Description
Technical Field
[0001] The present invention relates to the technical field of drilling in soil layers or rocks, and more specifically, it relates to a deep rock mass structure feature and trajectory while-drilling testing equipment. Background Art
[0002] Rock mass mechanical parameters and rock mass geological mechanics characteristics such as structure are the basic basis for underground engineering surrounding rock classification, stability analysis and support design. Rapid and effective prediction of rock mass geological mechanics characteristics is the premise to ensure the safe and efficient construction of underground engineering. Therefore, in-situ identification of rock types, structural characteristics and rock mass quality evaluation is crucial. However, due to the existence of a large number of fissures inside the rock mass, there are fissure structural planes with different angles, lengths and widths inside it, and these fissure structural planes seriously weaken the strength and stability of the rock mass. Therefore, it is particularly important to obtain the distribution of rock mass structural planes in advance for the design of underground engineering support schemes.
[0003] A while-drilling measurement device is a device that monitors and quantitatively controls while-drilling parameters such as drilling speed, rotation speed, and drilling pressure during the drilling process. By analyzing and applying the monitoring data in this way, it is convenient to better understand and predict the behavior of the rock mass, so as to achieve the theoretical relationship between rock mass fissure parameters and while-drilling parameters. However, the while-drilling measurement device will encounter different geological conditions during use. When drilling in unstable strata, the prior art generally uses a single-eccentric root tube drill tool; for example, the Chinese invention patent application with the publication number CN119308602A discloses a rotary steering offset mechanism for while-drilling measurement and control. In its technical solution, an eccentric guide is set to drive the drill bit to deflect. Although the technical solution of this patent can control the drilling direction of the drill bit through the eccentric principle during the while-drilling measurement process, its stability is poor under the condition of large impact force.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the detailed implementation manners of the present invention will be described in detail below with reference to the accompanying drawings of the specification.
[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.
[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.
[0026] Embodiment 1 Embodiment 1 further describes the deep rock mass structure characteristics and the trajectory while-drilling testing equipment proposed by the present invention, including the main body 100 of the testing device. A hydraulic drilling unit 101 is arranged on the main body 100 of the testing device. A drill pipe main body 102 is arranged in the hydraulic drilling unit 101. A probe groove 103 is arranged in the drill pipe main body 102. A probe pipe 104 is arranged in the probe groove 103. When installing the probe pipe 104, only need to install the probe pipe 104 in the probe groove 103 and lock it through a screw sleeve to realize the locking of the probe pipe 104. The probe pipe 104 includes a sonic detection device 106, a memory 107, an angle sensor 108 and a depth sensor 109. One end of the drill pipe main body 102 is provided with a reaming bit 111. A center bit 112 is integrally formed on the reaming bit 111. The reaming bit 111 and the center bit 112 are coaxially arranged. A plurality of groups of chip removal grooves 113 are uniformly arranged on the outer wall of the center bit 112 along the circumferential direction. A plurality of groups of chip removal grooves 114 are uniformly arranged on the reaming bit 111 along the circumferential direction. The diameter of the chip removal groove 114 is larger than that of the chip removal groove 113. The chip removal grooves 114 and 113 are opened to the same depth. The chip removal groove 114 communicates with the chip removal groove 113 correspondingly. A reaming mechanism 200 is arranged in the reaming bit 111; Due to the existence of a large number of fissures inside the rock mass, there are fissure structural planes with different angles, lengths, and widths inside it. These fissure structural planes seriously weaken the strength and stability of the rock mass. Therefore, obtaining the distribution of the rock mass structural planes in advance is particularly important for the design of underground engineering support schemes. Digital drilling technology provides a new idea for rock mass fissure detection. Its core is to establish the theoretical relationship between rock mass fissure parameters and drilling parameters while drilling. The present invention monitors the rock mass structural characteristics, spatial trajectory, and drilling depth while drilling parameters through a testing device during the drilling process. Thus, analysis and application can be carried out based on these data to better understand and predict the behavior of the rock mass; Among them, the acoustic wave detection device 106 is used to monitor the acoustic wave characteristics during drilling and analyze the rock mass structural characteristics. The angle sensor 