Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings:
Embodiment 1:
As it is shown in figure 1, a kind of jet-propelled scraper, it is mainly used in the rig that can use anti-overflow pipe.Its bag
Including anti-overflow pipe 1, air nozzle 2, supply hard tube line bag 3, gas pipeline (is not drawn into this structure) in figure；Anti-overflow pipe
1 outer sheathed described supply hard tube line bag 3, the inwall of the outer wall of anti-overflow pipe 1 and described supply hard tube line bag 3 it
Between form air chamber 4, described supply hard tube line bag 3 connects gas pipeline, and gas pipeline connects source of the gas；Anti-overflow pipe 1
Tube wall on multiple air nozzle 2 is installed, the gas outlet 7 of air nozzle 2 is towards described anti-overflow pipe 1 tube chamber, jet
The air inlet 8 of mouth 2 is towards described air chamber 4.
Using method: the size of the anti-overflow pipe 1 that this scraper uses is equal to drilling crew and commonly uses anti-overflow pipe, can
It is directly welded at the upper end of drilling crew's anti-overflow pipe, it is simple to drilling team constructs.During air blowing, at anti-overflow pipe 1, spray is installed
Valve 2, connects gas pipeline by supply hard tube line bag 3, blows in anti-overflow pipe 1 from air nozzle 2 gas out
Drilling tool, blows clean surface of drill stem mud, and spudding up and down is to observe surface of drill stem drilling fluid or mud
Being insufflated the effect of cleaning, can pull out of hole time suitable, it is ensured that drilling tool rises when being raised to drilling floor surface, drilling floor surface cleans,
Personnel can be prevented to slide into, it is simple to operation.
During use, in order to prevent pouring in down a chimney and block, it is only necessary to open scraper in daily construction variable interval
?；Or guarantee when installing that nozzle is when drilling tool normally creeps on mud liquid level.
The advantage of scraper of the present invention:
1, scraping mud efficiency high, labor intensity is low, operates safe and simple.
2, operation principle is advanced simple, and reasonable in design is simple to operate, fully mechanized operation, saves
Manpower, highly effective and safe.
3, move and install the most convenient, occupied ground size and drilling team now with anti-overflow pipe essentially identical.
Embodiment 2:
On the basis of embodiment 1, referring to Fig. 2 and 3, described anti-overflow pipe 1 is uniformly opened on same circumference
If multiple installing holes (figure is not marked), in each installing hole, it is respectively mounted a described air nozzle 2.
Multiple installing holes on anti-overflow pipe 1 are uniformly distributed by the present invention, thus can make multiple air nozzle 2
The gas of ejection can be stablized, blow to surface of drill stem equably, and as shown in Figure 3, gas is the most permissible
Blow to anti-overflow pipe 1 major part cross section so that in surface of drill stem, the mud on regional can blow clean,
Avoid gas to concentrate and be only capable of blowing away problem generation as the slurry on respective regions in surface of drill stem.
Embodiment 3
Implementing on the basis of 2, described anti-overflow pipe 1 is connected to installing hole by the way of gluing or welding
In, make air nozzle 2 be securely attached on anti-overflow pipe 1, it is ensured that blow smooth and stable carrying out.
Embodiment 4
On the basis of embodiment 1, as in figure 2 it is shown, the gas outlet of air nozzle 2 is to anti-overflow pipe 1 central shaft
The distance of line to the distance of anti-overflow pipe 1 central axis, makes the peace of air nozzle 2 more than described anti-overflow pipe 1 inwall
Holding position is inwardly less than anti-overflow pipe 1 inwall, and when preventing from making a trip, drilling tool breaks air nozzle 2.
Embodiment 5
On the basis of embodiment 1, as shown in Figure 4 and Figure 5, described air nozzle 2 is in both ends open
Empty round table-like, it is provided with tapered injection pore 5 in air nozzle 2, the diameter of tapered injection pore 5 is towards gas outlet 7
Direction flaring, so can improve the emitted dose arriving drilling tool, it is easier to wash the mud on drilling tool.
The air nozzle 2 of the present invention can be decided according to the actual requirements system, it is also possible to by change nozzle form,
Size changes ejection gas direction and tolerance.The most as shown in Figure 4 and Figure 5, two in Fig. 4 and Fig. 5
Varying in size of air nozzle 2.In Fig. 4, the puff prot diameter of air nozzle 2 is more than the spray of air nozzle 2 in Fig. 5
The diameter of QI KOU, so the tolerance of air nozzle 2 is more than the tolerance of air nozzle 2 in Fig. 5 in Fig. 4.
Embodiment 6
On the basis of embodiment 1, gas pipeline (being not drawn into this structure in figure) sets source of the gas regulation switch (in figure
It is not drawn into this structure), can be opened at any time by source of the gas regulation switch (being not drawn into this structure in figure) and close down, it is achieved
Ventilate, die and the control of tolerance size.
Before trip-out, gas pipeline is connected with drilling crew source of the gas, opens source of the gas regulation switch and blow, up and down
Drilling tool is insufflated cleaning effect with observe the drilling fluid of surface of drill stem or mud, can pull out of hole time suitable,
Midway can be regulated on-off control tolerance size according to cleaning effect by source of the gas, above puts that to put drilling tool unaffected.
During using, in order to prevent pouring in down a chimney and block, it is only necessary to open in the regulation of daily construction variable interval source of the gas
Pass air-blowing.
Embodiment 7
On the basis of embodiment 1, described supply hard tube line bag 3 is provided with gas pipeline connecting tube 6, described gas
Pipeline connecting tube 6 connects gas pipeline.Gas pipeline is made to be firmly installed in for air hardening by gas pipeline connecting tube 6
Pipeline bag 3, it is ensured that gas pipeline stablizes lasting supply.
Embodiment 8
On the basis of embodiment 1, discharge opeing outlet is set below described supply hard tube line bag 3 and (figure is not drawn
Go out this structure), discharge opeing outlet seals when air nozzle is blown.When scraper is not turned on, once mud pours in down a chimney
To scraper, the mud poured in down a chimney can be discharged, be prevented scraper blocked by discharge opeing outlet.
Obviously, those skilled in the art can carry out various change and modification without deviating from this to the present invention
Bright spirit and scope.So, if the present invention these amendment and modification belong to the claims in the present invention and
