[0003] To improve drilling speed and efficiency, especially for unconventional energy sources such as shale oil, more and more drilling teams are starting to use aggressive parameters, with mud pump displacements even exceeding 70L / s. In this drilling environment dominated by aggressive parameters, the repeated opening and closing of the rotary valve pulser not only increases the load on the rotary valve pulser, making it prone to failures such as shaft breakage or gearbox damage, but also wastes battery power, seriously affecting work efficiency.

[0040] To make the objectives, technical solutions, and advantages of this disclosure more apparent, exemplary embodiments according to this disclosure will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this disclosure, and not all embodiments of this disclosure. It should be understood that this disclosure is not limited to the exemplary embodiments described herein.

[0041] In the field of oil and gas exploration and development, rotary valve pulsers are commonly used during drilling (including directional drilling). These pulsers generate pulse signals by repeatedly opening and closing, thus enabling data transmission. Throughout the drilling process, the drilling modes used are mostly directional and combined drilling (i.e., rotary drilling). In combined drilling mode, directional drilling is not possible, meaning there is no need for rotary valve pulsers for data transmission. However, in combined drilling mode, the rotary valve pulser is still in a repeated opening and closing operation, resulting in wasted battery power and additional wear.

[0042] To improve drilling speed and efficiency, especially for unconventional energy sources such as shale oil, more and more drilling teams are starting to use aggressive parameters, with mud pump displacements even exceeding 70L / s. In this drilling environment dominated by aggressive parameters, the repeated opening and closing of the rotary valve pulser not only increases the load on the rotary valve pulser, making it prone to failures such as shaft breakage or gearbox damage, but also wastes battery power, seriously affecting work efficiency.

[0043] The above description, with reference to the accompanying drawings, describes a drilling mode control method, apparatus, device, storage medium, and program product according to embodiments of the present disclosure. By acquiring the state information of the directional probe, when the directional probe is in a rotating state, the drilling mode used by the drilling instrument is switched to a rotating mode. In the rotating mode, the rotary valve pulser does not send pulse waves and is in a normally open state with a discharge rate of about 70 L / s. It is not affected by mud impact, which reduces the load and helps to reduce damage to the rotary valve pulser and power waste.

[0044] In directional mode, the displacement is around 60L / s, which is the normal operating displacement and will not cause additional damage to the rotary valve pulser, thus greatly extending the service life of the rotary valve pulser. At the same time, it has significant energy-saving advantages, and the working time of a single battery can be extended to 360 hours.

[0045] To facilitate understanding of this embodiment, a detailed description of the drilling mode control method disclosed in this disclosure is provided first. The execution entity of the drilling mode control method provided in this disclosure is generally an electronic device with a certain computing capability. This electronic device may include, for example, a terminal device, a server, or other processing devices. The terminal device may be a user equipment (UE), mobile device, user terminal, terminal, cellular phone, cordless phone, personal digital assistant (PDA), handheld device, computing device, vehicle-mounted device, wearable device, etc. In some possible implementations, this drilling mode control method can be implemented by a processor calling computer-readable instructions stored in memory.

[0046] Example 1

[0047] like Figure 1 The diagram shows a flowchart of a drilling mode control method provided in an embodiment of this disclosure, the method comprising S101-S103:

[0048] S101: Obtain the rotational speed of the directional probe connected to the drilling instrument during a preset historical time period.

[0049] The drilling instrument is directly installed on the drill bit and takes measurements as the drill bit goes deeper into the ground. The preset historical time period can be set according to needs, such as within 10 seconds or within 1 minute.

[0050] Specifically, it includes the following steps:

[0051] Based on the fluxgate sensor installed on the drilling instrument, waveform data of the fluxgate sensor output during a preset historical time period is obtained; the waveform data is converted using a Schmitt trigger to obtain the rotational speed of the directional probe.

[0052] Modern fluxgate sensors typically consist of two windings mounted on a closed, highly permeable material. These two windings, along with the secondary side of an excitation transformer, form a bridge circuit. Figure 2As shown. When the external magnetic field is perpendicular to its input axis, the fluxgate output is 0. When the external magnetic field is not perpendicular to the input axis, the state of the magnetic core changes. On one side of the core, the external magnetic field and the excitation magnetic field are superimposed, increasing the saturation. On the other side, the external magnetic field and the excitation magnetic field are subtracted, decreasing the saturation. When the excitation magnetic field alternates and the core moves from the saturation region to the linear segment, pulse voltages of different magnitudes are induced on the two windings. The amplitude of these pulse voltages is related to the magnitude of the external magnetic field, and the frequency is twice the excitation frequency. The output of the fluxgate is amplified by bandpass, detected by phase-sensitive detector, and filtered to form a DC voltage. This voltage provides feedback current to the two windings of the fluxgate through a feedback resistor. The resulting magnetic field cancels out the external magnetic field, ensuring that the fluxgate always operates in a zero steady-state error state, thus giving the fluxgate high linearity.

[0053] The fluxgate sensor outputs a sinusoidal waveform (i.e., waveform data) as the drill bit rotates, with each 360° rotation constituting one cycle. Figure 3 As shown. A circuit (Schmitt trigger) is used to process the waveform, converting a sinusoidal waveform into a square wave, such as... Figure 4 As shown, by judging the number of rising or falling edges of the square wave waveform, the rotational speed of the directional probe within a preset historical time period can be determined.

