Embodiment
In helicoid hydraulic motor technical field, screw rod is head end or front end in the front of drilling direction, and correspondingly, the other end is
Tail end or rear end, thus, in orientation, clearly limited for helicoid hydraulic motor with front and rear end to end, meanwhile, on helicoid hydraulic motor
Accessory be also end to end or front and rear to be limited by this on this condition.
In addition, helicoid hydraulic motor is also based on rotating the lead plug realized, thus, it is adaptable radially, axially, it is circumferential be with
Drilling direction or rotor 1, housing 2 are limited.
Structure shown in Fig. 1 is a kind of basic structure of orientation reaming hole screw rod, and rotor 1 is used for connecting screw drilling tool in figure
Motor, there is provided lead plug power, housing 2 all can be parts immovable in the circumferential with screw drilling tool motor one.
The spiro rod section assembling structure of rotor 1 and shell 2 is not shown in Fig. 1, rotor 1 generally has multi-head spiral, forms spiral shell
Bar, the inner surface of shell 2 is the face of cylinder, so as to which the inner surface of multi-head spiral and shell 2 cooperatively forms multiple spiral sealings
Chamber, for conveying mud.In bit part, via the endoporus of rotor 1, i.e. mud hole 5 exports the mud conveyed from annular seal space.
The centralizer 3 being arranged on housing 2 is thus and immovable in the circumference of housing 2.
3 rightings of centralizer are reaming hole knives 4, for ensureing the posture of reaming hole knife 4, the orientation for reaming hole knife 4 in other words.
Lead plug needs cutting fluid, and cutting fluid main component is water, and the mixture of various chemical industry cutting fluids and water is referred to as mud
Slurry, is pumped out mud using slush pump, and the arrow from left to right in Fig. 2 in mud hole 5 represents the direction that mud pumps out.
Pumping pressure is not considered even, and the mud column for going deep into stratum also has very big mud pressure, so as to the He of centralizer 3
It is more stable that reaming hole knife 4, which presses the holding of realized expansion state based on mud,.
Rotor 1 is to provide the part of cutting power, for the power connector of reaming hole knife 4 and driller motor, the wherein rotor 1
The endoporus of (outside screw portion) part is the mud hole 5 for conveying mud, as shown in Fig. 2 for passing through mud to drill bit
The conveying of side.
Configure shell 2 simultaneously, comparatively shell 2 does not rotate, in other words be circumferentially it is static, typically and rotor
1 forms rotation connection, such as the connection formed by bearing 8.Comparatively, shell 2 forms stator, i.e., relative to rotor 1
It is fixed setting.
As illustrated in fig. 1 and 2, stator is the carrier of centralizer 3, for the orientation of reaming hole knife 4, thus, it is needed in well
Upper reliable location, as described in the background section, if using the centralizer 3 of radially fixed structure, with cutting for reaming hole knife 4
Cut, well can expand, and the orientation of centralizer 3 declines.
In the present invention, centralizer 3 is still arranged on shell 2, but its wiper block 31 is set using floating, i.e., can be with
The expansion of well its overall diameter of axle (the equivalent diameter of axle) and also become big.
Specifically, centralizer 3 is radially arranged guide hole 36, such as 4 guide holes 36 shown in Fig. 1 and 2 with multiple, these
Guide hole 36 needs to connect with mud hole 5.
Because the basic structure of shell 2 and rotor 1 is the structure of coaxial line assembling, therefore, the guide hole 36 being radially arranged, lead to
Connection with mud hole 5 can be realized by crossing radial hole.
Due to shell 2 relative to rotor 1 circumferentially be it is static, therefore, can guide hole 36 be distributed circumference on, outside
The inwall of shell 2 opens up an annular groove, and the annular groove is used for the connection of all guide holes 36.
Correspondingly, the position corresponding to annular groove on rotor 1 opens up some side openings, forms annular groove and the connection in mud hole 5,
So as to form the connection of hydraulic channel 32 in the stationary member and dynamic component of rotary pair.
Structure where guide hole 36 is configured to cylinder body, and a piston 35 is set for each guide hole 36, so as to work as slush pump
To start working, mud right side in mud hole 5 from figure pumps out to the left, and the mud with certain pressure intensity flows into hydraulic channel 32,
Promote centrifugation side movement of the piston 35 to guide hole 36.
Due to wiper block 31 be arranged on piston 35 on, then wiper block 31 is just provided with outwardly directed ability, i.e., to from
The ability of heart side movement, generally speaking, open configuration is now in into centralizer 3.As previously described, because mud pressure ratio is higher,
The centralizer 3 of opening has relatively steady state.
Certainly, the range of wiper block 31 needs to be limited, and floating is belonged in its impulse stroke, so as to adapt to difference
The well of diameter, thus there is extraordinary adaptability.
