[0026] The present invention will be further described below with reference to the accompanying drawings.
[0027] The utility model provides a drilling speed-increasing device and drilling equipment, which can effectively increase the speed of drilling work.
[0028] Figure 1 This is a schematic structural diagram of the impact assembly in the drilling speed-up device according to one embodiment of the present application when the impact assembly is in the first position; Figure 2 yes Figure 1 The enlarged structural diagram at A in the figure is shown in Figure 1. Figure 1-2 As shown, an embodiment of the present application provides a drilling speed-up device 1000. The drilling speed-up device 1000 includes a housing 100, a core shaft 200, and an impact member 300. The housing 100 includes a first sliding chamber 110. The first sliding chamber 110 extends along the length direction of the housing 100 and has an opening 111 at one end. A second sliding chamber 112 is provided on the inner side wall of the first sliding chamber 110. A fixed block 113 that moves along the length direction of the housing 100 is provided in the second sliding chamber 112. The core shaft 200 is disposed in the housing 100 and rotates relative to the housing 100 along its own axis. The core shaft 200 includes a through hole 210 disposed along the axial direction. The axial direction of the core shaft 200 is parallel to the length direction of the housing 100. The impact member 300 is disposed in the first sliding chamber 110. The impact member 300 is movably connected to the housing 100 along the length direction of the housing 100. The impact member 300 is connected to the fixed block 113; the impact member 300 includes a first position and a second position: in the first position, the through hole 210 is connected to the first sliding chamber 110; in the second position, the through hole 210 is connected to one end of the second sliding chamber 112 near the opening 111.
[0029] It should be noted that the second sliding chamber 112 is disposed at an end of the housing 100 proximal to the first sliding chamber 110. When the impact member 300 is in the first position, the through hole 210 communicates with the first sliding chamber 110. Liquid in the through hole 210 enters the end of the first sliding chamber 110 away from the opening 111. The liquid entering the first sliding chamber 110 exerts a force on the impact member 300 toward the opening 111. When the impact member 300 switches from the first position to the second position, the through hole 210 is no longer connected to the first sliding chamber 110, and the through hole 210 is connected to the end of the second sliding chamber 112 close to the opening 111, so that the drilling fluid in the through hole 210 enters the second sliding chamber 112 from the end of the second sliding chamber 112 close to the opening 111. After the fixed block 113 in the second sliding chamber 112 is subjected to the pressure of the drilling fluid, the fixed block 113 drives the impact member 300 to move in the direction away from the opening 111 of the first sliding chamber 110, so as to realize the switching of the position of the impact member 300. According to the drilling speed-up device 1000 of the embodiment of the present application, when the first through hole 210 of the core shaft 200 is connected to the first sliding chamber 110, the drilling fluid in the core shaft 200 can enter the first sliding chamber 110, so that the impact piece 300 of the first sliding chamber 110 moves to the first position along the length direction of the shell 100 (i.e., the axial direction of the core shaft 200) to knock the rock formation of the drilling well, and then the through hole 210 of the core shaft 200 is connected to the second sliding chamber 112, and the drilling fluid in the core shaft 200 enters the second sliding chamber 112 from one end of the second sliding chamber 112 close to the opening 111 of the first sliding chamber 110. In the second interactive chamber, the drilling fluid pushes the fixed block 113 in the second chamber to move along the length direction of the shell 100. Since the fixed block 113 is connected to the impact piece 300, the fixed block 113 drives the impact piece 300 to move from the first position to the second position. The impact piece 300 switches back and forth between the first position and the second position in the sliding chamber along the length direction of the shell 100, so that the impact piece 300 can knock on the drilled rock formation to generate additional impact force or vibration effect, which helps to break the rock, especially in deep formations, thereby increasing the drilling speed, shortening the drilling cycle, and reducing drilling costs.
