[0019] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0020] like Figure 1As shown, the embodiment of the present disclosure proposes a bottom hole drill bit measurement while drilling device, including: a shell 1, a collection module 2 and a control module 3, the shell 1 is arranged in the inner cavity of the drill bit, and a fluid channel is arranged between the shell 1 and the inner cavity, the collection module 2 is arranged in the shell 1, and the collection module 2 includes: an acceleration detection unit 21, an angular velocity detection unit 22 and a temperature detection unit 23, the detection end of the temperature detection unit 23 passes through the shell 1, the control module 3 is arranged in the shell 1, and the first communication end of the control module 3 is respectively connected to the communication end of the acceleration detection unit 21, the communication end of the angular velocity detection unit 22 and the communication end of the temperature detection unit 23, the control module 3 is used for controlling the acceleration detection unit 21 to collect acceleration data, the angular velocity detection unit 22 to collect angular velocity data and the temperature detection unit 23 to collect temperature data according to a preset collection frequency when the rotation speed of the drill bit exceeds a preset rotation speed.

[0021] It can be understood that, since the shell 1 is arranged in the inner cavity of the drill bit, and a fluid channel is arranged between the shell 1 and the inner cavity, the acquisition module 2 is arranged in the shell 1, so that the acquisition module 2 can be arranged in the inner cavity of the drill bit using the shell 1, and collect real-time data of drilling without affecting the flow of fluid inside the drill bit. Moreover, since the first communication end of the control module 3 is respectively connected to the communication end of the acceleration detection unit 21, the communication end of the angular velocity detection unit 22 and the communication end of the temperature detection unit 23, when the rotation speed of the drill bit exceeds the preset rotation speed, the control module 3 can control the acceleration detection unit 21 to collect acceleration data, the angular velocity detection unit 22 to collect angular velocity data, and the temperature detection unit 23 to collect temperature data according to the preset acquisition frequency.

[0022] Therefore, through the integrated arrangement of the acquisition module 2 and the control module 3 in the shell 1, and the cooperation of the acquisition module 2 and the control module 3, real-time and stable acquisition of acceleration data, angular velocity data and temperature data of the drill bit during the drilling operation can be achieved, so as to accurately evaluate the rock parameters based on the acceleration data, angular velocity data and temperature data collected throughout the whole process, thereby meeting the needs of precise monitoring.

[0023] It should be noted that the housing 1 is used for the integrated arrangement of the acquisition module 2 and the control module 3, as well as the narrow space of the inner cavity of the drill bit. The specific type of the housing 1 can be set according to actual needs and is not limited to this.

[0024] Among them, the shell 1 is arranged in the drill bit and moves synchronously with the drill bit. The drill bit is used for drilling holes in the target rock formation. The specific type of the drill bit can be set according to actual needs and is not limited to this. For example, the drill bit can be a polycrystalline diamond composite sheet (Polycrystalline Diamond Compact, PDC) drill bit with an effective length of 24 cm, a maximum outer diameter of the cutting head of 12 cm, and an outer diameter of the steel pipe of 94 mm.

[0025] The acquisition module 2 is used to acquire acceleration data using the acceleration detection unit 21 , to acquire angular velocity data using the angular velocity detection unit 22 , and to acquire temperature data using the temperature detection unit 23 .

[0026] The specific type of the acceleration detection unit 21 can be set according to actual needs and is not limited thereto. For example, the acceleration detection unit 21 can be a three-axis vibration acceleration sensor with a measuring range of 0g-40g.

[0027] The specific type of the angular velocity detection unit 22 can be set according to actual needs and is not limited thereto. For example, the angular velocity detection unit 22 can be an angular velocity sensor with a measuring range of 0 rpm-500 rpm.

[0028] The specific type of the temperature detection unit 23 can be set according to actual needs, and there is no limitation on this. For example, the temperature detection unit 23 can be a temperature sensor with a measuring range of 0°C-120°C.

[0029] The control module 3 is used to control the acceleration detection unit 21 to collect acceleration data, the angular velocity detection unit 22 to collect angular velocity data, and the temperature detection unit 23 to collect temperature data according to a preset collection frequency when the drill bit rotation speed exceeds a preset rotation speed. The specific type of the control module 3 can be set according to actual needs and is not limited to this.

[0030] The preset speed can be set according to actual needs and there is no restriction on this. For example, the preset speed can be 100 rpm. That is to say, when the speed of the drill bit exceeds 100 rpm, the control module 3 controls the acceleration detection unit 21 to collect acceleration data, the angular velocity detection unit 22 to collect angular velocity data, and the temperature detection unit 23 to collect temperature data according to the preset acquisition frequency.

[0031] The preset acquisition frequency can be set according to actual needs and there is no limitation on this. For example, the preset acquisition frequency can be 1000 Hz, that is, the control module 3 controls the acceleration detection unit 21 to collect acceleration data, the angular velocity detection unit 22 to collect angular velocity data, and the temperature detection unit 23 to collect temperature data according to a frequency of 1000 Hz.

[0032] The control module 3 may obtain the drill bit rotation speed by communicating with the drill bit, or by the angular velocity detection unit 22 of this embodiment, or by other provided sensors, which is not limited.

[0045] It can be understood that since the first sealing ring 16 is sleeved in the first annular groove and the first sealing ring 16 abuts against the inner surface of the tube body 11, the outer surface of the first protruding tube 14 and the inner surface of the tube body 11 can be filled with the first sealing ring 16 to achieve a better sealing effect, thereby ensuring the safe and stable operation of the acquisition module 2 and the control module 3 in the tube body 11.