108 and the depth sensor 109 are used to determine the drilling hole spatial trajectory and automatically and accurately measure the drilling hole depth. The storage 107 is used for the measurement data generated by the acoustic wave detection device 106, the angle sensor 108, and the depth sensor 109. In order to ensure the comprehensiveness of the measurement data, ACPR, INP, LDI, MAST, IFPT while-drilling instruments can be hung inside the drill pipe body 102 to provide while-drilling parameters such as natural gamma, electromagnetic wave resistivity, neutron porosity, lithology density, and formation pressure, so as to achieve the theoretical relationship between rock mass fissure parameters and while-drilling parameters; Moreover, the while-drilling instruments will encounter different geological conditions during use. When drilling in unstable formations, the prior art generally uses a single-eccentric root drill tool, but in the case of a large impact force, the stability is poor. The present invention further improves the prior art. A hole expanding mechanism 200 is provided inside the drill pipe body 102. The screw 201e moves inside the drill pipe body 102 to drive the hole expanding member 203 to extend outwards or retract. It not only has better stability but also can meet the requirements of unstable formations and improve the rock breaking efficiency; The hole expanding mechanism 200 includes a connecting member 201 provided inside the hole expanding bit 111. A movable member 202 is provided at the bottom end of the connecting member 201. The hole expanding member 203 is provided inside the hole expanding bit 111. The connecting member 201 and the movable member 202 cooperate to adjust the hole expanding member 203. The present invention further improves the hole expanding bit 111. The connecting member 201 and the movable member 202 are provided inside the hole expanding bit 111. The screw 201e inside the connecting member 201 drives the movable member 202 to move, so that the movable member 202 squeezes the hole expanding member 203, and thus the hole expanding member 203 extends outwards or retracts inside the hole expanding bit 111; It further includes an adjustment assembly 300 disposed within the diameter-expanding mechanism 200. The adjustment assembly 300 includes a rotating member 301 provided on the reaming bit 111. The connecting member 201 is engaged with the rotating member 301. An adjusting member 302 is provided within the rotating member 301. The rotating member 301 and the adjusting member 302 cooperate to divide the second chip removal groove 114. It also includes a chip removal member 303 provided on the drill pipe body 102. The chip removal member 303 and the adjusting member 302 cooperate to optimize the chip removal of the drill pipe body 102; To improve the rock-breaking efficiency of the drill pipe body 102, the present device further refines the powder discharge structure of the reaming bit 111. By providing a rotating member 301 within the reaming bit 111, when the connecting member 201 operates, it drives the rotating member 301 to move synchronously. At this time, the connecting member 201 and the rotating member 301 cooperate, causing the angle of the adjusting member 302 within the rotating member 301 to deflect, thereby dividing the second chip removal groove 114. In this way, the crushed rock located within the second chip removal groove 114 is broken, having better powder discharge efficiency and drilling strength; Working principle: When the present device is in use, the acoustic characteristics during the drilling process can be monitored through the acoustic detection device 106 to analyze the rock mass structure characteristics. The angle sensor 108 and the depth sensor 109 are used to measure the drilling hole space trajectory and automatically and accurately measure the drilling depth. The memory 107 is used for the measurement data generated by the acoustic detection device 106, the angle sensor 108, and the depth sensor 109. Thus, these data can be analyzed and applied to better understand and predict the behavior of the rock mass; Moreover, the drill pipe body 102 of the present device can be divided into two stages. During normal use, the diameter-expanding member 203 within the reaming bit 111 retracts. At this time, the reaming bit 111 and the center bit 112 form a complete bit for operation. When encountering an unstable formation, the movable member 202 is driven to move through the internal screw 201e of the connecting member 201, causing the movable member 202 to squeeze the diameter-expanding member 203. As a result, the diameter-expanding member 203 extends outward within the reaming bit 111 to adapt to different formations. And since the internal structure of the present device is a triangular structure and the diameter-expanding member 203 is tightened by the screw 201e, the present device has better stability during use; At the same time, the present invention provides an adjustment assembly 300. Through the cooperation of the connecting member 201 and the rotating member 301, the angle of the adjusting member 302 within the rotating member 301 deflects, thereby dividing the second chip removal groove 114. In this way, the crushed rock located within the second chip removal groove 114 is broken, having better powder discharge efficiency and drilling strength, and improving the rock-breaking efficiency of the drill pipe body 102.
