Matter track cylinder mesoporous liquid switch (2), in other words, boreliquid in hard track cylinder mesoporous inner wall cylindrical surface (1), hard track cylinder
Switch (2) and fan-shaped circular tube external wall sector cylinder (3) collectively form mechanical drilling guidance dress in mineral reserve mechanical guide drilling tool
It sets；
For mineral reserve mechanical guide drilling tool, hydraulic end designs four centering edges of processing in attached drawing, can in concrete application
Design three centering edges of processing or five centering edges or six centering edges or multiple centering edges, specifically unite when designing processing
Raise consideration；Hydraulic end centering edge quantity is different, and corresponding liquid switch (2) quantity is different, and mechanical Well drilling guiding device structure is different,
Moreover, identical volumes of liquid switch (2), fan-shaped circular tube external wall sector cylinder (3) opening central angle is different, mechanical drilling guidance dress
It is also different to set structure；When fan-shaped circular tube external wall sector cylinder (3) opening central angle or central angle are more than two liquid of arbitrary neighborhood
Switch (2) angle, and be open central angle be equal to two liquid switch (2) angle half-angle odd-multiples of arbitrary neighborhood when, tool-face become
Change range perseverance is two liquid switch (2) angle half of arbitrary neighborhood, meanwhile, borehole wall reaction force is continuous, continual.
2. a kind of mechanical Well drilling guiding device according to claim 1, it is characterised in that：Utilize mechanical Well drilling guiding device
Multiple centering edge mineral reserve mechanical guide drilling tools can be developed, including mineral reserve machinery vertical drilling tool and mineral reserve machinery increase
Tiltedly, orientation or specific device angle guide drilling tool are turned round；
For mineral reserve mechanical guide drilling tool, multiple centering edges, and processing peace are processed in the circumferential uniformly distributed design of hydraulic end
Fill fluid passage, plunger case, plunger and push plate；Hydraulic end mesoporous installs hard track cylinder, hard track cylinder mesoporous medial surface
For hard track cylinder mesoporous inner wall cylindrical surface (1), cleaner for high-pressure drilling fluid when hard track cylinder mesoporous by forming in hard track cylinder
Hole drilling fluid chamber；Fluid passage from plunger case extends radially inward into hard track cylinder mesoporous drilling fluid chamber and hard
Matter track cylinder mesoporous inner wall cylindrical surface (1) forms hard track cylinder mesoporous liquid switch (2), it is circumferential uniformly distributed and with centering edge direction
Unanimously；The fan-shaped pipe of hard track cylinder mesoporous installation, fan-shaped pipe lateral surface is fan-shaped circular tube external wall sector cylinder (3), fan-shaped
Circular tube external wall sector cylinder (3) diameter is equal to hard track cylinder mesoporous inner wall cylindrical surface (1) diameter, fan-shaped circular tube external wall sector column
Face (3) opening central angle or central angle are more than two hard track cylinder mesoporous liquid switch (2) angles of arbitrary neighborhood, and open circles
Heart angle is equal to two hard track cylinder mesoporous liquid switch (2) angle half-angle odd-multiples of arbitrary neighborhood；Fan-shaped pipe and weighting block
Direction is consistent, and fan-shaped circular tube external wall sector cylinder (3) rotates to hard track cylinder mesoporous inner wall cylindrical surface (1) bottom with fan-shaped pipe
Side and symmetrical, in other words, mechanical Well drilling guiding device tool-face perseverance are 180 °, multiple centering edge mineral reserve mechanical guide drilling wells
Tool is multiple centering edge mineral reserve machinery vertical drilling tools；
If it is direction phase to adjust fan-shaped pipe and weighting block relative position in multiple centering edge mineral reserve mechanical guide drilling tools
Instead or direction is vertical or any other tool face angle, then, multiple centering edge mineral reserve mechanical guide drilling tools translate into more
A centering edge mineral reserve machinery increasing hole angle turns round orientation or specific device angle guide drilling tool.
