Specific embodiment：
The utility model is specifically described below in conjunction with the accompanying drawings：
A kind of mixed gas gas filling device of vehicular HTHP for petroleum thermal recovery of the utility model, it is by HTHP
Equipment is arranged on car body 1.Due to being distributed in different regions oil well more, using building steam injection station more than conventional steam injection equipment,
Then pipeline installation is so both occupied cultivated land to different oil wells, and construction costs is high etc., and drawback is all displayed；And this practicality
It is new without very high cost, without complicated construction work, it is necessary to arrive which oil well implements operation, just flexibly drive to arrive very much
There, next oil well is arrived after the completion of steam injection again and proceeds steam injection.The patented technology of Patent No. 200710023550.5 is just
Do not possess such technical conditions, its implementation is that crane reaches scene and installed, debugged, constructed, and increased answering for implementation
Miscellaneous degree.
The most important part of the utility model is generator 9, and generator 9 is made up of 3 parts, and front portion is cold without water circulation
But coiled hair 10, what is be connected with coiled hair 10 is combustion chamber 16, and what is be connected with combustion chamber 16 is mixing chamber 20.Conventional combustion chamber 16
Inwall is provided with collet, generally resistant to elevated temperatures ceramic material, but resistant to elevated temperatures ceramic material or often it is ablated fall, block up
Plug necking bushing；The utility model does not have collet, and inner bag is alloy material global formation, and the trade mark has higher for JIS G5151
Heat resistance, so, the conventional steam injection time is up to more than 5 hours, and using inner bag of the present utility model design can reach
48 hours.
Coiled hair 10 is provided with air inlet 11, oil inlet 12 and igniter 13；The tail end of combustion chamber 16 is provided with the He of thermosistor 17
Necking bushing 19.
The column of flame formed when lighting in combustion chamber 16 always back burns coiled hair, it is contemplated that to this be air blast pressure with
The matching problem of necking bushing 19, the also pressure including oil well；If the cylinder segment length of necking bushing 19 is 8 ~ 12mm, internal diameter
In the case of 6 ~ 14mm, the blast pressure of air compressor machine 5 should make flame toward fore blow in 23 ~ 25MPa, superpower pressure, while
Extension extension of the igniter 13 to inner bag 24, general igniter is deep into 15 ~ 20mm in combustion chamber and can reach requirement；So, originally
Utility model solves the problems, such as that conventional coiled hair also needs to cooling system cooling, reduces the complexity of processing, also drops simultaneously
Low maintenance cost.
Spiral channel 15 is provided between the housing 14 and inner bag 24 of combustion chamber 16；The entrance of spiral channel 15 is arranged on burning
The side of room 16, the other end is arranged in thermosistor 17；Conventional gas filling device is additionally provided with the spiral cooling water channel on coiled hair；This
A little cooling water channels are easy to fouling at high temperature, and shut-down phenomenon often occurs.The utility model uses softened water Cooling Design, very
Solve the problems, such as that fouling and clogging is stopped work well.
Silencer cover 21 is provided with mixing chamber 20, afterbody is provided with venthole 22.
Embodiment：
Control room 2 on car body 1, is the general control system of steam injection equipment, realize igniting, valve opening, steam injection, water filling, cooling,
The operation such as exhaust and valve closing.Nitrogen and carbon dioxide gas produce the pressure of 23 ~ 25MPa to enter into generator by air compressor machine.
The nitrogen that is passed through, carbon dioxide gas have the effect of mixed phase, viscosity reduction, can well improve the recovery ratio of crude oil.Igniter 13
The diesel oil that atomizer sprays is lighted, HTHP is formed in the combustion chamber 16 in generator 9；Softened water is along spiral channel 15
Combustion chamber 16 is lowered the temperature, is entered into finally by the entrance of thermosistor 17 and is vaporized in combustion chamber 16,23 ~ 25MPa of formation,
Temperature is that 350 DEG C of gaseous mixture enters into mixing chamber 20 and is sufficiently mixed, then is injected into underground by venthole 22, completes steam injection behaviour
Make.Typically, the nitrogen in mixed steam accounts for 40%, and carbon dioxide gas accounts for 10%, and remaining is vapor.
Due to the principle expanded with heat and contract with cold, the oil pipe of well head is above ground level sometimes more than one meter；But generator and oil pipe
Connection is all Hard link, so be provided with lifter 23 below car body 1, to adapt to steam injection the need for.
Because the mixed steam that generator 9 is produced is injected into underground, so equipment of the present utility model belongs to 0 discharge, it is
Environmental Protection Agency's freed-from-inspection product.
This equipment obtains good effect in Jilin Oil Field experiment.The oil well in Jilin Oil Field Songyuan City area is generally super-viscous oil oil
Well, conventional steam-assisted recovery moisture content is too high, and some are up to 80%, without extraction value.The utility model uses mixed gas steam injection simultaneously
The method of super-pressure, in well head is directly injected into oil reservoir, its bulk effect can promptly supplement and improve the pressure of oil reservoir
Power, its heat effect can will be greatly reduced the viscosity of crude oil, and nitrogen and carbon dioxide can promptly melt in crude oil reduction stream
Resistance, makes oil well liquid level significantly rise；Often this oil well stream-injection, can drive the pasta of several oil wells around to rise；With
3.8 tons are had a daily output of toward single port oil well, using the utility model after, can realize turning over 2 ~ 5 times of volume increase.
