Description

Technical Field

[0001] The invention relates to the technical field of rock formation information collection, in particular to a super-hard long drill bit with a tip inlaid with cemented carbide and capable of collecting rock formation information. Background Art

[0002] In the fields of petroleum, geological exploration and mining, drilling operations need to achieve efficient rock breaking and accurate rock formation information collection at the same time, and collect certain samples from ore bodies, surrounding rocks and mine products according to certain specifications. The purpose is to study the quality of minerals, the physical and chemical properties of ores and surrounding rocks, the technical performance of ores and the mining conditions of mineral deposits, etc., to provide information for mineral deposit evaluation, reserve calculation and related geology, mining, mineral processing and comprehensive utilization of minerals. Among them, the drilling method of sampling is to use tunnel excavation blastholes or special sampling holes to collect rock powder and cuttings as samples.

[0003] In the prior art, for example, a PDC drill bit with rock formation information collection function, such as publication number CN116717186A, is provided. By providing crushing blades, rock cuttings are secondary crushed into smaller shapes, and the continuous rotation drives the rock cuttings upward for easy sampling and collection. To facilitate rock cuttings sampling and collection, the above document adopts the provision of sampling chambers and partitions to achieve independent sampling of rock cuttings at different depths while drilling is underway.

[0004] However, in actual use, traditional drill bits find it difficult to collect rock samples while analyzing sample information in real time; and due to the complexity of underground rock formations, even after obtaining the rock formations, the collected rock formations are prone to falling due to gravity, making it impossible to effectively ensure the integrity of the rock formation information.

The combination of the petal-shaped anti-fall component and the storage tube cavity can effectively solve the problem of difficulty in preserving samples when drilling upward, ensure the integrity and accuracy of the rock formation samples, and facilitate subsequent analysis and research.

A connecting shaft 4 is fixedly installed at the center of the center mounting member 32. A drill blade 11 is fixedly installed on the drilling portion of the drill bit body 1. The drilling end of the drill blade 11 is inlaid with multiple diamond composite sheets to enhance the excavation ability in a high temperature environment, improve the stress condition of the cutting edge, and reduce drilling stress.

[0036] A drilling mechanism is used to achieve rock breaking and rock layer sample collection, integrating the functions of efficient rock breaking and rock layer information collection and analysis; in conjunction with the setting of the rock layer collection mechanism, it can effectively prevent the collected rock layer from falling due to gravity, ensuring the integrity and accuracy of the rock layer samples, and facilitating subsequent analysis and research; at the same time, the stabilizing rod mechanism 3 plays a role in stabilizing the drill bit and preventing the upper rock bed from sinking, thereby improving the efficiency and quality of the drilling operation as a whole, and solving the problems that existing equipment is difficult to collect and analyze sample information in real time, and that samples are prone to falling and cannot ensure the integrity of information.

[0037] Example 2, refer to the attached Figure 1-14On the basis of the first embodiment, in order to realize the modular assembly of the rod body 2 and the connection with the drill body 1: the lower conical sleeve 121 and the upper threaded sleeve 122 are integrally formed, the inner ring surface of the lower conical sleeve 121 is fixedly installed with a spiral convex pattern 1211, and the outer ring surface of the lower conical sleeve 121 is threadedly connected to the inner ring surface of the drill body 1; the upper inner ring surface of the lower conical sleeve 121 is provided with a conical groove 1230, and the interior of the conical groove 1230 is fixedly installed with a conical steel plate 123, and the inner ring surface of the upper threaded sleeve 122 is provided with an annular groove 1240, and the inner ring wall surface of the annular groove 1240 is provided with a sensing The ring plate 124 should be provided; the fastener includes a threaded joint 23 and a threaded joint 24. The central inner surface of the combined rod body 1 21 is provided with an embedding groove 210, and the central inner surface of the combined rod body 22 is fixedly installed with a molding 2100. The outer surface of the molding 2100 is movably engaged with the inner wall of the embedding groove 210. The ends of the combined rod body 1 21 and the combined rod body 2 22 are respectively provided with a convex thread 20. The inner surface of the threaded joint 23 is threadably adapted to the outer surface of the convex thread 20 near one end of the thread collection component 12, and the lower inner surface of the threaded joint 23 is threadedly connected to the outer surface of the upper threaded sleeve 122;