[0027] Embodiment 2 Based on the first embodiment, the following technical features are added: The connecting member 201 includes a first connecting portion 201a fixedly connected to the drill pipe body 102. A second connecting portion 201b is fixedly connected to the reaming bit 111. The first connecting portion 201a and the second connecting portion 201b are in threaded cooperation. A central channel 201c axially penetrating and extending into the reaming bit 111 is provided in the middle of the second connecting portion 201b. A support plate 201d is fixedly connected in the central channel 201c. A screw rod 201e is provided at the central position of the support plate 201d. The screw rod 201e penetrates the support plate 201d and is rotatably connected to a pressure rod 201f at the position in the central channel 201c. A limiting block 201g is fixedly connected to one side of the pressure rod 201f. One end of the limiting block 201g is slidably connected to the inner wall of the central channel 201c. A limiting groove for cooperating with the limiting block 201g is provided in the central channel 201c, and the limiting groove is vertically downward. Therefore, the limiting block 201g can only perform vertical displacement; It can be Figures 1 to 8 seen that the drill pipe body 102 and the reaming bit 111 are assembled by threads, and a cylindrical central channel 201c is formed inside. A circular support plate 201d is fixedly connected in the central channel 201c. A screw rod 201e is threadedly connected inside the support plate 201d. The upper end of the pressure rod 201f is rotatably connected inside the screw rod 201e. A limiting block 201g is fixedly connected to the side wall of the pressure rod 201f. The corresponding limiting block 201g is slidably connected inside the central channel 201c. Thus, when the screw rod 201e rotates and moves downward, since the displacement of the limiting block 201g in the vertical direction is restricted, the pressure rod 201f cannot rotate. At this time, the pressure rod 201f moves vertically downward; The movable member 202 includes a movable block 202a provided at the bottom end of the pressure rod 201f. The movable block 202a is slidably connected in the central channel 201c. A plurality of first shaft seats 202b are fixedly connected to the bottom end of the movable block 202a in a circumferential manner. A connecting rod 202c is rotatably connected inside the plurality of first shaft seats 202b. One end of the connecting rod 202c is rotatably connected to a second shaft seat 202d, and the second shaft seat 202d is correspondingly provided on the expanding member 203; It can be Figures 4 to 11 seen that a circular movable block 202a is fixed to the bottom end of the pressure rod 201f. The movable block 202a performs vertical displacement inside the central channel 201c. A plurality of first shaft seats 202b are fixedly connected to the bottom end of the movable block 202a in a circumferential manner. The first shaft seats 202b are rotatably connected to the second shaft seat 202d through the connecting rod 202c. The second shaft seat 202d is correspondingly fixedly connected to the expanding member 203. When the movable block 202a moves downward, due to the extrusion force, the connecting rod 202c rotates on the first shaft seat 202b and the second shaft seat 202d, thereby driving the expanding member 203 to extend outwards; The diameter-expanding member 203 includes multiple groups of openings 203a circumferentially formed on the reaming bit 111. The openings 203a correspondingly communicate with the central channel 201c. Diameter-expanding blocks 203b are slidably connected in the corresponding openings 203a. Grooves 203c are provided on the opposite sides of the multiple groups of diameter-expanding blocks 203b. The second shaft seat 202d is fixedly connected in the grooves 203c correspondingly. Diameter-expanding teeth 203d are integrally formed on the diameter-expanding blocks 203b, and crushing teeth 203e are integrally formed on the diameter-expanding teeth 203d. The diameter-expanding teeth 203d and the crushing teeth 203e are correspondingly arranged in the second chip removal groove 114; As Figures 6 to 11 can be seen, three groups of openings 203a are circumferentially provided on the outer wall of the reaming bit, and diameter-expanding blocks 203b are slidably connected in the openings 203a. The openings 203a limit the movement direction of the diameter-expanding