[0030] In some optional embodiments, the core shaft 200 includes a first end and a second end disposed opposite each other in the axial direction, wherein the first end is adjacent to the opening 111 of the first sliding chamber 110, and the second end is away from the opening 111 of the first sliding chamber 110. The drilling speed-up device 1000 further includes a drill bit, a connector, and a plurality of straightening balls. The drill bit is coaxial with the first end, the connector is coaxially connected to the second end, and the plurality of straightening balls are disposed within the housing 100, between the core shaft 200 and the housing 100. The plurality of straightening balls are spaced apart circumferentially along the core shaft 200 and are in rolling contact with the outer wall of the core shaft 200.
[0031] like Figure 1-2 As shown, in some embodiments, the housing 100 includes a first pressurizing passage 120 and a first control valve 130. The first control valve 130 is disposed within the first pressurizing passage 120. The through hole 210 communicates with the first pressurizing passage 120. The impact member 300 includes a first communication passage 310. The first pressurizing passage 120 communicates with the first sliding chamber 110 via the first communication passage 310.
[0032] In this embodiment, when the first control valve 130 is opened, the drilling fluid in the through hole 210 enters the end of the first sliding chamber 110 away from the opening 111 through the first pressurizing passage 120 and the first connecting passage of the impact member 300. The drilling fluid entering the first sliding chamber 110 exerts a force on the impact member 300, pushing it to the first position, thereby causing the impact member 300 to impact the rock formation. When the position of the impact member 300 needs to be changed, the first control valve 130 is closed, preventing the drilling fluid in the through hole 210 from entering the first sliding chamber 110 through the first pressurizing passage 120.
[0033] like Figure 1-2 As shown, in some embodiments, the first pressurizing channel 120 includes a first liquid storage chamber 121 and a first liquid flow channel 122 that are interconnected. The first liquid storage chamber 121 is an annular chamber disposed around the outer circumferential wall of the core shaft 200. A through hole 210 is connected to the first liquid storage chamber 121, and the first control valve 130 is disposed within the first liquid flow channel 122. In the first position, the first liquid storage chamber 121 is connected to the first sliding chamber 110 via the first liquid flow channel 122.
[0034] In this embodiment, since the core shaft 200 is in a high-speed rotating state when the drilling speed-up device is in use, the first liquid storage chamber 121 is configured as an annular chamber surrounding the outer peripheral wall of the core shaft 200, so that the through hole 210 of the core shaft 200 can always maintain communication with the first liquid storage chamber 121. Specifically, the core shaft 200 can be provided with a radial liquid channel radially connected to the through hole 210. This radial liquid channel can always maintain communication with the first liquid storage chamber 121 while the core shaft 200 rotates axially relative to the housing 100, so that the transmission of drilling fluid is not affected by the rotation of the core shaft 200. The communication between the first boosting channel 120 and the first sliding chamber 110 is achieved by controlling the opening and closing of the first control valve 130 in the first liquid flow channel 122.
[0035] like Figure 2 As shown, in some embodiments, a first drainage channel 140 is provided on the side wall of the housing 100 . In the first position, the first sliding chamber 110 is in communication with the first drainage channel 140 .
[0036] In this embodiment, when the impact member 300 moves to the first position, the first sliding chamber 110 is connected to the first drainage channel 140, and the drilling fluid entering the first sliding chamber 110 through the through hole 210 and the first boosting channel 120 is discharged through the first drainage channel 140.
[0037] like Figure 3-4 As shown, in some embodiments, the housing 100 further includes a second pressurizing passage 150 and a second control valve 160. The second control valve 160 is disposed within the second pressurizing passage 150. One end of the second pressurizing passage 150 is connected to the through hole 210. The other end of the second pressurizing passage 150 is connected to an end of the second sliding chamber 112 near the opening 111.
