Description

Technical Field

[0001] The invention relates to the technical field of mining measurement, in particular to a wired while-drilling measurement device for mining. Background Art

[0002] The wired MWD device for mining is a measuring device installed near the drill bit. It moves down with the drill bit for measurement, and then transmits the detection data to the corresponding display above the ground through wired transmission, so as to adjust the drilling angle of the drill bit in time. The existing wired MWD device for mining cannot effectively reduce the vibration generated during the drilling process (mainly lateral vibration). The vibration will have a certain impact on the use accuracy of the components inside the measuring device. Especially during the drilling process, when the drill bit encounters hard stones, the speed of the drill bit will automatically decrease under automatic adjustment. At this time, the vibration will increase significantly, which will have a greater impact on the measurement accuracy. Therefore, we propose a wired MWD device for mining to solve the above problems.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Reference Figure 1-Figure 14 A wired measurement while drilling device for mining includes a non-magnetic drill collar 1 fixed between a drill rod 2 and a drill bit 3. The non-magnetic drill collar 1 is a hollow setting with two ends connected, which is used to cooperate with the normal use of drilling flushing fluid. The inner wall diameter can be set to be the same or different from the inner diameter of the drill rod 2, but is preferably set to be the same size; the non-magnetic drill collar 1 includes a plurality of measuring elements 9, and the plurality of measuring elements 9 can perform different required measurements respectively. For example, the measuring elements can be pressure sensors, temperature sensors, resistivity sensors, etc., which are specific prior arts and are not specifically elaborated here; at the same time, the non-magnetic drill collar 1 is usually made of an alloy material that does not contain iron elements or has a very low iron content, so that it can be ensured that it is not disturbed by the magnetic field during operation, which is convenient for the measuring element 9 to perform better measurements.

[0019] The non-magnetic drill collar 1 is provided with a plurality of mounting cavities 4 which cooperate with the measuring element 9, and two annular seats 5 are fixedly installed in each mounting cavity 4, and two mounting blocks 7 are installed on the two annular seats 5 through elastic protective components, a mounting plate 8 is fixedly installed between the two corresponding mounting blocks 7, and the measuring element 9 is fixedly installed on the corresponding mounting plate 8, and an airbag body 11 is fixedly installed on each mounting block 7, and the airbag body 11 cooperates with the corresponding elastic protective component; the setting of the elastic protective component can directly play a vibration reduction and protection effect when the overall device has a certain vibration, and at the same time, when the resistance of the drill bit 3 increases, the protection effect is further improved by cooperating with the airbag body 11.

[0020] The elastic protective component includes an annular airbag 6 and a connecting pipe 10. An annular airbag 6 is fixedly installed on the inner wall of each annular seat 5. The annular airbag 6 and the airbag body 11 can be made of materials such as fluororubber, silicone rubber, nitrile rubber, etc. Such materials have good high temperature resistance, corrosion resistance, strong pressure resistance and good sealing performance, and can better meet the use of complex environmental conditions underground; in the initial state of the annular airbag 6, it is arranged in the middle position of the corresponding annular seat 5, and the overall initial thickness is less than or equal to the thickness of the annular seat 5; a plurality of connecting pipes 10 are fixedly installed between the two annular airbags 6 located in the same installation cavity 4, and the setting of the connecting pipe 10 forms a connecting part between the two annular airbags 6 located in the same installation cavity 4, At the same time, the multiple connecting tubes 10 in the same installation cavity 4 are distributed in a circumferential array, and the connecting tube 10 is inclined between the corresponding two annular airbags 6. The connecting tube 10 can be made of soft or hard materials. When using soft materials, materials with a certain elastic strength are preferred, so that the connecting tube 10 can also produce a certain supporting effect between the two annular airbags 6 to a certain extent; further, a plurality of arc-shaped vibration-damping springs can be fixedly arranged between the annular seat 5 and the corresponding installation block 7. The arc-shaped vibration-damping springs can improve the overall vibration-damping effect on the one hand, and can also increase the stability of the device when it is used to a certain extent; or a plurality of telescopic rods can be fixedly arranged along the circumferential array between the annular seat 5 and the corresponding installation block 7 to increase the stability when it is used; Reference Figure 1-Figure 14 The lower surface of each airbag body 11 is fixedly connected with multiple connecting pipes 12, and the lower end of the connecting pipe 12 is connected with the corresponding elastic protective component (specifically connected with the corresponding upper annular airbag 6, and multiple mounting blocks 7 located above are provided with multiple through holes that match the connecting pipe 12). When the airbag body 11 is subjected to a certain pressing force, part of the gas inside it will enter the upper airbag body 11 through the connecting pipe 12, and at the same time, under the action of the connecting pipe 10, it will also enter the lower airbag body 11, thereby better protecting the corresponding measuring element 9 in the lateral direction when the lateral resistance increases.