blocks 203b. In this way, the diameter-expanding blocks 203b can only move within the range restricted by the openings 203a. Since the second shaft seat 202d is fixedly connected to the side wall of the diameter-expanding block 203b, when the connecting rod 202c rotates on the first shaft seat 202b and the second shaft seat 202d, the diameter-expanding block 203b is thus squeezed, causing the diameter-expanding block 203b to extend outwards. Moreover, diameter-expanding teeth 203d are integrally formed on the diameter-expanding blocks 203b, further improving the rock-breaking efficiency; Working principle: When encountering an unstable formation, the operator can rotate the screw rod 201e through a wrench. The screw rod 201e makes a rotational downward movement in the support plate 201d. When the screw rod 201e makes a rotational downward movement, since the displacement of the limiting block 201g in the vertical direction is restricted, the pressure rod 201f on the limiting block 201g thus moves vertically downwards. At this time, the pressure rod 201f drives the movable block 202a to move downwards. Due to the extrusion force, the connecting rod 202c rotates on the first shaft seat 202b and the second shaft seat 202d, thereby driving the diameter-expanding block 203b on the second shaft seat 202d to slide in the opening 203a. In this way, the diameter-expanding block 203b on the reaming bit 111 extends out, further improving the rock-breaking efficiency. Moreover, the connecting rod 202c is arranged in a triangular symmetry, so that the diameter-expanding block 203b has better stability during operation.
[0028] Embodiment 3 Based on Embodiment 2, the following technical features are added: The rotating member 301 includes an annular plate 301a rotatably connected in the central channel 201c. A central hole 301b is provided in the middle position of the annular plate 301a. The diameter of the central hole 301b is larger than the diameter of the pressure rod 201f. A limiting strip 301c is integrally formed on the outer wall of the pressure rod 201f. A deflection groove 301d is provided on the inner wall of the central hole 301b. The deflection groove 301d is inclined. The limiting strip 301c is slidably connected in the deflection groove 301d correspondingly. Therefore, when the limiting strip 301c on the pressure rod 201f moves downwards, the annular plate 301a is driven to rotate. The height of the deflection groove 301d in the vertical direction is smaller than that of the central hole 301b; As can be seen from Figures 6 to 11 this, a circular annular plate 301a is rotatably connected inside the central channel 201c. A circular central hole 301b is provided at the middle position of the annular plate 301a. The pressure rod 201f correspondingly passes through the central hole 301b. The present invention further defines the connection relationship between the pressure rod 201f and the annular plate 301a. The limiting strip 301c on the outer wall of the pressure rod 201f is correspondingly slidably connected in the deflection groove 301d. Since the deflection groove 301d is provided in the central hole 301b and the height of the deflection groove 301d in the vertical direction is less than that of the central hole 301b, the distance of the pressure rod 201f moving in the vertical direction can be controlled in this way. It can be known from this that the distance that the screw rod 201e can rotate and move downward is the height of the deflection groove 301d in the vertical direction; The adjusting member 302 includes a plurality of groups of arc-shaped grooves 302a uniformly formed in a circumferential manner on the annular plate 301a. An adjusting rod 302b is slidably connected in each of the arc-shaped grooves 302a. The arc-shaped groove 302a is composed of an initial section 302c, a transition section 302d, and a termination section 302e. The adjusting rod 302b is slidably connected in the initial section 302c, the transition section 302d, and the termination section 302e. A support block 302f is fixedly connected to the upper end surface of the adjusting rod 302b. A sleeve 302h is fixedly connected to the side wall of the support block 302f. An activity groove 302i is formed by inward depression of the sleeve 302h. A positioning block 302j is integrally formed on the inner wall of the activity groove 302i. An activity rod 302k is movably connected in the activity groove 302i. A surrounding groove 302l