Description
Technical field
The present invention relates to oil drill equipment technical field, a kind of particularly hydraulic rotary drill-following reamer.
Background technique
In each task of petroleum exploration and development, drilling well is played a very important role.With Shallow Oil-Gas resource
Exhaustion, drilling well industry are gradually marched to Deep Oil And Gas Exploration resource.Deep well hard formation, super hard-rock layer and high abrasive stratum drilling well, at
For worldwide, generality problem.
The stratum that deep drilling is encountered is hard, rock is fine and close, and the amplification degree very little of hole diameter, wellbore gradually forms tapered well
Eye；In drilling process, due to factors such as depth, drill bit often deviates designed track, and the bore side wall drilled out is simultaneously
It is unsmooth, it is uneven, it is deep mixed, a series of drilling well later period operations such as trip-out, setting of casing, well cementation in drilling process are produced
Life seriously affects.
Summary of the invention
The present invention provides a kind of hydraulic rotary drill-following reamer, makes turbine rotation using drilling fluid impulse turbine blade,
The PDC combined cut piece cutting borehole wall surface inlayed outside turbine is driven, keeps the borehole wall smooth, reduces drilling well later period task difficulty.
In order to achieve the above object, the present invention provides a kind of hydraulic rotary drill-following reamer, it is provided with groove in drilling rod lateral wall,
Hollow connecting shaft is fixed in groove by sunk screw, and hollow connecting shaft is connected to the drilling fluid runner inside drilling rod；Turbine
It is sleeved in the middle part of hollow connecting shaft, circumferentially arranged for interval has PDC combined cut piece to turbine outer wall；Positioned at the hollow of turbine both ends
Connecting shaft outer wall is separately installed with sealing bearing；It is close that hollow connecting shaft outer wall between two sealing bearings is set with rotary shaft
Sealing.
Further, reamer is arranged symmetrically along drilling rod cross-sectional periphery.
Further, PDC combined cut piece is 5-17, parallel with axial turbine.
Further, it there also is provided gasket seal between hollow connecting shaft and the groove of drilling rod side wall.
Further, rotation shaft seal is turning quality rubber seal, between turning quality rubber seal and turbo blade
Distance be 3-5mm.
The beneficial effects of the present invention are: make turbine rotation using drilling fluid impulse turbine blade, drives edge outside turbine
Embedding PDC combined cut piece cuts borehole wall surface, keeps the borehole wall smooth, reduces drilling well later period task difficulty, and structure is simple, improves and bores
Well efficiency.

Specific embodiment
With reference to embodiment, the embodiment of the present invention is furthur described in detail.Following embodiment is used for
The present invention is illustrated, but is not intended to limit the scope of the invention.
As shown in Figure 1, a kind of hydraulic rotary drill-following reamer, groove, the hollow company are provided on 1 side wall of drilling rod
Spindle 7 is fixed in groove by sunk screw 6, and the hollow connecting shaft 7 is connected to 1 inside drilling fluid runner of drilling rod, makes to bore
Well liquid passes through hollow connecting shaft 7；The turbine 5 is sleeved on hollow connecting shaft 7,5 outer wall of turbine circumferentially arranged for interval
There is PDC combined cut piece, PDC combined cut piece 4 is embedded on 5 outer wall of turbine 5-17 by welding in this example, and PDC is compound to be cut
Chipping, 4 directions are axial parallel with turbine 5, and 5 blade of drilling fluid impulse turbine makes its rotation, drives external PDC combined cut piece 4
Rotation cuts borehole wall surface, keeps the borehole wall smooth；7 outer wall of hollow connecting shaft positioned at 5 both ends of turbine is separately installed with sealing
Bearing 8；7 outer wall of hollow connecting shaft being located between two sealing bearings 8 is set with rotation shaft seal 3, and both rotary shaft was close
3 outer wall of sealing connects 5 inner wall of turbine, and 3 inner wall of rotation shaft seal connects 7 outer wall of hollow connecting shaft；Rotation shaft seal 3 is simultaneously
Setting two, contacts with two sealing bearings 8 respectively.
The rotation shaft seal 3 is turning quality rubber seal, prevents drilling fluid from revealing；Turning quality rubber seal with
The interlobate distance of turbine 5 is 3-5mm, guarantees the normal work of 5 blade of turbine, reduces the damage of turning quality rubber seal.
It there also is provided gasket seal between the hollow connecting shaft and the groove of drilling rod side wall, guarantee whole leakproofness.
5 direction of rotation of turbine is identical as 1 direction of rotation of drilling rod.
As shown in Fig. 2, the reamer is arranged symmetrically along 1 cross-sectional periphery of drilling rod, two are arranged in this example, can also be arranged
Four.
Working principle of the present invention is as follows:
Drilling fluid enters reamer by the runner in drilling rod 1, is then separately flowed into the turbine 5 of two sides by runner,
PDC combined cut piece 4 outside the blade drive of drilling fluid impulse turbine 5 rotates, and cuts the borehole wall, keeps the borehole wall smooth, drops
Low drilling well later period task difficulty improves drilling efficiency.
