Description

Technical Field

[0001] The present invention relates to the technical field of soil or rock drilling, and more particularly to a deep rock mass structural feature and trajectory while-drilling testing equipment. Background Art

[0002] Rock mass geomechanical characteristics, such as rock mass mechanical parameters and structure, are the basic basis for surrounding rock classification, stability analysis, and support design for underground engineering. Rapid and effective prediction of rock mass geomechanical characteristics is a prerequisite for ensuring safe and efficient construction of underground engineering. Therefore, in-situ identification of rock types, structural properties, and rock mass quality evaluation are crucial. However, due to the large number of cracks within the rock mass, there are crack structural surfaces with different angles, lengths, and widths. These crack structural surfaces seriously weaken the strength and stability of the rock mass. Therefore, obtaining the distribution of rock mass structural surfaces in advance is particularly important for the design of underground engineering support schemes.

[0003] A measurement while drilling device is a device that monitors and quantitatively controls drilling parameters such as drilling speed, rotation speed, and drilling pressure during the drilling process. The monitoring data is analyzed and applied in this way to better understand and predict the behavior of the rock mass, thereby achieving a theoretical relationship between rock mass fracture parameters and drilling parameters. However, the measurement while drilling device may encounter different geological conditions during use. When drilling into unstable formations, the existing technology generally uses a single eccentric root canal drill tool; for example, Chinese invention patent application publication number CN119308602A discloses a rotary steering bias mechanism for drilling while drilling measurement and control. Its technical solution drives the drill bit to deflect by providing an eccentric guide. Although the technical solution of this patent can control the drilling direction of the drill bit through the eccentricity principle during the drilling while drilling measurement process, its stability is poor under conditions of large impact force.

DETAILED DESCRIPTION

[0034] To facilitate understanding of the present invention, the present invention is further described below with reference to the accompanying drawings.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1

[0039] The first embodiment of the present invention further describes the deep rock structure characteristics and trajectory drilling test equipment, including a test device body 100, a hydraulic drilling unit 101 is provided on the test device body 100, a drill rod body 102 is provided in the hydraulic drilling unit 101, a probe groove 103 is provided in the drill rod body 102, a probe tube 104 is provided in the probe groove 103, and when installing the probe tube 104, it is only necessary to install the probe tube 104 in the probe groove 103 and lock it by a screw sleeve to achieve the locking of the probe tube 104. The probe tube 104 includes an acoustic wave detection device 106, a storage 107, an angle sensor 108 and a depth sensor. Sensor 109, a reaming drill bit 111 is provided at one end of the drill rod body 102, and a center drill bit 112 is integrally formed on the reaming drill bit 111. The reaming drill bit 111 and the center drill bit 112 are coaxially arranged. The outer wall of the center drill bit 112 is evenly provided with multiple groups of chip grooves 113 along the circumferential direction. The reaming drill bit 111 is evenly provided with multiple groups of chip grooves 2 114 along the circumferential direction. The chip grooves 2 114 are larger than the diameter of the chip grooves 1 13. The chip grooves 2 114 and the chip grooves 1 113 have the same depth. The chip grooves 2 114 are correspondingly connected to the chip grooves 1 113. A diameter expansion mechanism 200 is provided in the reaming drill bit 111;

[0040] Since there are a large number of cracks inside the rock mass, there are crack structural surfaces with different angles, lengths and widths inside. These crack structural surfaces seriously weaken the strength and stability of the rock mass. Therefore, it is particularly important to obtain the distribution of rock structural surfaces in advance for the design of underground engineering support schemes. Digital drilling technology provides a new idea for rock crack detection. Its core is to establish a theoretical relationship between rock crack parameters and drilling parameters. The present invention uses a testing device to monitor the rock structure characteristics, spatial trajectory and drilling depth parameters during the drilling process. In this way, the data can be analyzed and applied to better understand and predict the behavior of the rock mass.

[0041] The acoustic wave detection device 106 is used to monitor the acoustic wave characteristics during the drilling process and analyze the rock structure characteristics. The angle sensor 108 and the depth sensor 109 are used to determine the spatial trajectory of the borehole and automatically and accurately measure the borehole depth. The storage 107 is used to store 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, and IFPT downhole instruments can be hung in the drill pipe body 102 to provide downhole parameters such as natural gamma, electromagnetic wave resistivity, neutron porosity, lithology density, and formation pressure, so as to achieve the theoretical relationship between rock fracture parameters and downhole parameters.

[0042] Moreover, the drilling instrument may encounter different geological conditions during use. When drilling into unstable formations, the existing technology generally uses a single eccentric root canal drill, but under the condition of large impact force, the stability is poor. The present invention further improves the existing technology and provides an expansion mechanism 200 in the drill rod body 102. The screw 201e moves inside the drill rod body 102, driving the expansion member 203 to extend or retract outward. This not only has better stability, but also can meet the needs of unstable formations and improve rock breaking efficiency.

