Description
Technical field
The invention belongs to drilling well, exploitation field, be specially intelligent retraction type composite drill bit.
Background technology
Large-size drill is usually used in well-digging, exploitation, oil field, field of opening a mine, as: mining drill bit well drill, high-speed steel drill, rock bit, anchor bit, geological drill bit, recover petroleum drill bit etc.
Because the area of large bit contact target is large, when running into solid bed, rate of penetration is slow, skid, be difficult to location, drill bit is scrapped soon, more bit change frequency is large, thus in work progress, phenomenons such as occurring that boring is difficult, long in time limit, increase cost, increase workman's amount of labour, efficiency is low.
In order to solve above Problems existing, people are seeking a kind of new technical scheme always, overcome the above problems.
Little drill bit, the area of head contact target is little, when running into solid bed, is easier to creep into compared with large drill bit, and accurate positioning.
In recent years, the development of digitizing technique, the development of sensor technology, the manually-operated work of a lot of needs, or the place of artificial inconvenient operation, can control sensor with computer software, then control mechanical work by sensor.
Summary of the invention
The present invention seeks to for the deficiencies in the prior art, utilize digitizing technique, sensor technology, by programme-control size drill bit alternately operating, thus the intelligent retraction type composite drill bit provided.
The technical solution used in the present invention
In order to realize foregoing invention object, the present invention includes: large drill bit, 3 to 20 little drill bits, 3 to 20 retraction electromagnet, control motor, detecting sensor, microprocessor and wiring board, 3 to 20 apertures.
Described large drill bit is provided with 3 to 20 apertures, and aperture is the retraction passage of little drill bit, and little drill sleeve is in aperture.
Described control motor, detecting sensor, microprocessor and wiring board are arranged on the applicable position of large drill bit.
Described little drill bit is identical with the drill bit direction of described large drill bit.
Described detecting sensor carries out hardness determination to bit operation object, the information detected changes the signal of telecommunication into, input microprocessor and wiring board, when the hardness of target is in certain number range, microprocessor and wiring board control large drill bit energising work, after the hardness of target exceedes certain number range, microprocessor and wiring board control little drill bit energising work.
The present invention is before drill bit goes into the well work, the numerical value of large drill bit and little drill bit alternation is determined by operating personnel, namely determine the numerical value of target hardness, control large bit operation under what situation, under what situation, large drill bit quits work, little drill bit starts working.
Beneficial effect of the present invention.
1, large drill bit bradawl head is according to the hardness of target, alternation, overcomes the deficiency existed in the construction of single drill bit.
2, reduce the work difficulty of large drill bit, improve working efficiency and the life-span of large drill bit.
3, intelligentized control method: when not running into hard geological stratification, only needs large bit operation, and when running into hard geological stratification, large drill bit bradawl head just can alternation repeatedly automatically.
3, number of times of going into the well is decreased.
4, add speed of application, reduce construction cost.
5, the diamond bit of same parameter, the present invention can decrease the consumption of diamond raw material.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the present invention is described further.
As shown in Figure 1 and Figure 2, an intelligent retraction type composite drill bit for drilling well, it comprises: large drill bit (1), 3 little drill bits (2), 3 bounce back electromagnet (3), 2.2KW high-speed main spindle motor (4), thermoelectric transducer (5), microprocessor and wiring board (6), 3 apertures (7).
Large drill bit (1) is provided with 3 apertures (7), and aperture (7) is the retraction passage of little drill bit (2), and little drill bit (2) is enclosed within aperture (7).
Large bit central is hollow state.
3 apertures (7) and 3 little drill bits (2) are with positive triangle arrangement.
2.2KW high-speed main spindle motor (4), microprocessor and wiring board (6) are arranged on the center hollow position of large drill bit (1).
Described thermoelectric transducer (5), is arranged in large drill bit (1) body, so that temperature when accurately testing large drill bit (1) operation.
Described 3 little drill bits are identical with the drill bit direction of described large drill bit.
Large drill bit is when boring hard geological stratification, it is larger that temperature raises numerical value, bore comparatively soft geological layer time, it is less that temperature raises numerical value, so temperature when thermoelectric transducer (5) can obtain large bit operation, thus obtain the hardness information data of target, the information detected changes the signal of telecommunication into, input microprocessor and wiring board (6) are checked, analyze, are processed, and processor receives data and performs according to a logic circuit.
When the hardness of target is in certain number range, microprocessor and wiring board (6) control large drill bit energising work, and now 3 little drill bits are retracted within the inside of large drill bit, transfixion.
After the hardness of target exceedes certain number range, microprocessor and wiring board (6) control little drill bit energising work, and large drill bit quits work, transfixion, and 3 little drill bits stretch out from 3 apertures of large drill bit, start working.
After in the complete rock drilling of little drill bit, quit work, be retracted in large drill bit abdomen, microprocessor and wiring board (6) control the energising of large drill bit and start working, at this moment because lithosphere has had three duck eyes, so than being easier to fragmentation.
The present invention is before drill bit goes into the well work, the numerical value of large drill bit and little drill bit alternation is determined by operating personnel, namely determine the numerical value of target hardness, control large bit operation under what situation, under what situation, large drill bit quits work, little drill bit starts working.
When not running into hard geological stratification, only need large bit operation.When running into hard geological stratification, large drill bit bradawl head just can alternation repeatedly.