[0038] In this embodiment, the second control valve 160 is opened, allowing the through hole 210 to communicate with the end of the second sliding chamber 112 near the opening 111 through the second boosting channel 150. The drilling fluid in the through hole 210 enters the second boosting chamber through the second boosting channel 150. The pressurized fluid entering the second boosting chamber exerts a force on the fixed block 113 away from the opening 111, causing the fixed block 113 to move the impact member 300 from the first position to the second position. When the impact member 300 needs to move from the second position to the first position, the second control valve 160 is closed, and the first control valve 130 in the first boosting channel 120 is opened. The drilling fluid in the through hole 210 enters the end of the first sliding chamber 110 away from the opening 111 through the first boosting channel 120 and the first connecting channel of the impact member 300. The drilling fluid entering the first sliding chamber 110 exerts a force on the impact member 300, pushing it to the first position. The switching of the impact member 300 between the first position and the second position is achieved by the opening and closing states of the first control valve 130 and the second control valve 160 , so that the impact member 300 repeatedly impacts the rock formation.
[0039] like Figure 4 As shown, in some embodiments, the second pressurizing channel 150 includes a second liquid storage chamber 151 and a second liquid flow channel 152 that are interconnected. The second liquid storage chamber 151 is an annular chamber disposed around the outer peripheral wall of the core shaft 200. The second control valve 160 is disposed in the second liquid flow channel 152. The second liquid storage chamber 151 is connected to the second sliding chamber 112 via the second liquid flow channel 152.
[0040] It should be noted that the inner wall of the second liquid storage chamber 151 and the outer wall of the core shaft 200 are combined to form a closed annular chamber, which is connected to the through hole 210 of the core shaft 200. This structural design of the second liquid storage chamber 151 allows the through hole 210 to always remain connected to the first liquid storage chamber 121 while the core shaft 200 rotates, so that the drilling fluid in the through hole 210 can enter the second liquid storage chamber 151, and by controlling the second control valve 160 in the second liquid flow channel 152 connected to the second liquid storage chamber 151, the through hole 210 is connected to the second sliding chamber 112 through the second boosting channel 150.
[0041] like Figure 4 As shown, in some embodiments, the fixing block 113 is provided with a second communication channel 1131 and a third control valve 1132 . The third control valve 1132 is provided in the second communication channel 1131 .
[0042] In this embodiment, when the impact member 300 moves from the second position to the first position, the fixed block 113 moves along the length direction of the shell 100 in the second sliding chamber 112. Since the second control valve 160 is in a closed state at this time, the drilling fluid in the second sliding chamber 112 will exert a force on the fixed block 113, hindering the sliding of the fixed block 113. At this time, the third control valve 1132 is opened, so that the drilling fluid in the second sliding chamber 112 is discharged through the second connecting channel 1131.
[0043] like Figure 4 As shown, in some embodiments, the housing 100 further includes a second drainage channel 170 and a one-way valve 180. The one-way valve 180 is disposed within the second drainage channel 170. One end of the second drainage channel 170 along its own extension direction communicates with the through hole 210. The other end of the second drainage channel 170 along its own extension direction communicates with the second sliding chamber 112.
[0044] In this embodiment, when the impact member 300 moves from the first position to the second position, the second drainage channel 170 communicates with the second sliding chamber 112, and the drilling fluid entering the second sliding chamber 112 through the second pressurizing channel 150 re-enters the through-hole 210 through the second drainage channel 170. It should be noted that when the impact member 300 moves from the first position to the second position, the third valve on the fixed block 113 is closed to avoid interfering with the normal operation of the second drainage channel 170. The one-way valve 180 ensures that drilling fluid cannot flow from the through-hole 210 through the second drainage channel 170 to the second sliding chamber 112, and can only flow from the second sliding chamber 112 back to the through-hole 210, thereby reducing the risk of failure caused by chaotic drilling fluid flow.
[0045] like Figure 1 and Figure 3As shown, in some embodiments, the first sliding chamber 110 is an annular sliding chamber coaxially arranged with the core shaft 200, and the impact member 300 is an annular sleeve, so that the impact member 300 impacts around the core shaft 200 and cooperates with the drill bit connected to the core shaft 200 to act on the rock formation, thereby improving drilling efficiency.
[0046] The embodiment of the present application also provides a drilling equipment, because it includes the drilling speed-up device 1000 of the above embodiments, it also includes all the beneficial effects of the above drilling speed-up device 1000, which will not be described one by one here.

In particular, the various technical features described in the various embodiments may be combined in any manner, provided no structural conflicts exist.
