In order to carry out effectively crushing to the high rock of hardness in deep formation, propose in this application a kind of
Well system, Fig. 1 is the structural system schematic diagram of well system in the embodiment of the present invention, as shown in figure 1, well system includes：
Heating power flow jet flow drill 1, heating power flow jet flow drill 1 includes：Being provided with drill bit fixed disk 11, drill bit fixed disk 11 to be stretched
Heating power jet units 12 and water cooling runner 13 for conveying cooling water；It is arranged on the drill bit driving on drill bit fixed disk 11
Motor 14；The drill bit 15 being mutually connected with drill bit motor 14；It is arranged on the heating power jet reaction on drill bit fixed disk 11
Chamber unit 16, it is connected with heating power jet units 12 and for generating heating power Jetstream fluid, and heating power Jetstream fluid is conveyed
To heating power jet units 12；Heating power jet initiation unit 17, heating power jet initiation unit 17 is used for heating power jet reaction chamber list
Member 16 is lighted a fire；Feed-line unit 2, heating power jet reaction chamber unit of the feed-line unit 2 into heating power flow jet flow drill 1
16th, water cooling runner 13, heating power jet initiation unit 17 convey corresponding fluid and electric power；It is connected with feed-line unit 2
Fuel delivery unit 3, it is used to after fuel gas is pressurizeed be delivered to feed-line unit 2；It is connected with feed-line unit 2
Oxygen supply unit 5, it is used to that feed-line unit 2 will to be delivered to after oxygen pressing；It is connected with feed-line unit 2
Drilling fluid supply unit 4, it is used to after drilling fluid is pressurizeed deliver to feed-line unit 2；Drilling fluid reclamation unit 6, it can be with
Well mouth of oil well is connected drains into the drilling fluid on ground to be returned under recovery well.
By the application it was discovered by researchers that for deep layer hard formation, rock thermal cracking rock breaking method can be a kind of row
Effective manner, the fragment that can cause rock surface by rock thermal cracking broken rock peels off, and accelerates new in deep layer hard formation
Scar appear, and then the stress of drill bit 15 is released, drilling is lasting to be carried out, and may finally effectively raise drilling well
Speed.In order to cause rock thermal cracking and then reach the purpose of broken rock, heating power jet is have developed in this application and is broken
Rock drilling technology.The technology produces the high temperature heating power jet with certain temperature and pressure using the chemical energy of fuel combustion, enters
Conducted heat rapidly after row impact rock, cause rock surface to produce crack until cracking, further after new landwaste peels off surface
Drilling, reaches the purpose of quick rock-breaking and well-drilling.Above-mentioned well system be heating power jet rock-breaking and well-drilling technology in key device it
One.
Heating power flow jet flow drill 1 in well system is by the tripping in of feed-line unit 2 to deep layer hard formation, in order to have
What is imitated creeps into deep layer hard formation, by the drill bit motor 14 being arranged on drill bit fixed disk 11, what motor was produced
Driving force directly drives drill bit 15 to rotate by being connected, so that drill bit 15 slowly enters in deep layer hard formation to rock
Row drilling.Now, in order to effective fractured rock, fuel delivery unit 3 is anti-to heating power jet by feed-line unit 2
The fuel gas after the conveying pressurization of chamber unit 16 is answered, oxygen supply unit 5 is by feed-line unit 2 to heating power jet reaction chamber
Oxygen after the conveying pressurization of unit 16.
Then heating power jet reaction chamber unit 16 is lighted a fire by heating power jet initiation unit 17, at this point it is possible to control
Temperature in reaction chamber unit processed reaches 400-500 DEG C, and pressure reaches 30MPa, at this temperature and pressure, in injection reaction chamber
The water of generation is in a supercritical state.When temperature reaches 374.1 DEG C, when pressure reaches 21.83MPa, the water expanded by high temperature
Density and the vapor compressed by high pressure density it is just equal, water reaches supercriticality, shows HTHP
Monophasic fluid state.Now, drilling fluid supply unit 4 is defeated to heating power jet reaction chamber unit 16 by feed-line unit 2
Drilling fluid is sent, drilling fluid is coupled with the fluid of above-mentioned HTHP, be modulated into stable supercritical water and carbon dioxide
Heating power Jetstream fluid, heating power Jetstream fluid is projected from heating power jet units 12, and then directive rock, heating power Jetstream fluid impactite
Conducted heat rapidly after stone, cause rock surface to produce crack until cracking, at the same time, is issued to fast in the continuous rotation of drill bit 15
The purpose of fast broken rock.In above-mentioned whole process, pass through water cooling runner of the feed-line unit 2 constantly into drill bit fixed disk 11
13 conveying cooling waters, cooling water is used to cool down the mechanical structure around drill bit 15.Cooling water simultaneously will be broken with drilling fluid
Landwaste after broken carries out pit shaft, reaches the purpose of bottom-hole cleaning.Drilling fluid by being connected with well mouth of oil well on the ground
The drilling fluid and/or cooling water for draining into ground are returned under the recovery well of recovery unit 6.
Well system in the application is due to the motor of drill bit 15 is arranged on drill bit fixed disk 11, when drill bit is solid
When price fixing 11 is goed deep into deep well hard formation, motor can directly drive drill bit 15 to be rotated, in this way, can greatly improve
The efficiency of transmission of rotating speed and energy, it is to avoid set motor on the ground, by complicated drive connection by moment of torsion
It is transferred to the problem of energy transmission caused on the drill bit 15 of underground is low.Secondly, the heat having on drill bit fixed disk 11
Power jet reaction chamber unit 16, is conveyed single by feed-line unit 2, fuel delivery unit 3, oxygen supply unit 5, drilling fluid
First 4 grades convey corresponding reactive material to heating power jet reaction chamber unit 16, raw in the presence of heating power jet initiation unit 17
Into supercritical water and the heating power Jetstream fluid of carbon dioxide mix, the heating power Jetstream fluid simultaneously passes through the directive of heating power jet units 12
The rock that drill bit 15 is bored, heating power Jetstream fluid impact rock causes rock surface to produce crack until cracking, in drill bit 15 not
Disconnected rotation is issued to the purpose of quick broken rock, and by said process, this well system can be efficiently to hardness in portion stratum
High rock effectively crush, so as to improve drilling speed and drilling efficiency.
In above process, it is continuous to conveying around drill bit 15 by the water cooling runner 13 set on drill bit fixed disk 11
On the one hand cooling water, the cooling water plays the purpose of protection drill bit 15, prevents that the temperature of drill bit 15 is too high, so as to reach increase drill bit
Purpose during 15 brill；The landwaste produced in the drilling process of drill bit 15 is rinsed and taken away by still further aspect cooling water, by oil pipe and
Returned between the borehole wall and drain into ground, so can effectively prevent shaft bottom landwaste bit freezing so that drilling speed increases, improve drilling efficiency.
In order to be better understood from the well system in the application, it will be further explained and illustrated below.Fig. 3
For the profile of heating power flow jet flow drill 1 in well system in the embodiment of the present invention, as shown in figure 3, heating power flow jet flow drill 1 includes：
