One kind be the utility model is related to formula Spiral borehole dressing tool, including main body, box, pin thread and wing is bored, the upper and lower ends of main body are respectively box and pin thread, and body outer wall is circumferentially equipped with wing；Described wing is divided into two groups, and every group four, the slanted angle between the circumferential uniformly arrangement in the shape of a spiral of body outer wall, adjacent blades is 90 °, and the windup-degree between adjacent two groups of wings in main body periphery is 45 °, and the upper and lower ends of wing have 30 ° of chamferings.The utility model straight rib wing existing to reaming tool is improved, arrangement, angle to wing have carried out careful design, both the moment of torsion that wing is born had been reduced, reduce wing and twist off risk, improve borehole wall stock-removing efficiency again, reduce down-hole accident risk, simultaneously, spiral wing structure is consistent with drilling fluid flowing in well, reduces flow resistance, while can prevent from forming mud drum on drilling tool.
Description
Technical field
The utility model belongs to OFME field, is related to a kind of with brill formula Spiral borehole dressing tool.
Background technology
As oil-gas field development difficulty progressively increases, well type and stratum also become to become increasingly complex, and shallow-layer undergauge, annular space are suppressed
The complex situations such as pressure, leakage take place frequently.During especially with the drilling tool compound drilling of single bend PDM and PDC drill bit, caused by spiral
Well is very big to later stage well logging construction infection, can not authentic and valid collection logging geological data.Therefore, it is necessary in wellbore construction
Short trip, drifting reaming, reaming hole, or even the technical measures such as leak stopping are taken, this will have a strong impact on drilling well timeliness.How to allow pre-
The anti-generation for avoiding underground complex accident, it has also become the practical problem that each drilling company faces, also all going into overdrive to be ground
Study carefully and develop new technology, new tool.Can be to spiral borehole wall level with drilling tool tripping in, spiral wing with formula Spiral borehole dressing tool is bored
The conventional borehole wall is expanded and repaired, and eliminates the flow chart of finishing drilling drifting, substantially increases drilling efficiency.Scene should at present
More common well reaming tool is all the relatively simple straight rib wing of structure, can not effectively repair the spiral borehole wall.Need pair
The wing of reaming tool is further improved.
The content of the invention
The purpose of this utility model is to provide a kind of with brill formula Spiral borehole dressing tool, the knife of the current isometrical wing of solution
The problem of moment of torsion that the wing is born is big, and the risk that wing is twisted off is high.
The utility model is achieved through the following technical solutions：It is a kind of with boring formula Spiral borehole dressing tool, including main body,
Box, pin thread and wing, the upper and lower ends of main body are respectively box and pin thread, and body outer wall is circumferentially equipped with wing；Described knife
The wing is divided into two groups, every group four, is circumferentially uniformly arranged in the shape of a spiral in body outer wall, the slanted angle between adjacent blades is
90 °, the windup-degree between adjacent two groups of wings in main body periphery is 45 °, and the upper and lower ends of wing have 30 ° of chamferings.
Described blade surface studs with alloy block and alloy bar.
Using the good effect of above-mentioned technical proposal：The utility model straight rib wing existing to reaming tool changes
To enter, the arrangement, angle to wing have carried out careful design, have both reduced the moment of torsion that wing is born, and reduce wing and twist off risk,
Borehole wall stock-removing efficiency is improved again, reduces down-hole accident risk, meanwhile, spiral wing structure and drilling fluid mobile phase in well
Symbol, flow resistance is reduced, while can prevent from forming mud drum on drilling tool.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 main body, 2 boxes, 3 pin threads, 4 wings.
Embodiment
The technical solution of the utility model is described further below in conjunction with the accompanying drawings, but should not be construed as to this practicality
New limitation：
Fig. 1 is structural representation of the present utility model, as illustrated, it is a kind of with brill formula Spiral borehole dressing tool, including
Main body 1, box 2, pin thread 3 and wing 4, the upper and lower ends of main body 1 are respectively box 2 and pin thread 3, and the outer wall of main body 1 is circumferentially equipped with
Wing 4；Described wing 4 is divided to for two groups, every group four, inclining between the circumferential uniformly arrangement of the outer wall of main body 1, adjacent blades 4
Oblique angle is 90 °, and the windup-degree between adjacent two groups of wings 4 in main body periphery is 45 °, and the upper and lower ends of wing 4 have
30 ° of chamferings.Blade contour is designed to the spiral shape being consistent with flow of fluid, reduces flow resistance, while avoids wing root from producing
Mud drum.The design of spiral wing structure, wing is improved to conventional well and Spiral borehole stock-removing efficiency, reduces down-hole accident wind
Danger.
In order to increase the wear resistance of wing, the described surface of wing 4 studs with alloy block and alloy bar.
In use, will be directly connected to formula Spiral borehole dressing tool is bored on drilling tool, while drilling well, rotation
Wing the borehole wall can be expanded and be repaired, during drilling well, the segmentation sped structure of this instrument is advantageous to drilling fluid in drilling tool
With hole annulus internal circulation flow, prevent from forming mud drum on drilling tool, and wing has the function that to be ground and cut, can be effective
The conventional borehole wall and the unnecessary sandstone of the spiral borehole wall are repaired, is avoided that lower brill is obstructed, and ensure that log data effectively gathers.
The utility model straight rib wing existing to reaming tool is improved, and the arrangement, angle to wing have carried out essence
Really design, had both reduced the moment of torsion that wing is born, and had reduced wing and twist off risk, improved borehole wall stock-removing efficiency again, reduced well
Lower accident risk, meanwhile, spiral wing structure is consistent with drilling fluid flowing in well, reduces flow resistance, while can prevent from boring
Mud drum is formed on tool.
The utility model applies 16 mouthfuls of wells in the drilling well block co-occurrence field that undergauge easily occurs, and is not sent out during wellbore construction
Raw undergauge, build the pressure, bit freezing phenomena such as, the process that eliminates short reaming is spiral two-way to draw with boring to expand after finishing drilling acts instrument
Mud drum phenomenon does not occur for eye instrument.In back reaming test construction, good effect is also achieved.Down hole problem and same type
Well, using in 6 mouthfuls of wells of single bend PDM plus PDC drill bit compound drilling, short 400- is taken using instrument compared to reducing 100%
500m progress electrical measurements, electrical measurement one-time success rate 100%, effectively shorten well construction period and cost.
