Description
Technical field
The present invention relates to oil-well drilling equipment, especially a kind of interchangeable straight wing stabilizer.
Background technique
It, can be by setting in drill string to guarantee that institute's bored borehole forms wellbore according to engineering design requirements during wellbore construction
Meter requires to access drilling string stabilizer appropriate, existing drilling string stabilizer be broadly divided into fixed spiral stabilizer, straight wing stabilizer,
Idler wheel stabilizer, replaceable sleeve stabilizer, they are fixed-wing, non-exchange, due to non-exchange, as long as so outer diameter slightly
What reduction must more renew, due to studding with corresponding hard alloy outside product, reparation maintenance is relatively difficult, will not at present
Maintenance and repair are carried out, therefore, tool waste is larger, needs a kind of product that can replace the wing, accomplishes and can play stabilizer
Effect, and the product that can be replaced convenient for scene, for this purpose, it is imperative to design completely new interchangeable straight wing stabilizer.
Summary of the invention
For above situation, for the defect for solving the prior art, it is steady that the purpose of the present invention is just to provide a kind of interchangeable straight wing
Determine device, can effectively solve drilling string stabilizer centralizer wing can only use cannot scene carry out maintenance replacement the case where, drilling well use
Later, tool inspection out is played, as long as it is not up to standard to find that product may wear to, so that it may perform on-site replacement, reduce because of tool cost
It is high and used reluctantly, cause drilling quality not up to standard or drilling parameter cannot optimize implementation, and increase drilling period
The problem of.
The technical solution that the present invention solves is a kind of interchangeable straight wing stabilizer, including body, steady pin shaft and the straight dovetail wing,
Body is inner via hole cylindrical body, and top is that internal screw thread button and drill string top split-phase connect, and lower part is external thread buckle and lower drill string part point
It is connected, middle part outer circle is greater than the cylinder convex body of both ends cylinder in outside swell diameter, is provided on the peripheral wall of cylinder convex body alternate
The uniformly distributed straight dovetail groove in three to four roads is opened, length and the corresponding straight dovetail wing are corresponding, in straight dovetail wing insertion groove, with body
Be tightly secured together, under dovetail-shape formula and dovetail groove match, be thereon that trapezoidal shape is presented in both sides chamfering, when the straight dovetail wing
Dovetail insertion on body, there is the horizontal perforation for being inserted into steady pin shaft in the open end of the straight dovetail groove of body, is inserted in horizontal perforation
Steady pin shaft blocks the channel of exiting of the straight dovetail wing, and straight dovetail trench bottom is useful in fixed screw hole, and spiral shell is provided with fixed spiral shell
Bolt, limits exiting for steady pin shaft, further fixes the straight dovetail wing, steady pin shaft be it is cylindric, there are a thin neck, fixing bolt in centre
It is passed through against thin neck, limits steady pin shaft and moved left and right along axis, when needing replacing the straight dovetail wing, only need to laid down bolt, extract out
Steady pin shaft takes out the straight dovetail wing out of straight dovetail groove on body, and the new straight dovetail wing, guarantees the normal of stabilizer needed for changing
It uses.
Structure of the invention novel and unique, advantages of simple, using effect is good, improves the safety of tool, extends use
Service life, can scene carry out replacing the straight dovetail wing, make bored borehole keep borehole diameter constant, meet live actual demand, effectively
Drilling safety environment and production work efficiency are improved, is the innovation on drilling string stabilizer.

Bolt 2, limits exiting for steady pin shaft 3, further fixes the straight dovetail wing 4, steady pin shaft 3 be it is cylindric, there is a thin neck in centre, fixed
Bolt 2 is passed through against thin neck, is limited steady pin shaft and is moved left and right along axis, when needing replacing the straight dovetail wing, only need to lay down bolt,
It extracts steady pin shaft out, the straight dovetail wing is taken out out of straight dovetail groove on body, the new straight dovetail wing, guarantees stabilizer needed for changing
Normal use.
In order to guarantee using effect, the internal screw thread button 5 is small in the big inner end of oral area, and internal thread circular hole on hole wall
Channel-shaped；
The external thread buckle 6 is in the conical hollow that point diameter is small, rear end diameter is big；
There is the through-hole 8 penetrated through above and below at the center of the body 1；
The straight dovetail wing 4 is tabular, and outer end face two sides take the form of inclined plane 4-1；
7 both ends of cylinder convex body are in inclined-plane 1-1.
A kind of interchangeable straight wing stabilizer of the present invention it can be seen from above structure, including body (main body), bolt, steady pin
Axis, the straight dovetail wing, body 1 are inner via hole cylindrical body, and top is that internal screw thread button and drill string top split-phase connect, and lower part is external thread buckle
Connect with lower drill string part split-phase, outer circle presentation in middle part is cylindric, at columned one, is provided with the straight dovetail groove in three to four roads, and not
Perforation, length and the corresponding straight dovetail wing 4 are corresponding, and just the straight dovetail wing 4 is inserted, and the straight dovetail wing 4 is plate, under
Dovetail-shape formula and dovetail groove match, and trapezoidal shape is presented for both sides chamfering thereon, when dovetail of the straight dovetail wing on body 1 is inserted
Entering, there is a horizontal perforation in the open end of the straight dovetail groove of body 1, for being inserted into steady pin shaft 3, the channel of exiting of the straight dovetail wing 4 is blocked, and
Straight dovetail trench bottom has a screw hole, for installing fixing bolt 2, limits exiting for steady pin shaft 3, further fixes the straight dovetail wing
4, steady pin shaft 3 be it is cylindric, as soon as there is thin neck in centre, bolt 2 passes through and is close to from there, limits steady pin shaft 3 along axis or so
It is mobile, after being installed, become a complete product, when requiring replacement, only need to lay down bolt 2, extract steady pin shaft 3 out, from
The straight dovetail wing 4 is taken out in straight dovetail groove on body, the new straight dovetail wing 4 needed for changing just, guarantees stabilizer just
It is often used.
