Description
Technical field
The present invention relates to oilfield, specifically a kind of bored auto-excitation type guider for casing job, clean-out service.
Background technology
At present in casing job process, part well is unclean due to well, easily causes sand bridge or shaft bottom sand setting, and part well, due to cave-in or undergauge, causes that sleeve pipe cannot descend estimating position, wastes a large amount of man power and material, and cause tremendous economic to lose.
Summary of the invention
In order to overcome shaft bottom sand setting or cave-in in existing casing job to cause, sleeve pipe cannot descend the deficiency of estimating position, the present invention provides one can bore auto-excitation type guider, this can bore auto-excitation type guider and landwaste can be rinsed, carry, prevent landwaste from piling up and compacting in shaft bottom, and big particle diameter landwaste is played grinding, fragmentation, it is to avoid cause sand bridge or shaft bottom sand setting.
The technical scheme is that one can bore auto-excitation type guider, including urceolus, the upper end of urceolus is connected to box cupling, urceolus lower end is connected to guide seat, outer barrel is equipped with power assembly, described power assembly is provided externally with helical blade, and power assembly bottom is connected to servo-actuated impeller by couple axle, and servo-actuated impeller bottom is fixed with alloy tool steel bit.
The outer barrel on described power assembly top is fixed with air deflector by stablizing pin.
Described couple axle is externally connected to kuppe upper shell and kuppe lower house, it is connected by screw between kuppe upper shell and kuppe lower house, described kuppe lower house bottom is fixed on guide holder, and the upper surface of kuppe lower house is fixed with ratchet by pin, described couple axle is provided externally with ratchet, and described ratchet matches with the ratchet outside couple axle.
There is advantages that outer barrel is equipped with power assembly owing to taking such scheme, when operation, drilling fluid is with certain kinetic energy impact power assembly, being mechanical energy by kinetic energy and potential energy, impeller rotates, and the alloy tool steel bit for couple axle bottom provides power.Meanwhile, when alloy tool steel bit rotates, landwaste is produced shear action by drill bit, makes debris breaker, thus after being gone out shaft bottom by water jet, passing through annular space, returns to ground.Thus avoiding because bulky grain carries the danger of difficulty bit freezing, improving sand washing efficiency, solids-carrying capacity is higher, and range of application is wider.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described:
Shown in Fig. 1, Fig. 2, one can bore auto-excitation type guider, and including urceolus 2, the upper end of urceolus 2 is connected to box cupling 1, and box cupling 1 top is provided with casing threads, is connected with sleeve pipe.Urceolus 2 lower end is connected to guide seat 10, and urceolus 2 can undertake circumferential pressure, and the end of guide seat 10 is hemispherical, makes upper diameter more than lower diameter, it is possible to enters under guiding sleeve, and guide seat 10 inside is hollow.Urceolus 2 inside is fixed with air deflector 3 by stablizing pin 17, is connected to power assembly 4 by retainer needle bearing 16 in air deflector 3, and described power assembly 4 is provided externally with helical blade.Having several axial through holes on described air deflector 3, it is possible to play guide functions, fluid changes flow direction by air deflector 3, makes fluid impact at a certain angle on power assembly 4.Power assembly 4 bottom is connected to couple axle 6.Urceolus 2 lower end is internal by pin fixed guide seat 7, is rolled by punching press needle bearing 12 and be connected between described guide holder 7 and couple axle 6, and guide holder 7 plays guide functions, and fluid changes flow direction by guide holder.Described couple axle 6 bottom is connected to servo-actuated impeller 8, and servo-actuated impeller 8 bottom is fixed with alloy tool steel bit 9.Being connected to anti-decylization 11 on urceolus 2 inwall between described guide holder 7 and guide seat 10, anti-decylization 11 is possible to prevent the interior arrangement such as air deflector and power assembly to come off.Described couple axle 6 is externally connected to kuppe upper shell 5 and kuppe lower house 13, is connected by screw between kuppe upper shell 5 and kuppe lower house 13, and its outer surface is integrally formed arc-shaped, it is possible to play the effect changing flow direction.Described kuppe lower house 13 bottom is fixed on guide holder 7, and the upper surface of kuppe lower house 13 is fixed with ratchet 14 by pin 15, and described couple axle 6 is provided externally with ratchet, and described ratchet 14 matches with the ratchet outside couple axle 6.So, when the alloy tool steel bit 9 in bottom is had the trend of reversion by the effect of bottom external force, ratchet 14 coordinates jointly with the ratchet outside couple axle 6, it is possible to prevent couple axle 6 from reversing.
When operation, kinetic energy and potential energy, with certain kinetic energy impact power assembly 4, are mechanical energy by drilling fluid, and impeller rotates, and the special substance alloy tool steel bit 9 for couple axle 6 bottom provides power.Alloy tool steel bit 9 rotates, and when touching the bigger landwaste of particle diameter, landwaste is produced shear action by drill bit under rotation torque effect.Under twisting force, landwaste produces crack along shear surface, crushes gradually, disintegrates.Landwaste particle diameter diminishes, after being gone out shaft bottom by water jet, it is possible to pass through annular space, returns to ground.Simultaneously, the rotation of the impeller on alloy tool steel bit 9 forms eddy flow field, lateral shear, traction is produced in shaft bottom, make a concerted effort no longer straight down with what drilling well liquid columnpressure was formed, the landwaste promoting deposition produces, upset, and water jet impacts landwaste at a certain angle, and landwaste floats, leave shaft bottom, carried out well by drilling fluid.