The centrifugal sliding components are arranged to cooperate with the moving blocks 15 for use. During the normal drilling process, the resistance amplitude of the drill bit 3 is small. At this time, the moving block 15 is completely located in the corresponding motion groove 13 under the action of centrifugal force. When the resistance increases, the rotation speed of the drill bit 3 will decrease. At this time, the centrifugal force on the moving block 15 is reduced, and then part of it moves to the outside of the motion groove 13; The centrifugal sliding component includes a motion groove 13, an elastic component, and a limit component. A plurality of motion grooves 13 are provided on the inner wall of the non-magnetic drill collar 1, and the moving block 15 is slidably installed on the corresponding motion groove 13 through the limit component. The limit component includes a limit slide bar 21 and a strip limit slide groove. Two limit slide bars 21 are symmetrically fixedly installed on each moving block 15. A strip limit slide groove matching the limit slide bar 21 is provided on the inner wall of the motion groove 13; an elastic component is fixedly installed between the motion groove 13 and the corresponding moving block 15; the elastic component is a spring rod 14, and a spring rod 14 is fixedly installed on the inner wall of each motion groove 13, and one end of the spring rod 14 is fixedly set with the corresponding moving block 15.

This is a common existing technology and will not be elaborated on here.

[0022] Reference Figure 1-Figure 14A dynamic and static adjustment protection component is installed between the moving block 15 and the centrifugal sliding component and the corresponding annular seat 5; the dynamic and static adjustment protection component includes a water inlet hole 16, a water inlet pipe 17, a water inlet pipe 2 18, a water outlet pipe 19, an annular groove 20, and a connecting water pipe. The upper end surface of each moving block 15 is divided into an arc setting. When the moving block 15 moves outward when the centrifugal force decreases, the arc portion will move to the outside of the motion groove 13. The arc setting can reduce the impact of the drilling flushing fluid on it when it directly contacts it; each moving block 15 is provided with a plurality of water inlet holes 16, and the water inlet holes 16 are L-shaped. The upper port is opened on the upper surface of the moving block 15, and the lower port is opened on the side that matches the spring rod 14, which is located on the same measuring element 9 The two movement grooves 13 on both sides form a group, one of the movement grooves 13 is fixedly connected to the installation cavity 14 with a water inlet pipe 17, and the other movement groove 13 is fixedly connected to the installation cavity 14 with a water inlet pipe 2 18. The outer wall of each annular seat 5 is provided with an annular groove 20. The non-magnetic drill collar 1 is fixedly connected with multiple water outlet pipes 19, and the water outlet pipe 19 is matched with the annular groove 20 arranged below.

The advantage of this part is that when water flows into the annular groove 20 through the water inlet pipe 1 17 and the water inlet pipe 2 18, the two can accelerate the flow of water. In the figure, the water outlet ends of the water inlet pipe 17 and the water inlet pipe 2 18 are matched with the upper annular groove 20. In the specific setting, the water outlet pipe of the water inlet pipe 2 18 can also be matched with the lower annular groove 20.