[0043] The diameter expansion mechanism 200 includes a connecting member 201 disposed within the reaming drill bit 111. A movable member 202 is provided at the bottom end of the connecting member 201. A diameter expansion member 203 is provided within the reaming drill bit 111. The connecting member 201 and the movable member 202 cooperate to adjust the diameter expansion member 203. The present invention further improves the reaming drill bit 111. The connecting member 201 and the movable member 202 are provided within the reaming drill bit 111. The movable member 202 is driven to move by a screw 201e within the connecting member 201, causing the movable member 202 to squeeze the diameter expansion member 203, thereby extending or retracting the diameter expansion member 203 within the reaming drill bit 111.

[0044] The drill bit 111 further includes an adjusting assembly 300 disposed within the diameter expansion mechanism 200. The adjusting assembly 300 includes a rotating member 301 disposed on the reaming drill bit 111. The connecting member 201 cooperates with the rotating member 301. An adjusting member 302 is disposed within the rotating member 301. The rotating member 301 and the adjusting member 302 cooperate to divide the second chip removal groove 114. The drill bit 111 further includes a chip removal member 303 disposed on the drill rod body 102. The chip removal member 303 and the adjusting member 302 cooperate to optimize chip removal from the drill rod body 102.

[0045] In order to improve the rock breaking efficiency of the drill pipe body 102, the present device further refines the dust removal structure of the reaming drill bit 111. By providing a rotating member 301 in the reaming drill bit 111, when the connecting member 201 operates, the rotating member 301 is driven to move synchronously. At this time, the connecting member 201 and the rotating member 301 cooperate to cause the angle of the adjusting member 302 in the rotating member 301 to deflect, thereby dividing the second chip groove 114. In this way, the crushed rock in the second chip groove 114 is crushed, achieving better dust removal efficiency and drilling strength.

[0046] Working Principle: When in use, the device can monitor the acoustic wave characteristics during the drilling process through the acoustic wave detection device 106 and analyze the structural characteristics of the rock mass. The angle sensor 108 and the depth sensor 109 are used to determine the spatial trajectory of the drilling hole and automatically and accurately measure the drilling depth. The storage 107 is used to store the measurement data generated by the acoustic wave detection device 106, the angle sensor 108 and the depth sensor 109. In this way, the data can be analyzed and applied to better understand and predict the behavior of the rock mass.

[0047] The drill rod body 102 of the present device can be divided into two stages. During normal use, the diameter-expanding member 203 in the reaming drill bit 111 is retracted. At this time, the reaming drill bit 111 and the center drill bit 112 form a complete drill bit for operation. When encountering unstable formations, the movable member 202 is driven to move by the screw 201e inside the connecting member 201, so that the movable member 202 squeezes the diameter-expanding member 203, so that the diameter-expanding member 203 extends outward from the reaming drill bit 111, thereby adapting to different formations. In addition, since the internal structure of the present device is triangular and the diameter-expanding member 203 is tightened by the screw 201e, the present device has better stability during use.

[0048] At the same time, the present invention is provided with an adjustment assembly 300, which cooperates with the connecting member 201 and the rotating member 301 to deflect the angle of the adjustment member 302 in the rotating member 301, thereby dividing the second chip groove 114, thereby crushing the crushed rock in the second chip groove 114, having better powder removal efficiency and drilling strength, and improving the rock breaking efficiency of the drill rod body 102.

[0049] Example 2

[0050] The following technical features are added on the basis of the first embodiment: the connecting member 201 includes a connecting portion 1 201a fixedly connected to the drill rod body 102, a connecting portion 201b fixedly connected to the reaming drill bit 111, the connecting portion 1 201a and the connecting portion 201b are threaded together, the middle portion of the connecting portion 201b is provided with a central channel 201c that axially penetrates and extends into the reaming drill bit 111, and a support plate 201d is fixedly connected to the central channel 201c. A screw rod 201e is provided at the center of the plate 201d. The screw rod 201e passes through the support plate 201d and is rotatably connected to a pressure rod 201f at a position located in the center channel 201c. One side of the pressure rod 201f is fixedly connected to a limit block 201g. One end of the limit block 201g is slidably connected to the inner wall of the center channel 201c. A limit groove is provided in the center channel 201c to match the limit block 201g, and the limit groove is vertically downward, so the limit block 201g can only move in the vertical direction.

