Description
Technical field
The utility model is related to a kind of milling shoe, more particularly to a kind of milling shoe for protecting fish injury-free.
Background technology
In Process of Oil Well Drilling, for various reasons, drill string lock of tool drilling happens occasionally.If accident treatment is too late
When, underground situation complication is easily caused, the completion efficiency of oil drilling is influenceed.Bit freezing be accomplished by by inject decoder, under
Bumper jar jarring, by covering milling drill string and carrying out the measures such as back-off operation salvage drill string.During set milling, milling shoe can be to falling
Fish produces destruction, and heavy losses can be produced if fish is expensive instrument.For such a situation, we should design a kind of well
Under dedicated for preventing guarantor's heart milling shoe that fish is worn and torn, integrality when fish goes out well has very big guarantee.
The content of the invention
The drawbacks described above that the purpose of this utility model is present aiming at prior art protects fish not to be damaged there is provided one kind
The milling shoe of wound, effectively carries out effective salvaging to underground fish, while easier solve the underground that viscous suction bit freezing is caused
Accident.
Its technical scheme is：Including body, milling cylinder, milling shoe, in the inside of body provided with milling cylinder, in the lower outside of body
Provided with milling shoe, the lower inside of the milling cylinder is smooth, on the top of body provided with milling cylinder screw thread, is provided with the outside of the milling shoe
Mill teeth, is provided with smooth on the inside of chamfering, the fillet surface of chamfering in the bottom of milling shoe, provided with three chip areas on the milling shoe.
Three chip area angles on above-mentioned milling shoe are 120 degree.
Chamfering on above-mentioned milling shoe forms the gradient with milling cylinder.
The beneficial effects of the utility model are：The utility model is effective to carry out effective salvaging to underground fish, simultaneously
It is easier solve it is viscous inhale the down-hole accident that bit freezing is caused, milling shoe bottom is provided with the chamfering that interior light-metering is slided, and is connected with body and is in
Certain gradient, is effectively protected underground fish not by broken landwaste and secondary abrasion of the mill teeth to fish head of dropping, milling shoe has
Three chip areas, angle is 120 degree, effectively solves the slower phenomenon of drilling depth caused by the earth cuttings accumulation that milling is fallen, from
And more efficiently set milling underground fish head is reached, while reducing broken landwaste and secondary abrasion of the mill teeth to fish head of dropping.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model；
In figure：Body 1, mill teeth 2, chamfering 3, chip area 4, milling cylinder screw thread 5, milling cylinder 6, milling shoe 7.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
The utility model includes body 1, milling cylinder 6, milling shoe 7, in the inside of body 1 provided with milling cylinder 6, in the bottom of body 1
Outside is provided with milling shoe 7, and the lower inside of the milling cylinder 6 is smooth, is conducive to milling cylinder to be easier to entangle shaft bottom fish head, right as far as possible
Shaft bottom fish head is protected, and on the top of body 1 provided with milling cylinder screw thread 5, mill teeth 2 is provided with the outside of the milling shoe 7, in milling shoe
7 bottom is provided with smooth on the inside of chamfering 3, the fillet surface of chamfering 3, is conducive to the easier entrance milling cylinder of underground fish internal, and
Interior cutting will not be produced by entangling after fish, provided with three chip areas 4 on the milling shoe 7, be conducive to rock during set milling
Bits fully discharge, so that more efficiently set milling underground fish head is reached, while reducing broken landwaste and the mill teeth that drops to fish head
Secondary abrasion.
Wherein, three angles of chip area 4 on the milling shoe 7 are 120 degree, are conducive to during set milling that landwaste is abundant
Discharge, so that more efficiently set milling underground fish head is reached, while reducing broken landwaste and the mill teeth that drops to the secondary of fish head
Abrasion.
In addition, the chamfering on the milling shoe 7 forms the gradient with milling cylinder 6, interior cutting will not be produced by entangling after fish, protection falls
Fish structural integrity, and be conducive to underground fish is easier to enter set milling apparatus.
It is preferred that, at the top of the mill teeth and outside goes out sword, top mill teeth and outgoing sword milling stratum when fish head is entered in set milling,
Under the support of interior chamfering, milling shoe gradually leaves fish, adds milling shoe inner wall smooth and without cutting function, so can effectively protect
Shield fish is not damaged.
It is preferred that, it is described to design different specifications and models according to actual needs the fish of various different sizes is entered with realizing
Row set milling operation, prevents from damaging fish body in set milling.
The utility model is effective to carry out effective salvaging to underground fish, while the viscous bit freezing of inhaling of easier solution is caused
Down-hole accident, milling shoe bottom is provided with the chamfering that interior light-metering is slided, and it is in certain gradient be connected with body, is effectively protected underground
Fish is not by broken landwaste and secondary abrasion of the mill teeth to fish head of dropping, and milling shoe has three chip areas, and angle is 120 degree, is had
What is imitated solves the slower phenomenon of drilling depth caused by the earth cuttings accumulation that milling is fallen, so as to reach more efficiently set milling underground fish
Head, while reducing broken landwaste and secondary abrasion of the mill teeth to fish head of dropping.
It is described above, only it is preferred embodiment of the present utility model, any those skilled in the art may profit
Equivalent technical scheme is changed the utility model or is revised as with the technical scheme of above-mentioned elaboration.Therefore, foundation
Any simple modification or substitute equivalents that the technical solution of the utility model is carried out, belong to the greatest extent what the utility model was claimed
Scope.