[0038] In this embodiment, the combined rod body 1 21 and the combined rod body 2 22 are docked and assembled to form a complete cylindrical rod body, and the internal space is used for storing collected rock samples. When the combined rod body 1 21 and the combined rod body 2 22 are assembled, the embedded groove 210 and the embedded strip 2100 are adapted and engaged to form a seamless splicing of the combined rod body 1 21 and the combined rod body 2 22. The threaded joint 1 23 and the threaded joint 2 24 cooperate to achieve the fastening installation of both ends of the combined rod body 1 21 and the combined rod body 2 22, and it is also convenient for the subsequent collection of rock samples. At the same time, the threaded joint 1 23 serves as a fastener after the combined rod body 1 21 and the combined rod body 2 22 are assembled, and its lower end position is adapted to the upper side thread of the upper threaded kit 122. The threaded collection assembly 12 here is composed of the lower conical kit 121 The structure formed as an integral whole with the upper threaded kit 122 can also ensure that the threaded joint 23 connects the rod body 2 and the drill bit body 1 as a whole in a modular manner, and is easy to disassemble and replace, and has higher practicality; it is worth noting that a spiral convex pattern 1211 is added to the inner annular surface of the lower conical kit 121, which is convenient for rapid sampling and transportation of the rock formation at the sampling port 10, and through the setting of the conical steel plate 123, its surface is made of smooth stainless steel, which contacts the surface of the rock formation, reducing the resistance between the rock formation and the rock formation, and utilizing the setting of the induction ring plate 124 as compensation for the gap in the annular groove 1240, not only the physical properties of the rock formation can be collected, but also the temperature, chemical composition and other information of the rock formation can be obtained in time, providing more comprehensive rock formation data. It should be noted that the induction ring plate 124 is electrically connected to the electric telescopic rod 270.

[0039] Example 3, refer to the attached Figure 1-14On the basis of the second embodiment, in order to avoid the problem that the rock sample collected enters the interior of the rod body 2 and falls due to gravity, affecting the integrity of the sample collection: the storage part is composed of a lower anti-falling part and an upper anti-impact part. The lower anti-falling part includes a compensation support ring 25 and a lower annular seat 251. The compensation support ring 25 is fixedly installed on the inner ring surface of the upper threaded sleeve 122. The lower annular seat 251 is fixedly installed on the upper end of the compensation support ring 25. A card slot 2510 is provided on the upper inner wall of the lower annular seat 251. The inner surface of the card slot 2510 is movably connected to a card plate 262. The upper end of the card plate 262 is movably connected to a wrapping plate 26, the clamping plates 262 and the wrapping plates 26 are provided in multiple groups and arranged in a circular array about the central axis of the lower annular seat 251; the clamping plate 262 is fixedly installed on the lower end of the wrapping plate 26, and the inner wall of the lower annular seat 251 is penetrated by a fixing bolt 263 and is threadedly connected to the inner wall of the clamping plate 262, and the inner wall of the upper end of the clamping plate 262 is fixedly installed with a shaft 2621, and the outer surfaces of the two ends of the shaft 2621 are respectively movably connected to the inner surface of the connecting ear plate 261, and the outer surface of the shaft 2621 is sleeved with a torsion spring 2622, which is arranged between the inner sides of the connecting ear plates 261;

[0040] In this embodiment, the lower anti-falling part is integrated and installed on the inner side of the upper threaded kit 122. When the collected rock sample is transported upward through the sampling port 10, the rock layer breaks through upward. At this time, the multiple groups of wrapping plates 26 are impacted by the rock layer below and swing, so that the multiple groups of wrapping plates 26 forming the wrapping structure are deformed to form a petal-shaped structure. After the rock layer breaks through the wrapping plates 26, it enters the storage tube cavity formed by the combined rod body 1 21 and the combined rod body 2 22. Subsequently, the multiple groups of wrapping plates 26 are gradually retracted toward the center under the elastic force of the torsion spring 2622, forming a semicircular arch structure to prevent the central rock layer sample from collapsing and falling.

[0041] Example 4, refer to the attached Figure 1-14On the basis of the third embodiment, in order to avoid the impact of the rock sample collection on the top of the combined rod body 1 21 and the combined rod body 2 22: the upper anti-impact member includes a parallel connecting rod 27 and an upper ring plate 28. The lower end of the parallel connecting rod 27 is fixedly installed with a lower ring plate 271. The lower side of the lower ring plate 271 is fixedly installed with a claw-shaped contact block 272. The inner surface of the claw-shaped contact block 272 is provided with a clamping convex strip. The claw-shaped contact block 272 is provided with multiple groups and the inner surfaces of the claw-shaped contact blocks 272 are respectively movable with the outer curved surface of the wrapping plate 26. Abutment; an electric telescopic rod 270 is fixedly mounted on the lower surface of the upper ring plate 28, and the output end of the electric telescopic rod 270 is fixedly connected to the end of the parallel link 27 away from the lower ring plate 271. A guide column 281 is fixedly mounted on the side of the upper ring plate 28 away from the parallel link 27. An upper annular seat 29 is fixedly mounted on the upper outer surface of the guide column 281. A petal-shaped guard plate 291 is movably connected to the lower inner ring surface of the upper annular seat 29. The petal-shaped guard plates 291 are provided in multiple groups and are arranged in a circular array about the central axis of the upper annular seat 29;