[0051] Depend on Figures 1 to 8It can be seen that the drill rod body 102 and the reaming drill bit 111 are assembled by threads, and a cylindrical central channel 201c is formed therein. A circular support plate 201d is fixedly connected in the central channel 201c, and a screw 201e is threadedly connected in the support plate 201d. The upper end of the pressure rod 201f is rotatably connected in the screw 201e, and the side wall of the pressure rod 201f is fixedly connected to the limit block 201g, and the limit block 201g is correspondingly slidably connected in the central channel 201c. In this way, when the screw 201e rotates and moves downward, the displacement of the limit block 201g in the vertical direction is restricted, so that the pressure rod 201f cannot rotate, and the pressure rod 201f moves vertically downward.

[0052] 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 to the central channel 201c. The bottom end of the movable block 202a is circumferentially fixedly connected to multiple sets of shaft seats 1 202b. The multiple sets of shaft seats 1 202b are rotatably connected to connecting rods 202c. One end of the connecting rod 202c is rotatably connected to shaft seat 202d. Shaft seat 202d is correspondingly provided on the diameter expansion member 203.

[0053] Depend on Figures 4 to 11 It can be seen that a circular movable block 202a is fixed to the bottom end of the pressure rod 201f. The movable block 202a is displaced in the vertical direction within the central channel 201c. The bottom end of the movable block 202a is circumferentially fixedly connected to three sets of shaft seats 1 202b. The shaft seats 1 202b are rotatably connected to the shaft seats 2 202d via connecting rods 202c. The shaft seats 202d are correspondingly fixedly connected to the diameter expansion member 203. When the movable block 202a moves downward, the squeezing force causes the connecting rod 202c to rotate on the shaft seats 1 202b and the shaft seats 2 202d, thereby driving the diameter expansion member 203 to extend outward.

[0054] The expanding member 203 includes a plurality of groups of openings 203a circumferentially formed on the reaming drill bit 111. The openings 203a are correspondingly connected to the central channel 201c. Expanding blocks 203b are slidably connected to the corresponding openings 203a. Opposite sides of the plurality of expanding blocks 203b are provided with slots 203c. The second shaft seat 202d is correspondingly fixedly connected to the slots 203c. Expanding teeth 203d are integrally formed on the expanding blocks 203b. Crushing teeth 203e are integrally formed on the expanding teeth 203d. The expanding teeth 203d and the crushing teeth 203e are correspondingly disposed in the second chip removal groove 114.

[0055] Depend on Figures 6 to 11It can be seen that three groups of openings 203a are provided on the circumference of the outer wall of the expanding drill bit, and the expanding blocks 203b are slidably connected in the openings 203a. The openings 203a limit the movement direction of the expanding blocks 203b, so that the expanding blocks 203b can only move within the range limited by the openings 203a. Since the second shaft seat 202d is fixedly connected to the side wall of the expanding block 203b, when the connecting rod 202c rotates on the shaft seat 1 202b and the shaft seat 2 202d, the expanding block 203b is squeezed, causing the expanding block 203b to extend outward. In addition, the expanding block 203b is integrally formed with expanding teeth 203d, which further improves the rock breaking efficiency.

[0056] Working principle: When encountering unstable formations, the staff can use a wrench to rotate the screw 201e, and the screw 201e rotates and moves downward in the support plate 201d. When the screw 201e rotates and moves downward, the displacement of the limit block 201g in the vertical direction is restricted, so that the pressure rod 201f on the limit block 201g moves vertically downward. At this time, the pressure rod 201f drives the movable block 202a to move downward. Due to the extrusion force, the connecting rod 202c rotates on the shaft seat 1 202b and the shaft seat 2 202d, thereby driving the expanding block 203b on the shaft seat 202d to slide in the opening 203a, so that the expanding block 203b on the reaming drill bit 111 extends, further improving the rock breaking efficiency, and the connecting rod 202c is arranged in a triangular symmetry, so that the expanding block 203b has better stability during operation.

[0057] Example 3

[0058] On the basis of the second embodiment, the following technical features are added: the rotating member 301 includes an annular plate 301a rotatably connected to the central channel 201c, a central hole 301b is provided in the middle 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, and the limiting strip 301c is correspondingly slidably connected in the deflection groove 301d, so that when the limiting strip 301c on the pressure rod 201f moves downward, the annular plate 301a is driven to rotate, and the height of the deflection groove 301d in the vertical direction is smaller than the central hole 301b;

[0059] Depend on Figures 6 to 11It can be seen that a circular annular plate 301a is rotatably connected in the central channel 201c, and a circular central hole 301b is provided in 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 smaller than the central hole 301b, the distance that the pressure rod 201f moves in the vertical direction can be controlled. It can be seen that the distance that the screw rod 201e can rotate downward is the height of the deflection groove 301d in the vertical direction.

