With unfreezing function, drilling string stabilizer can be protruded when boring chance slim-hole and in wellbore in drill string tripping in bored borehole
Sillar when, the drilling string stabilizer that can be accessed in card column drill string, due to being to be swept away by force in the case where ground is not known into waiting ground
When instrument reaction and operator's discovery, drill string has been stuck, and cannot normally produce, especially the tripping in underground situation complexity
It is more easier the generation for above-mentioned accident occur, influences the normal production of safety, therefore, improvement and innovation gesture on stabilizer is must
Row.
Summary of the invention
For above situation, for the defect for solving the prior art, the purpose of the present invention is just to provide a kind of spherical spiral wing
Stabilizer can effectively solve drill string during preventing drilling string stabilizer in drilling process and make a trip and enter slim-hole and well
The generation of wall projection accident guarantees safety normal the problem of producing.
The technical solution that the present invention solves is a kind of spherical spiral wing stabilizer, including main body, and main body is inner via hole cylinder
Body, top are internal screw thread button, and lower part is external screw thread screw thread connector, are opened through isolation ring (neck) is fixed equipped with alternate in the middle part of main body
Upper sphere and lower sphere, be provided with helicla flute on the periphery of upper sphere, lower helicla flute, upper spiral shell be provided on the periphery of lower sphere
Spin slot is provided with ball screw wing, and lower helicla flute is provided with lower ball screw wing, inlays on upper ball screw wing and lower ball screw wing
There is hard-metal insert, the screw wing on each sphere is different.
The configuration of the present invention is simple, novel and unique is easy to install and use, and effect is good, can effectively prevent drill string in underground by card
Extremely, production efficiency is improved, is the innovation on oil-well drilling equipment stabilizer, there is good economic and social benefit.
Detailed description of the invention
Fig. 1 is structural front view of the invention.
Specific embodiment
It elaborates below in conjunction with attached drawing to a specific embodiment of the invention.
As shown in Figure 1, a kind of spherical spiral wing stabilizer of the present invention, including main body, main body 1 are inner via hole cylindrical body, on
Portion is internal screw thread button, lower part is external screw thread screw thread connector 7, is opened through isolation ring (neck) 4 is fixed equipped with alternate in the middle part of main body
Upper sphere A and lower sphere B, be provided on the periphery of upper sphere A above and below to upper helicla flute 3-1, be provided on the periphery of lower sphere B
Above and below to lower helicla flute 3-2, upper helicla flute 3-1 and lower helicla flute 3-2 it is upper and lower it is alternate be staggered, upper helicla flute 3-1 is provided with
Upper ball screw wing 2, lower helicla flute 3-2 are provided with lower ball screw wing 5, are inlaid on upper ball screw wing 2 and lower ball screw wing 5 hard
Matter carbide button 6, the screw wing on each sphere are different.
In order to guarantee using effect and easy to use, the identical cylinder for having through-hole of diameter is made in 1 metal of main body；
The upper ball screw wing 2, lower ball screw wing 5 are fin bodies made of metal, are respectively welded at helicla flute 3-
1, in lower helicla flute 3-2；
When the upper ball screw wing 2, lower ball screw wing 5 are 1-3, upper ball screw wing 2, lower ball screw wing 5 is alternate is staggered；
The hard-metal insert 6 is circle of the outer end with cutting edge, and inner end is embedded in ball screw wing 2 and lower ball screw wing
On 5；
The main body 1, upper sphere A, isolation ring 4, lower sphere B, the center of external screw thread screw thread connector 7 are (straight in same axis
Line) on.
The present invention includes main body 1, upper ball screw wing 2, helicla flute, isolation ring 4, lower ball spiral shell it can be seen from above structure
Rotor 5, hard-metal insert 6, main body 1 be inner via hole cylindrical body, top be internal screw thread button, lower part is external thread buckle, convenient for enter
Well downhole tool is connected up and down, one to three ball screw wing is presented in the middle part of main body 1, and orbicule is cut into helical form, is in 1-4
Screw wing and wing slot have isolation ring 4 to separate between upper ball screw wing 2 and lower ball screw wing 5, reduce well drilling detritus to upper ball spiral shell
The adhesion of rotor 2 and lower ball screw wing 5 is inlaid with hard-metal insert on spherical upper ball screw wing 2 and lower ball screw wing 5
6, enhance the wear-resisting property of stabilizer, and the screw wing on each sphere is different, can encounter hole diameter diminution well section when,
The processing appropriate that swells can be carried out to wellbore to lifting from the top and puting down for tool by drill string, guarantee that underground drill stem palpus benefit passes through, keep away
Exempt from drill string to wait indefinitely the generation of complex situations and accident in downhole card.
The main body, upper ball screw wing, helicla flute, isolation ring, lower ball screw wing, hard-metal insert, main body are interior logical
Hole cylindrical body, top be internal screw thread button, lower part is external thread buckle, convenient for enter well downhole tool up and down be connected, be in the middle part of main body 1
Existing one to three ball screw wing, and orbicule is cut into helical form, have between upper ball screw wing 2 and lower ball screw wing 5 every
It is separated from ring 4, adhesion of the well drilling detritus to upper ball screw wing 2 and lower ball screw wing 5 is reduced, in spherical upper ball screw wing 2
It is inlaid with hard-metal insert 6 on lower ball screw wing 5, enhances the wear-resisting property of stabilizer, and the screw wing on each sphere is each
It is not identical, it can be when encountering the well section of hole diameter diminution, it can be appropriate to wellbore progress to lifting from the top and puting down for tool by drill string
Swell processing, guarantee underground drill stem must benefit pass through, avoid drill string from waiting indefinitely the generation of complex situations and accident in downhole card.
Service condition of the invention is that the 2+3 spherical spiral wing stabilizer processed is even linked into brill by design requirement
On column, when boring instantly, with drill string downlink, when meeting slim-hole, lower ball screw wing 5 is hampered first, can under pressure, under
Ball screw wing 5 swells by force to wellbore, and be it is spherical, can be simply by, can be right when upper ball screw wing 2 encounters again
Wellbore carry out again outward it is swollen, play the purpose for the wellbore that swells, while scraping can be carried out to the landwaste on bore hole inside wall, and not
Easily cause stuck complex situations, when drill bit reach shaft bottom after, normal drillng operation can be carried out, meanwhile, when has needed out brill
When column, upper ball screw wing 2 can initially encounter slim-hole and phenomena such as be hampered, at this moment can be by lifting from the top and puting down, and swell former wellbore,
It completes to lift process out in drilling tool safety.Pass through spherical upper ball screw wing 2 and lower ball screw wing 5 answering in drilling
With, preferably resolve stabilization in drill string and make a trip in be effectively reduced to make a trip and meet the generation problem of card phenomenon,
The safety for improving tool, extends service life.
Structure of the invention novel and unique, advantages of simple enhance the ability to work of drilling string stabilizer in drilling process, enhance
Safety, and bit freezing probability can be timely and effectively reduced, the problem of live operability is improved, drilling well underground engineering is reduced
The generation of accident, easy to use, effect is good, is the innovation on drilling well stabilizer, has good economic and social benefit.
