Description
Technical field
The utility model is related to petroleum drilling technology field, and in particular to one kind be applied to wear-resisting rock stratum hydraulic rotary with
Bore reamer.
Background technology
In each task of petroleum exploration and development, drilling well plays a very important role.But with Shallow Oil-Gas resource
Exhaustion, drilling well industry gradually marches to Deep Oil And Gas Exploration resource.Deep well hard formation, super hard-rock layer and high abrasive stratum drilling well,
Still global, generality problem till now.In this strata drilling, rate of penetration is slow, shoots a glance at bouncing of drilling tool seriously, straight well
Anti-oblique and well straightening is difficult, and drilling tool accident is more, drill bit, centralizer serious wear, hole diameter problem etc..
Stratum that deep drilling bores chance is hard, rock is fine and close, and hole enlargement ratio very little, drill bit, drill string wear are serious, bores
Head diameter is gradually reduced, and gradually tapered well, the lower brill of next brill are difficult for well；In addition drilling cuttings is in fine-powdered, in rule
Fine and close mud cake is formed on the borehole wall, being bored under PDC drill bit or common centralizer needs long well section reaming, and such case is abnormally dangerous, under
Put drilling tool too soon, drill bit or centralizer are filled in slim-hole and blocked, and thus there will be two kinds of situations：The first situation twists off
Drilling tool or drilling tool rise button；Second of situation shortens after being reversed because of drilling tool, blocks part extraction, but lower drilling string is because of elastic energy
Release drastically rotates, it is likely that causes upper drilling string back-off, threads off, lower most drill string falls well, drill bit and centralizer and pounded
Enter slim-hole bit freezing.Even if by getting into bottom under the measure such as reaming PDC drill bit and common centralizer, being pulled out of hole after drilling can also be stranded
Difficulty, and ligament of trapping is too small, and well cementation pressure is too high.
In drilling process, due to factors such as depth, drill bit often deviates designed track, and the well drilled out is simultaneously
It is unsmooth, it is uneven, deep mixed, i.e. dog-leg severity.These problems are to the trip-out in drilling process, setting of casing, well cementation etc. one
Serial later stage drillng operation influences serious.
In view of the above-mentioned problems, need a set of effective technical scheme badly.
Utility model content
To be analyzed based on more than, the utility model devises one kind and is applied to wear-resisting rock stratum hydraulic rotary drill-following reamer,
The instrument is used as power source by drilling fluid, and drives the pinion rotation of tool interior, and gear drives being revolved from rotary drill for both ends
Turn, consistent with drilling rod direction of rotation from the direction of rotation of rotary drill, spin bit face when the projection of out-of-flatness occurs in the borehole wall
The PDC composite sheets of installation can continue rotary cutting projection rock, make the borehole wall smooth；When trip-out is hampered, pass through upper tool part
Reaming hole head is to hindering position to continue rotary cutting, after the borehole wall is smooth, you can acts drilling tool.
In order to achieve the above object, the utility model adopts the following technical scheme that：
One kind be applied to wear-resisting rock stratum hydraulic rotary drill-following reamer mainly by internal thread, external screw thread, drilling fluid runner,
Formed from rotary drill, gear, drilling fluid eyelet, turbine, plugging device, power transmission shaft, power cavity, sealed bearings and inserted cutting edge.
One kind is applied to wear-resisting rock stratum hydraulic rotary drill-following reamer by internal thread and external screw thread respectively with boring up and down
Well instrument connects, and upper and lower two are arranged on tool body, two spin bit face installation edges from rotary drill by sealed bearings
Tooth cutting edge, the side of inserted cutting edge work stud with PDC composite sheets, install gear from the inside of rotary drill, gear is fixed on
From rotary drill, gear is engaged with from rotary drill inwall tooth；Upper and lower two have four gears respectively from the inside of rotary drill, and
Upper-lower position is identical；Gear of the top from the gear of rotary drill and bottom from rotary drill is by being driven axis connection；Pacify on power transmission shaft
Fill turbine；The space that power transmission shaft is formed with turbine is power cavity；Sealing isolation drilling fluid between power cavity and gear.
Drilling fluid is by internal thread entering tool, and the drilling fluid runner being gradually reduced by space, drilling fluid runner
Diminish the pressure increase caused in drilling fluid runner, and flow velocity is accelerated；Installation plugging device in the middle part of instrument, to the drilling fluid of high-voltage high-speed
Blocked；Four drilling fluid eyelets are had on drilling fluid runner above and below plugging device, four drilling fluid eyelets are same
In plane, two neighboring drilling fluid eyelet is in 90 °, and each drilling fluid eyelet direction is with tool axis direction into 60 °；High-voltage high-speed
Drilling fluid entered by drilling fluid eyelet in power cavity, while high speed impact turbine；Turbine drives line shaft rotation, line shaft
Pinion rotation up and down is driven, the gear of rotation drives spin drill bit quickly to rotate, and the inserted cutting edge for the bit face that spins is over the ground
Layer is cut.
After the drilling fluid of high-voltage high-speed is by power cavity, sprayed by the drilling fluid eyelet of bottom, into drill bit；Told power
Chamber has four, by being designed to turbo blade angle so that gear direction of rotation is consistent, to providing power from rotary drill；
Spinning, bit direction is identical with bit direction, and rotary speed is higher than bit rotation velocity；The phase for the bit face that spins
There is the tool exterior drilling fluid return passage of certain distance between adjacent two inserted cutting edges.
The beneficial effects of the utility model are：(1) it is applied to wear-resisting rock stratum hydraulic rotary with brill expansion by installing one kind
After eye device, upper and lower two from rotary drill simultaneously cutting drilling deep-well wear-resisting stratum when the protrusion borehole wall that occurs, make the borehole wall smooth.(2)
Bit rotation velocity spin faster, cutting effect more preferable (3) up and down two can be in two kinds of situations of creeping into and pull out of hole from rotary drill
Under, the borehole wall is ground, makes the borehole wall more smooth.
