Description
Technical field
Carbon dioxide fracturing device technical field is the utility model is related to, refers in particular to a kind of disposable carbon dioxide fracturing
Device.
Background technology
Carbon dioxide blasting technique was taken seriously and developed in the world since the nineteen fifties, was originally derived from
Being thought of as the coal-face of highly gassy mine and researching and developing for safety, has extended to the various fields for needing explosion at present.
Traditional explosive is blasting in once-through material, store it is dangerous high, during explosion it is destructive it is big, noise is big, dust is more, management and control is tight
Lattice, examination ＆ approval are cumbersome, are to tend to superseded blasting method.In today that high-tech is so flourishing, carbon dioxide gas blasting technique tool
The advantages that standby low noise, small dust, average price be cheap, easily operated use, there is obvious advantage compared with explosive, be by
Step substitutes the preferred blasting method of conventional explosives blasting method.
What is used at present is mostly the carbon dioxide fracturing device of recyclable reuse, and its design feature is：Closed by high intensity
Liquid storage pipe made of Jin Gang, equipped with filling valve, electro-heat equipment, lower end lets out energy device and lets out energy built with level pressure equipped with energy device is let out for upper end
Piece.Poured into from filling valve by liquid carbon dioxide in liquid storage pipe, acting on electric ignition hair by external power supply during explosion excites heating
Thermal response material in pipe makes its burning produce high temperature, and transient evaporation expands liquid carbon dioxide at high temperature, in liquid storage pipe
Extra-high is formed, energy piece is let out when carbon dioxide gas pressure exceedes the shear strength for letting out energy piece and is broken through, the two of super-pressure
Carbonoxide gas from let out can device let out can the very fast release in hole, producing strong impact to surrounding rock body makes its rupture.This structure

Expense makes the cost of this fracturing device seen and be reuse very high, is sealed further, since letting out energy piece and loading to exist when letting out energy device
Problem, fill it is bad will gas leakage, want during assembling great care to be just avoided that damage sealing, it is time-consuming, take a lot of work, furthermore, due to topping up
When liquid storage pipe be assembled into a closed cavity volume, the air pressure liter in pipe is made plus the pre- thermal evaporation characteristic of liquid carbon dioxide
Height heads on liquid and can not be filled with pipe, just must repeatedly be filled, put in order to fill the liquid carbon dioxide of enough constant weights, made
Liquid storage pipe cools down just can make liquid carbon dioxide fill enough amounts to certain low temperature, so generate a large amount of liquid two again
The waste of carbonoxide.