[0042] In this embodiment, the electric telescopic rod 270 is electrically connected to the induction ring plate 124. After the induction ring plate 124 detects and analyzes the collected sample information in real time, such as the drilling speed and hardness of the rock formation, a data transmission module is integrated inside the drill bit body 1 to transmit the collected rock formation information to the ground equipment in real time for real-time analysis and processing. At the same time, an artificial intelligence algorithm is used to deeply mine the data to provide support for drilling decisions. At this time, the parallel link 27 is controlled by the electrical connection between the induction ring plate 124 and the electric telescopic rod 270. When the parallel link 27 is raised and lowered, it can drive the lower ring plate 271 and the claw-shaped contact block 272 to move synchronously, forming a claw-shaped design. The claw-shaped contact block 272 clamps and relaxes the upper part of the multiple groups of wrapping plates 26, which facilitates the adjustment of the size of the opening formed by the multiple groups of wrapping plates 26 and avoids the situation where the rock formation collection speed is too fast or blockage occurs. It is worth noting that sensors are provided inside the lower ring plate 271 and the upper ring plate 28 to facilitate real-time analysis of the volume of collected rock formation information.

[0043] Example 5, refer to the attached Figure 1-14On the basis of the fourth embodiment, in order to achieve the stability of drilling during rock formation information collection and to avoid the situation where the formation collapses and is difficult to extract after the sampling is completed: the lower outer surface of the docking sleeve 31 is threadedly connected to the inner surface of the threaded joint 24, and the upper surface of the docking sleeve 31 is fixedly connected to the outer surface of the lower column 321. The lower column 321 and the upper column 322 are an integrally formed structure. The outer ring surface of the upper column 322 is evenly provided with reserved grooves 3220, and the outer circumferential surface of the lower column 321 is fixedly installed with convex 3211; The inner wall of the convex column 3211 is respectively provided with a buffer cavity 1 32110 and a buffer cavity 2 321102, a communicating hole 321101 is provided between the buffer cavity 1 32110 and the buffer cavity 2 321102, the interior of the buffer cavity 1 32110 is movably connected with the supporting column 1 3212, the inner surface of the buffer cavity 2 321102 is movably connected with the supporting column 2 323, the upper end of the supporting column 2 323 is fixedly installed with a receiving plate 324, the supporting column 2 323 and the supporting column 1 32 The cross-sections of the first and second retaining columns 321 and 322 are all set to a "T"-shaped structure. A spring 3231 is sleeved on the outer surface of the lower side of the second retaining column 323. One end of the spring 3231 is fixedly connected to the top surface of the inner cavity of the second buffer cavity 321102. The inner side of the lower end of the reserved groove 3220 is movably connected to the movable blade 3221. The outer surface of the lower side of the movable blade 3221 is movably abutted against the outer surface of the top end of the first retaining column 3212. The inner side of the end of the movable blade 3221 away from the protruding column 3211 is fixedly connected to the elastic strip 3222. The other end of the elastic support bar 3222 is fixedly connected to the fixing bar 3223, and the end of the fixing bar 3223 away from the elastic support bar 3222 is fixedly connected to the upper inner wall of the reserved groove 3220. A limiting hole is provided on the inner wall of the fixing bar 3223, and the inner surface of the limiting hole is slidably connected to the outer surface of the second supporting column 323; the movable blade body 3221 is fixedly provided with a rock cutting tip 32211 at one end close to the elastic support bar 3222; the movable blade body 3221 and the rock cutting tip 32211 are formed as one piece;

[0044] In this embodiment, the rod stabilizing mechanism 3 is connected to the end of the rod body 2 away from the drill bit body 1, and the threaded joint 24 is used to realize the installation of the rod body 2 and the rod stabilizing mechanism 3 as a whole. After the sampling of the rock formation information is completed, the drill bit body 1 and the rod body 2 are lifted upward as a whole. If the formation surface collapses, the upper part of the receiving plate 324 will first contact the formation surface. At this time, when the pressure of the upper rock formation is too large, the receiving plate 324 is pressed downward. At this time, the gas in the inner cavity of the buffer chamber 2 321102 is discharged into the inner cavity bottom side of the buffer chamber 1 32110 through the connecting hole 321101. At this time, the gas pushes the supporting column 1 3212 to move upward. Figure 9-10As shown, the top of the supporting column 3212 contacts the lower side of the movable blade 3221. At this time, the multiple groups of movable blades 3221 contact the lower side of the upper end of the receiving plate 324, preventing the receiving plate 324 from falling due to the pressure of the upper rock formation, thereby preventing the movable blade 3221 and the rock cutting tip 32211 from being compressed, thereby protecting the rock cutting tip 32211.

