw material and its each component that split device is：Potassium nitrate：83.38%~87.80%, citric acid：
1.88%~12.09%, stearic acid：3.63%~5.85%, manganese dioxide：0.60%~0.98%, carbon black：0.30%~
0.49%.
Above-mentioned all raw material is technical grade, and wherein potassium nitrate is oxidant, and oxygen is provided for heating agent burning；Lemon
Acid and stearic acid are incendiary agent, are burnt with oxidant and chemical reaction generation heat occurs；Manganese dioxide is catalyst, promotes oxidation
The decomposition reaction of agent；Carbon black is colouring agent, and main function is uniformity coefficient during display heating agent physical mixed.
This heating agent has that units of heat caused by chemical reaction is high, chemical combustion is powered when opening quick-fried during fracturing not
Delay, under normal temperature and pressure open firing point do not catch fire, under normal temperature and pressure electronic ignition head point not, 1200 degree thermal-flames when roasting from
The features such as self-extinguishment.
Embodiment：
Technical scheme is further described with reference to embodiments, but is not the limitation to invention.
Embodiment 1
In proportioning described in embodiment 1, citric acid ratio is higher than stearic acid, and its object is to improve the burning speed of heating agent
Rate, on the premise of security performance is protected, the burn rate of agent is faster, reaction heat is higher, liquid carbon dioxide fracturing
Heating agent dosage of the device during fracturing is smaller, and its financial cost is lower.
Embodiment 2
In proportioning described in embodiment 2, stearic ratio is improved, its object is to larger improve the peace of heating agent
Full performance, under conditions of equal heating agent dosage, the security performance of heating agent is higher, production and the security incident using process
Probability is lower.
By taking the fracturing device of predominant tube diameter 51 in the market as an example, liquid carbon dioxide filling weight is at 0.85~1 kilogram, greatly
The heating agent dosage of most producers is all 90g, when filling 0.85~1 kilogram of carbon dioxide of liquid carbon dioxide in the present invention,
The minimum amount of heating agent can arrive 65g, and its financial cost will be less than like product, and security performance is higher than like product.
Table 1 show different embodiment test effect contrasts
