Description
Technical field
The utility model belongs to OFME field, and it is spiral two-way with brill expansion reaming tool to be related to three sections of one kind.
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 can not meet the authentic and valid collection construction of geologic information during well logging, therefore, short remove must be taken in wellbore construction
Bore, drifting reaming, reaming hole, or even the technical measures such as leak stopping, this will have a strong impact on drilling well timeliness.How prevention is allowed to avoid underground
The generation of complex accident, it has also become the practical problem that each drilling company faces, also all going into overdrive research and develop newly
Technique, new tool.Three sections it is spiral it is two-way expand reaming tool with drilling tool tripping in boring, instrument wing the borehole wall can be carried out expansion and
Finishing, eliminates the flow chart of finishing drilling drifting, substantially increases drilling efficiency.Scene is answered more with brill reaming tool at present
All it is the isometrical wing of the relatively simple straight rib of structure, the moment of torsion that wing is born is big, and the risk that wing is twisted off is high, and using effect is not
It is good.Need that the wing of reaming tool is further improved.
The content of the invention
It is spiral two-way with brill expansion reaming tool, the current isometrical knife of solution that the purpose of this utility model is to provide three sections of one kind
The problem of moment of torsion that the wing of 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：A kind of three sections spiral two-way with expansion reaming tool is bored, and wraps
Main body, box, pin thread and wing are included, the upper and lower ends of main body are respectively box and pin thread, and body outer wall is circumferentially equipped with wing；Institute
The wing stated is divided into three groups, and every group four, the inclination between the circumferential uniformly arrangement in the shape of a spiral of body outer wall, adjacent blades is pressed from both sides
Angle 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 ° to fall
Angle, the external diameter of middle one group of wing are more than the external diameter of the two groups of wings in both sides.
Further, 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, a kind of three sections spiral two-way with brill expansion reaming work
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 all
It is exactly to cut stratum to the effect equipped with wing 4, wing.Described wing 4 divides for three groups, every group four, in the outer wall of main body 1 week
To uniformly arrangement in the shape of a spiral, the slanted angle between adjacent blades 4 is 90 °, in main body periphery between adjacent two groups of wings 4
Windup-degree be 45 °, the upper and lower ends of wing 4 have 30 ° of chamferings, and the external diameter of middle one group of wing 4 is more than two groups of both sides knife
The external diameter of the wing 4.Three groups of wing work external diameters are designed to conical distribution small in ends broad in the middle, can reach the effect of layered cutting.
In order to increase the wear resistance of wing, the described surface of wing 4 studs with alloy block and alloy bar.
In use, wing is expanded and repaired to the borehole wall, eliminates the flow chart of finishing drilling drifting, carries significantly
High drilling efficiency；Three groups of wing work external diameters are designed to conical distribution small in ends broad in the middle, D1<D2, during drilling, bottom is small
Footpath wing first carries out borehole wall internal layer cutting, and as drilling tool moves down, footpath wing broad in the middle cuts the borehole wall again, and achievable layering is cut
To cut, both improved borehole wall cutting quality, reduce the torsional forces that wing is born again, blade surface studs with alloy block and alloy bar,
Ensure smoothly cut stratum during the serious undergauge of well.
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 12 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, after finishing drilling acts instrument, three sections are spiral two-way with brill
Mud drum phenomenon does not occur for reaming tool.In back reaming test construction, also achieve good effect, down hole problem with it is similar
Type well is compared to reduction 100%.Using in 6 mouthfuls of wells of single bend PDM plus PDC drill bit compound drilling, short 400- is taken using instrument
500m progress electrical measurements, electrical measurement one-time success rate 100%, effectively shorten well construction period and cost.