[0045] It should be noted that when the surface of the formation has not collapsed, the top of the supporting column 323 and the receiving plate 324 are not compressed by the formation, and the drill bit body 1 gradually drills into the formation. At this time, the outward-extended movable cutter body 3221 and the rock-cutting tip 32211 resist the side wall of the drilled formation, thereby improving the stability during drilling and reducing the vibration transmission to the arms during drilling sampling, thereby reducing the vibration sensation of the arms. In addition, the rock-cutting tip 32211 can also cut the upper rock formation, thereby avoiding the collapse of rock chips to form a rock chip bed, making it difficult to remove the collected rock formation, and resulting in difficulty in recovering the drill bit body 1.

[0046] The working principle and use process of the present invention are as follows: in actual use, first, the combined rod body 1 21 and the combined rod body 2 22 are connected and assembled to form a complete cylindrical rod body, forming a seamless splicing of the combined rod body 1 21 and the combined rod body 2 22, and the combination of the threaded joint 1 23 and the threaded joint 2 24 are used to realize the fastening installation of the two ends of the combined rod body 1 21 and the combined rod body 2 22. After the assembly of the combined rod body 1 21 and the combined rod body 2 22 is completed, a tubular cavity is formed inside, and the end of the rod body 2 away from the drill bit body 1 is connected to the stabilizing rod mechanism 3, and the threaded joint 2 24 is used to realize the overall installation of the rod body 2 and the stabilizing rod mechanism 3; then, when drilling into the bottom surface of the ore layer, the drill bit body 1 is used to drill into the end and inlay multiple pieces of metal. The diamond composite piece enhances the excavation ability in a high temperature environment. A spiral convex pattern 1211 is added to the inner ring surface of the lower conical kit 121 to facilitate rapid sampling and transportation of the rock formation of the sampling port 10. Through the setting of the conical steel plate 123, its surface is made of smooth stainless steel, which contacts the surface of the rock formation, reducing the resistance between the rock formation and the rock formation. By using the setting of the induction ring plate 124, the temperature, chemical composition and other information of the rock formation are obtained in time, providing more comprehensive rock formation data. In addition, the lower anti-falling part is integrated on the inner side of the upper threaded kit 122. When the collected rock formation sample is transported upward through the sampling port 10, the rock formation breaks upward. At this time, the multiple groups of wrapping plates 26 are impacted by the rock formation below and swing, forming a wrapping. The multiple groups of wrapping plates 26 of the shaped structure are deformed to form a petal-shaped structure. After the rock formation breaks through the wrapping plates 26, it enters the storage tube cavity formed by the combined rod body 1 21 and the combined rod body 2 22. Subsequently, the multiple groups of wrapping plates 26 are gradually retracted toward the center under the elastic force of the torsion spring 2622 to prevent the central rock formation sample from collapsing and falling. In addition, when the rock formation information sampling is completed, the drill bit body 1 and the rod body 2 are lifted upward as a whole. If the formation surface collapses, the upper part of the receiving plate 324 will first contact the formation surface. When the upper rock formation pressure is too large, the receiving plate 324 will be pressed downward. At this time, the gas in the inner cavity of the buffer chamber 2 321102 is discharged into the buffer chamber 1 3 through the connecting hole 321101. On the bottom side of the inner cavity of 2110, the gas propels the supporting column 1 3212 to move upward, and the top of the supporting column 1 3212 resists the lower side of the movable blade body 3221. At this time, multiple groups of movable blade bodies 3221 resist the lower side of the upper end of the receiving plate 324, preventing the receiving plate 324 from falling due to the pressure of the upper rock formation, thereby causing the movable blade body 3221 and the rock cutting tip 32211 to be compressed, thereby playing a protective role for the rock cutting tip 32211; finally, after the drill bit is pulled out as a whole, the threaded joint 1 23 and the threaded joint 2 24 are screwed to disassemble the drill bit as a whole, and the combined rod body 1 21 and the combined rod body 2 22 are separated, and the rock formation samples collected preliminarily are taken out and marked for storage.