For reaming hole knife 4, using the setting similar with centralizer 3, it cuts wing 41 and set using floating, but different
In the setting of centralizer 3, cutting wing 41 belongs to cutting members, under the promotion of mud pressure, can reach stopping for its impulse stroke
Point, that is, centrifuge side stop, it doesn't matter float the problem of.
Specifically, reaming hole knife 4 is arranged on the head end of rotor 1, and right-hand member as shown in Figure 2, referring to accompanying drawing 5, reaming hole knife 4 has
Multiple guide holes 46 for being radially arranged and being connected with the mud hole 5, the set-up mode of guide hole 46 and guide hole 36 difference, but from
The application of mud pressure is above identical, i.e., is released by mud pressure by wing 41 is cut, allow reaming hole knife 4 to be in open configuration.
The principle of institute's foundation is also identical, is all to use piston structure, such as the piston 45 shown in Fig. 5, piston 45
Piston structure is formed with guide hole 46.
In the state of spudding in, mud pump work, with the beginning of cutting, cutting wing 41 presses the bar for promoting piston 45 in mud
Under part, expansion (reaches centrifugation stop) in place, carries out reaming hole operation.
Now, well is extended the degree adaptable with cutting wing 41, if centralizer 3 is fixed setting, it is propped up
Support can be limited by bigger, and in the structure shown in Fig. 3, mud pressure can promote piston 35 wiper block 31 is extrapolated (from
Heart side), centralizer 3 is reliably supported on the borehole wall.
In the limit travel of wiper block 31, its expansion changes with the size of well, thus has good adaptation
Property, there is the orientating function in different wells in other words.
Mud pressure has been used due to clever structure as Figure 1-5, without setting special hydraulic dilatation equipment,
It is relatively easy to manufacture and design.
During withdrawing, stop boring, slush pump is also no longer worked, and the wiper block 31 on centralizer 3 is resetted by the effect of external pressure
Or be forced to reset, the cutting wing 41 on reaming hole knife 4 is also resetted by the effect of external pressure or is forced to reset, not only
Easily exited from well, and cut wing 41 and retract, it is not easy to damage well.
Because mud pressure ratio is higher, therefore, reaming hole knife 4 can keep stable expansion posture.Meanwhile from processing difficulty or ease journey
Seen on degree, it is also desirable that the expansion structure of cutting wing 41, which is used with the identical structure of expansion structure of wiper block 31,.
I.e. hydraulic channel 32 and hydraulic channel 42 all directly use radial hole.
In some preferred embodiments, although difficulty of processing increases, the expansion of more stable reaming hole knife 4 can be obtained
Open posture.In the structure shown in Fig. 2, hydraulic channel 42 is not to use simple radial hole, but by its import lateral deviation backward
Put, outlet then with the coaxial line of guide hole 46.Referring to Figure of description 2, the head end aperture of visible reaming hole knife 4 is bigger in figure, at this
For the junction portion of reducing, mud pressure is relatively small, and because reduced diameter portion mud presses shakiness, fluctuation is bigger in other words,
The job stability of cutting wing 41 can be influenceed.Therefore, biased backward using by hydraulic channel 42, advantageously ensure that cutting wing
41 job stability.
Specifically, first with the second guide hole coaxial line is included for connecting mud hole 5 and the hydraulic channel 42 of guide hole 46
Part and Part III that is parallel with Part I and being arranged on the rear side of reaming hole knife 4 and connected with mud hole 5, and in rotor 1
The Part II of Part I and Part III is axially connected, three parts are used by the concrete form of hydraulic channel 42
Straight hole, beneficial to processing, and can be effectively rearmounted by the import of hydraulic channel 42, make the stability of mud pressure relatively good, so that
The stability that cutting wing 41 extends out state is relatively good.
By on-the-spot test, the length of Part II is 12 with the draw ratio of the diameter of mud hole 5:When 1 or so, expanded
Wellbore surface quality is preferable, can land used, the length of Part II and the draw ratio of the diameter of mud hole 5 are 10:1~16:1, be still
Selection can be used, it is clear that when draw ratio is relatively small, difficulty of processing is smaller, and when major diameter is bigger, the stability of reaming hole knife 4 can be more
It is good, but the import selection flexibility of hydraulic channel 42 on this condition can be poor.
Further, since reaming hole knife 4 is directly installed on rotor 1, thus returned without the concern for hydraulic channel 42 on centralizer 3
The problem of being connected under the conditions of turning, thus its difficulty of processing is relatively small.
As it was noted above, in certain embodiments, wiper block 31, cutting wing 41 can be answered by external pressure
Position, i.e., move to the centripetal side of corresponding guide hole 36, guide hole 46, in order to be more beneficial for withdrawing, the both ends of wiper block 31 and cut
The both ends of the sharpener wing 41 are equipped with chamfering, and this kind of structure is advantageous to wiper block 31 and cuts the return of wing 41, and also favourable
In reaming hole screw rod from exiting in well.
