Description
Technical field
It the utility model is related to a kind of internal cutting that is oriented to and be segmented junk mill.
Background technology
Sand, i.e. landwaste can be produced in drilling process；After Shale Shaker sieve separation, natural sediment is in Shale Shaker
Following cesspool edge is sieved, because the mobility of sand is poor, it is difficult to be discharged at a distance.For using water wisely, drilling team upper one
As do not allow to go sand washing with water, if going sand washing with water, wasting great lot of water resources, while increasing drilling cost, also producing
Raw substantial amounts of drilling waste water, new pollution can be caused to environment.So the sand to get off from vibratory sieve, most of all to accumulate
Below mud vibrating screen, more heap is higher, influences to produce.In order to not influence to produce, it has to adopt manual cleaning sand.Winter
Construction, if sand shovel is fallen not in time, the ice cube of long duration that is frozen into can not just shovel at all, would have to employ excavator
Dig, for roustabout, shovel sand is also most dirty most bitter also most tired one not only into the thing necessarily made in work
Thing.The prospect pit of a bite 5000m or so, from spudding in completion, it will be about producing hundreds of tons of sand.Work people is not only aggravated
The labor intensity of member, also reduces operating efficiency, directly affects being normally carried out for drilling well work.
A kind of association area for being oriented to internal cutting segmentation junk mill and belonging to oil-well drilling equipment structure design of the present invention,
It is a kind of for carrying out sidetracking operation in sleeve pipe to be oriented to internal cutting segmentation junk mill, is also used for perforated casing, the ground of milling payzone
The loose joint of pipeline and old sleeve pipe are oil drillings with a kind of tubular articles cutting tool by new small casing admittedly in the earth formation
Single independent parts in device systems, this guiding internal cutting segmentation junk mill improved structure, except having in terms of structural strength
Outside larger lifting, its processing effect, service life have a distinct increment.
Utility model content
The shortcomings that the purpose of this utility model is to overcome prior art, there is provided a kind of structural strength is high, processing effect is good,
The guiding internal cutting segmentation junk mill of service life length.
The purpose of this utility model is achieved through the following technical solutions：One kind is oriented to internal cutting segmentation junk mill, and it includes
Top connection, gear cap, spring base, knife cylinder, push rod, sharpening and lower contact, top connection is interior to be provided with cavity, and gear cap is arranged on a left side for push rod
End, gear cap are provided with flow nipple, and gear cap is also coordinated by seal stopper ring and spring base, and spring base coordinates with knife cylinder to be installed, spring
Multiple springs are installed between seat and knife cylinder, knife cylinder is provided with sharpening groove, and sharpening, the blade middle part of sharpening are provided with sharpening groove
With the right-hand member tip contacts of push rod, lower contact is sleeved on the right-hand member of knife cylinder.
Further, described lower contact, which is provided with, is used to ensure lower contact and the supporting positive cover of knife cylinder installation site.
Further, described sharpening is arranged on knife cylinder by pin.
Further, sealing ring is provided between described gear cap and seal stopper ring.
Further, the left end of described flow nipple is provided with back-up ring, and back-up ring is arranged in gear cap and and flow nipple cooperation peace
Dress.
The utility model has advantages below：
1. structural strength is high：This guiding internal cutting segmentation junk mill is compact-sized, and structural strength is high；
2. processing effect is good：The utility model is applied to the technology of the related components structure design of oil-well drilling equipment
Field, can be good with more convenient progress oil drilling processing, processing effect with the equipment；
3. service life is grown：The defects of traditional segmentation junk mill is due to selection and structure design, cause to be segmented the whole of junk mill
Body life time is very limited, and the utility model then overcomes the problem of existing, and service life is greatly improved.