The two moving blocks 15 located on both sides of the same measuring element 9 are a group, wherein a driving component is arranged between one of the moving blocks 15 and the non-magnetic drill collar 1, and the driving component includes a limiting sliding cavity 22, a connecting rod 23, and a rack 24. The non-magnetic drill collar 1 is provided with a plurality of limiting sliding cavities 22 and a plurality of circular cavities one, and the circular cavity one is connected with the corresponding motion groove 13 and the limiting sliding cavity 22. A rack 24 is slidably installed in each limiting sliding cavity 22, and a connecting rod 23 is fixedly installed at one end of the rack 24, and one end of the connecting rod 23 passes through the corresponding circular cavity one and is fixedly arranged with the corresponding moving block 15; A plurality of extrusion components are arranged in the non-magnetic drill collar 1, and the extrusion components cooperate with the corresponding airbag body 11. The extrusion components include an extrusion roller 27 and a shaft body 29. A plurality of shaft bodies 29 are rotatably installed in the non-magnetic drill collar 1. A squeezing roller 27 is eccentrically fixed on each shaft body 29, and the squeezing roller 27 cooperates with the airbag body 11 directly below; the difference between the maximum straight-line distance and the minimum straight-line distance between the squeezing roller 27 and the axis of the shaft body 29 is less than the thickness of the airbag body 11, so that when the squeezing roller 27 is in the lowest position, the upper and lower surfaces of the airbag body 11 will not contact each other, ensuring normal use.

[0024] The non-magnetic drill collar 1 is also provided with a plurality of transmission components, and the transmission components cooperate with the corresponding driving components and the extrusion components. The transmission components include a shaft one, a gear one 25, a gear two 26, and a gear three 28. The non-magnetic drill collar 1 is provided with a plurality of mounting cavities two and a plurality of circular cavities two, and the circular cavity two is connected with the corresponding mounting cavity two and the mounting cavity one 4, and one end of the shaft body two 29 passes through the circular cavity two and is rotatably installed in the mounting cavity two, and the mounting cavity two is connected with the corresponding limiting sliding cavity 22, and a shaft one is rotatably installed in the mounting cavity two, and a gear one 25 meshing with the rack 24 is fixedly installed on the shaft one, a gear two 26 is fixedly installed on the shaft one, and a gear three 28 meshing with the gear two 26 is fixedly installed on the shaft body two 29.

[0025] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0026] In the present invention, in a normal use state, the drilling flushing fluid flows normally in the drill rod 2, the non-magnetic drill collar 1, and the drill bit 3. At this time, the moving block 15 is completely located in the moving groove 13, the water inlet 16 is in a completely blocked state (the flushing fluid will not enter the area where the spring rod 14 is located), the annular groove 20 is in a full water state, but the water in the annular groove 20 is in a relatively accurate state, the annular airbag 6 and the airbag body 11 are both in a full air state, and the nearest end of the squeezing roller 27 and the second shaft body 29 is in contact with the airbag body 11; During normal drilling, the resistance changes slightly, the rotation speed is relatively large, and the vibration generated during the rotation process can be directly reduced by the static water in the annular groove 20 and the annular airbag 6 to meet the needs of normal use; When the resistance increases, the rotation speed of the drill bit 3 will decrease, thereby driving the rotation speed of the non-magnetic drill collar 1 to decrease. At this time, the centrifugal force on the moving block 15 is reduced. Under the action of the spring rod 14, the moving block 15 is partially moved to the outside of the moving groove 13. During the movement of the moving groove 13, the rack 24 is driven to move horizontally through the connecting rod 23. During the movement of the rack 24, the gear 1 25 is driven to rotate. The rotation of the gear 1 25 drives the shaft 2 29 to rotate through the cooperation of the gear 2 26 and the gear 3 28. The rotation of the shaft 2 29 drives the squeezing roller 27 to rotate eccentrically (maximum rotation of 180°). The squeezing roller 27 rotates eccentrically to squeeze the airbag body 11, and squeezes part of the gas in the airbag body 11 into the annular airbag 6, thereby increasing the protective effect of the annular airbag 6 within a certain period of time (after the rotation speed returns to normal, the annular airbag 6 and the airbag body 11 return to the initial state. The purpose of this setting is to increase the protective effect in a short time, but to minimize the damage to the annular airbag 6 caused by the over-filled state for a long time); When the moving block 15 moves to the outside of the moving groove 13, the drilling flushing fluid can enter the annular groove 20 through the water inlet hole 16, the water inlet pipe 1 17, and the water inlet pipe 2 18. At the same time, the valve on the water outlet pipe 19 is opened to allow the liquid to flow in the two annular grooves 20, and the initial static protection is adjusted to dynamic protection, thereby further improving the protection effect in the process. The vibration generated by the drill bit 3 during normal drilling is low-frequency vibration. At this time, the vibration reduction effect of static water is better. When the resistance increases, the vibration generated is mostly high-frequency vibration. At this time, the vibration reduction effect of flowing water is better.

[0027] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