is provided on the activity rod 302k. The positioning block 302j is correspondingly slidably connected in the surrounding groove 302l. One end of the activity rod 302k passing through the reaming drill bit 111 is fixedly connected with a cutting part 302m. The diameter of the cutting part 302m gradually decreases from the middle to both ends. The cutting part 302m is correspondingly located in the chip removal groove two 114; As can be seen from Figures 7 to 12 this, the activity rod 302k is rotatably connected inside the reaming drill bit 111, and the positioning block 302j on the activity rod 302k is slidably connected in the surrounding groove 302l of the sleeve 302h. In this way, the direction inside the sleeve 302h is fixed, so that the sleeve 302h slides on the activity rod 302k. And the bottom end of the sleeve 302h is fixedly connected with a support block 302f. A support block 302f is fixedly connected with an adjusting rod 302b. The adjusting rod 302b is correspondingly slidably connected in the arc-shaped groove 302a. The arc-shaped groove 302a is composed of an initial section 302c, a transition section 302d, and a termination section 302e. When the annular plate 301a rotates, the arc-shaped groove 302a squeezes the adjusting rod 302b, so that the sleeve 302h slides on the activity rod 302k. And when the adjusting rod 302b is located at different positions of the initial section 302c, the transition section 302d, and the termination section 302e, the moving distance of the sleeve 302h is limited; Working principle: By setting the adjusting component 300, the powder discharge structure of the reaming bit 111 during rock breaking is further refined. When the pressure rod 201f moves downward, the limiting strip 301c on the outer wall of the pressure rod 201f is slidably connected to the deflection groove 301d correspondingly, thereby driving the annular plate 301a to rotate. When the annular plate 301a rotates, the arc groove 302a in the annular plate 301a squeezes the adjusting rod 302b. At this time, the support block 302f and the sleeve 302h on the pressure rod 201f move on the movable rod 302k, and the positioning block 302j on the movable rod 302k is slidably connected to the surrounding groove 302l of the sleeve 302h. At this time, the cutting part 302m on the movable rod 302k rotates in the chip discharge groove II 114, so as to crush the broken rock mass and further improve the powder discharge efficiency.

A plurality of cutting grooves 303b are provided around the outer wall of the drill pipe body 102. The spiral powder discharge groove 303a intersects with the cutting grooves 303b. The spiral powder discharge groove 303a divides the cutting surface into a plurality of crushing areas 303c. The depth of the chip discharge groove II 114 is greater than the depth of the cutting grooves 303b. The spiral powder discharge groove 303a is wound around the drill pipe body 102. A plurality of crushing teeth 303d are fixedly connected in the crushing areas 303c. The crushing teeth 303d are arranged in a stepped manner. The crushing teeth 303d crush the crushed stones passing through the spiral powder discharge groove 303a; From Figures 2 to 7 It can be seen that the present invention ensures more powerful powder discharge efficiency and drilling strength through the cooperation of the spiral powder discharge groove 303a and the cutting grooves 303b. And because the spiral powder discharge groove 303a divides the cutting grooves 303b into a plurality of crushing areas 303c, when discharging powder, the crushed slag is discharged along with the spiral powder discharge groove 303a. And three groups of crushing teeth 303d are fixedly connected to the corresponding position on the drill pipe body 102. The crushing teeth 303d are arranged in a stepped manner. In this way, the transported crushed rock is crushed to ensure the efficiency during transportation; Working principle: In summary, the present invention divides the cutting grooves 303b into a plurality of crushing areas 303c through the spiral powder discharge groove 303a, and three groups of crushing teeth 303d are arranged in the crushing areas 303c. The crushing teeth 303d are arranged in a stepped manner. When the drill pipe body 102 breaks the hole, the larger crushed rock is broken by the stepped crushing teeth 303d, so that the spiral powder discharge groove 303a discharges powder more smoothly and improves the working efficiency of the drill pipe.