[0060] The adjusting member 302 includes a plurality of arcuate grooves 302a uniformly arranged on the annular plate 301a. The arcuate grooves 302a are all slidably connected to the adjusting rods 302b. The arcuate grooves 302a are composed of an initial section 302c, a transition section 302d and a terminal section 302e. The adjusting rods 302b are slidably connected to the initial section 302c, the transition section 302d and the terminal section 302e. The upper end surface of the adjusting rod 302b is fixedly connected to a support block 302f. The side wall of the support block 302f is fixedly connected to a sleeve 302h. The sleeve 302h is fixedly connected to the side wall of the sleeve 302h. 2h is inwardly recessed to form a movable groove 302i, and a positioning block 302j is integrally formed on the inner wall of the movable groove 302i. A movable rod 302k is movably connected in the movable groove 302i. The movable rod 302k is provided with a surrounding groove 302l. The positioning block 302j is correspondingly slidably connected in the surrounding groove 302l. One end of the movable rod 302k that passes through the reaming drill bit 111 is fixedly connected to a cutting portion 302m. The diameter of the cutting portion 302m gradually decreases from the middle to the two ends. The cutting portion 302m is correspondingly located in the second chip removal groove 114.

[0061] Depend on Figures 7 to 12 It can be seen that the movable rod 302k is rotatably connected to the reaming drill bit 111, and the positioning block 302j on the movable rod 302k is slidably connected to the surrounding groove 302l of the sleeve 302h, so that the direction in the sleeve 302h is fixed, so that the sleeve 302h slides on the movable rod 302k, and the bottom end of the sleeve 302h is fixedly connected to the support block 302f, and the support block 302f is fixedly connected to the adjustment rod 302b, and the corresponding sliding block 302b of the adjustment rod 302b is fixedly connected to the support block 302f. The sleeve 302h is movably connected in the arcuate groove 302a, which consists of an initial section 302c, a transition section 302d, and a terminal section 302e. When the annular plate 301a rotates, the arcuate groove 302a squeezes the adjustment rod 302b, causing the sleeve 302h to slide on the movable rod 302k. When the adjustment rod 302b is located at different positions among the initial section 302c, the transition section 302d, and the terminal section 302e, the movement distance of the sleeve 302h is limited.

[0062] Working principle: By setting the adjustment component 300, the powder discharge structure of the reaming drill bit 111 during rock breaking is further refined. When the pressure rod 201f moves downward, the limit strip 301c on the outer wall of the pressure rod 201f is correspondingly slidably connected in the deflection groove 301d, 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 adjustment rod 302b. At this time, the support block 302f and the sleeve 302h on the extrusion rod 201f move on the movable rod 302k, and the positioning block 302j on the movable rod 302k is slidably connected in 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 2 114, thereby crushing the broken rock mass and further improving the powder discharge efficiency.

[0063] Example 4

[0064] On the basis of the third embodiment, the following technical features are added: the chip discharge member 303 includes a spiral powder discharge groove 303a provided on the drill rod body 102, and a plurality of cutting grooves 303b are provided on the outer wall of the drill rod body 102. The spiral powder discharge groove 303a intersects with the cutting groove 303b, and the spiral powder discharge groove 303a divides the cutting surface into a plurality of crushing areas 303c. The depth of the second chip discharge groove 114 is greater than that of the cutting groove 303b. The spiral powder discharge groove 303a is wound around the drill rod body 102, and a plurality of crushing teeth 303d are fixedly connected to the crushing area 303c. The crushing teeth 303d are arranged in a stepped manner, and the crushing teeth 303d crush the gravel passing through the spiral powder discharge groove 303a.

[0065] Depend on Figures 2 to 7 It can be seen that the present invention ensures greater powder discharge efficiency and drilling intensity by cooperating with the spiral powder discharge groove 303a and the cutting groove 303b. Moreover, since the spiral powder discharge groove 303a divides the cutting groove 303b into multiple crushing zones 303c, during powder discharge, the crushed slag is discharged along the spiral powder discharge groove 303a. In addition, three sets of crushing teeth 303d are fixedly connected to the drill rod body 102, and the crushing teeth 303d are arranged in a stepped manner. In this way, the conveyed crushed rock is crushed to ensure efficiency during transportation.

[0066] Working principle: In summary, the present invention divides the cutting groove 303b into multiple crushing areas 303c through the spiral powder discharge groove 303a, and three groups of crushing teeth 303d are arranged in the crushing area 303c, and the crushing teeth 303d are arranged in a stepped manner. When the drill rod body 102 is broken during drilling, the larger broken rocks are crushed by the stepped crushing teeth 303d, so that the spiral powder discharge groove 303a can discharge powder more smoothly, thereby improving the working efficiency of the drill rod.

All technical solutions based on the principles of the present invention are within the scope of protection of the present invention. It should be noted that improvements and modifications that do not depart from the principles of the present invention are within the scope of protection of the present invention.
