Description
Technical field
The present invention relates to a kind of gas producing medicinal, more particularly to a kind of essential safety, gas production are big, the warm low and combustion gas of combustion is clean
Gas producing medicinal.
Background technology
At present, China, which is used for the most widely used method of fractured rock, mainly blasting procedure and mechanical rock breaking method, and other are existing
For breaking technique for rock, such as water jet method, plasma method, laser method, supercritical ultrasonics technology, because of production efficiency, economy and regionality
Limitation, can only as broken rock a kind of supplementary means.
The blasting boreholes method broken rock mode being combined in machine drilling and explosive is set up with overall efficiency height in the longer term
Interior but blast broken rock powder burning speed is exceedingly fast in occupation of considerable status, and pressure rising time is Microsecond grade, surge pressure pole
Height, energy almost all is consumed in the comminuted destruction on rock of borehole surface, and fracturing process is difficult to control to, and formation fracture comes
Not as good as expansion and extension, make rock surface formation compacted lift and produced with 10 ~ 100 microscopic checks, the long 10 ~ 100mm of seam.And
It is big to the perturbation of protolith, the periphery rock failure mechanism of rock is easily caused, there is supporting difficulty, fractured rock lumpiness is uneven.
High enegry gas fracturing is the technology grown up 1980s, is widely used to opening for oil gas field
Adopt, the technical process is to produce high temperature, gases at high pressure with gunpowder or propellant combustion moment, and a kind of skill of pressure break is carried out to rock stratum
Art.High enegry gas fracturing powder burning speed, pressure rising time is Millisecond, and surge pressure is higher, and energy transmission is very fast,
Thus not by formation rock Stress Control, radially radial a plurality of long crack can be formed.
And seam, cutting field are made in rock media, in order to exploit stone material by design, High-Energy Gas Fracturing Technology is proposed
Some is required below：
（1）Effectively：Make seam controllable, can complete to cut by design size.
（2）It is cheap.
（3）Use safety.
（4）Environmental protection, pollution-free and nontoxicity.
（5）Fracturing technique is without geographical restrictions.
It there is no the gas producing medicinal product for meeting above-mentioned condition at present.
The content of the invention
In view of the shortcomings of the prior art, object of the present invention is to provide essential safety, gas production be big, combustion temperature is low and combustion
The clean gas producing medicinal of gas.
A kind of gas producing medicinal of the present invention, including ammonium oxalate and chlorate or perchlorate.
The present invention each component and its weight ratio be：Ammonium oxalate is 30 ~ 60wt%, chlorate or perchlorate be 40 ~
70wt%。
The present invention each component and its weight ratio be preferably：Ammonium oxalate is 50 ~ 55wt%, chlorate or perchlorate
For 45 ~ 50wt%.
Ammonium oxalate of the present invention is reducing agent, is Diammonium oxalate monohydrate or anhydrous oxalic acid ammonium.
The granularity of the ammonium oxalate is 5 μm ~ 50 μm.
Chlorate of the present invention is one kind or the combination of sodium chlorate or potassium chlorate.
Perchlorate of the present invention is one kind or combination of lithium perchlorate or sodium perchlorate or potassium hyperchlorate.
The granularity of chlorate or perchlorate of the present invention is 10 μm ~ 100 μm.
The present invention works under the environmental stress more than 5MPa, and the primary product of course of reaction is H2O、CO2、N2Deng hair
Tolerance is more than 600L/kg, and combustion temperature is low（Less than 1700K）, reaction initial pressure High Availabitity is in the formation of initial rock fracture, and gas
State water molar content is more than 50%, as crack is expanded, and pressure declines and temperature reduction, and vaporous water is gradated as aqueous water, pressure
Power drastically declines；Production process safety, can make seam field as power source, safe automobile air bag, floating air-bag, gas pressure break.
The beneficial effects of the invention are as follows：
（1）Pressure controllable：Pressure break cutting operation can be carried out by design production model.
（2）Essential safety：It is difficult to ignite under normal temperature and pressure, Flammability limits pressure reaches 5MPa, reaction can be stopped after pressure release.
（3）It is cheap：The conventional component that is easy to get is selected, raw material are easy to obtain.
（4）Environmental protection：Reaction product is clean, predominantly H2O、CO2、N2Deng.