[0054] S102: Based on the rotation speed of the directional probe during a preset historical time period, obtain the status information of the directional probe.

[0055] The state information is used to characterize whether the directional probe is in a rotating or stationary state. If the rotation speed reaches a stable state during a preset historical time period, the directional probe can be considered to be in a rotating state.

[0056] S103: When the status information indicates that the directional probe is in a rotating state, switch the drilling mode used by the drilling instrument to the rotating mode.

[0057] Specifically, the pulse signal sent from the directional probe to the rotary valve pulser is cut off, so that the rotary valve pulser is in standby mode; the drilling mode used by the drilling instrument is switched to rotary mode, in which the rotary valve pulser is in standby mode.

[0058] Optionally, this embodiment also provides a protection measure, including:

[0059] After switching the drilling mode used by the drilling instrument to the rotary mode, the status information of the directional probe in the rotary mode is obtained. Specifically, in the rotary mode, the rotation speed information of the directional probe in the preset historical time period is obtained; based on the rotation speed information, the status information of the directional probe in the rotary mode is obtained.

[0060] When the status information in the rotation mode indicates that the directional probe is stationary, the directional probe is controlled to send a pulse signal to the rotary valve pulser, and the rotation mode is switched to the directional mode.

[0061] The process of controlling the directional probe to send a pulse signal to the rotary valve pulse generator includes: controlling the rotary valve pulse switch to be in the open state, and the directional probe sending a pulse signal to the rotary valve pulse generator through the rotary valve pulse switch.

[0062] Example 2

[0063] This disclosure provides a drilling mode control method applied to a main control microcontroller, the method comprising:

[0064] A fluxgate sensor-based identification module is installed on the drilling instrument, and the main control microcontroller uses the identification module to determine whether the directional probe is rotating.

[0065] Modern fluxgate sensors typically consist of two windings mounted on a closed, highly permeable material. These two windings, along with the secondary side of an excitation transformer, form a bridge circuit. Figure 2 The diagram shows the working principle of a fluxgate sensor. When the external magnetic field is perpendicular to its input axis, the fluxgate output is 0. When the external magnetic field is not perpendicular to the input axis, the state of the magnetic core changes. On one side of the core, the external magnetic field and the excitation magnetic field are superimposed, increasing the saturation. On the other side, the external magnetic field and the excitation magnetic field are subtracted, decreasing the saturation. When the excitation magnetic field alternates and the core moves from the saturation region to the linear segment, pulse voltages of different magnitudes are induced on the two windings. The amplitude of these pulses is related to the magnitude of the external magnetic field, and the frequency is twice the excitation frequency. The output of the fluxgate is amplified by bandpass, detected by phase-sensitive detector, and filtered to form a DC voltage. This voltage provides feedback current to the two windings of the fluxgate through a feedback resistor. The resulting magnetic field cancels out the external magnetic field, ensuring that the fluxgate always operates in a zero steady-state error state, thus giving the fluxgate high linearity.

[0066] The fluxgate sensor outputs a sinusoidal waveform (i.e., waveform data) as the drill bit rotates, with each 360° rotation constituting one cycle. Figure 3 As shown in the diagram, a circuit (Schmitt trigger) is used to process the waveform, converting a sinusoidal waveform into a square wave. The waveform conversion diagram is shown below. Figure 4 As shown, by judging the number of rising or falling edges of the square wave waveform, the rotational speed of the directional probe within a preset historical time period can be determined.

[0067] With the directional probe stationary, the drilling instrument activates directional mode at a displacement of approximately 60 L / s, which is within normal operating range and will not cause additional damage. This significantly extends the lifespan of the rotary valve pulser. Simultaneously, it offers significant energy savings, extending the single-battery operating time to 360 hours, effectively reducing rotary valve pulser maintenance and battery costs, and enabling the rational, efficient, and low-cost use of the instrument string. In directional mode, the directional probe is stationary and can be used for inclination measurement; therefore, the rotary valve pulser needs to be in normal operating condition (repeatedly opening and closing) to achieve data transmission.

[0068] When the directional probe is rotating, the drilling instrument activates the rotation mode. The rotary valve pulser does not send pulse waves, the mud discharge rate is greater than 70 L / s, and the rotary valve pulser remains in a normally open state, unaffected by mud impact and less prone to damage. In rotation mode, the directional probe rotates and cannot be used for inclination measurement; therefore, the rotary valve pulser is in standby mode. However, setting the standby state to "off" can easily cause the rotary valve pulser to become clogged and suffer significant erosion damage. Therefore, in this embodiment, the standby state is set to "normally open" to protect the rotary valve pulser from mud impact and prevent damage.

[0069] Design Concept: The main control microcontroller collects data from the fluxgate sensor, processes it using an algorithm to obtain the rotational speed of the directional probe, and determines whether the speed is stable within a certain time. If stable, it indicates that the directional probe is rotating and enters rotation mode. At this time, the main control microcontroller cuts off the DATA signal (pulse signal) of the directional probe. The directional probe cannot output the DATA signal to the rotary valve pulser, and the rotary valve pulser enters standby mode (i.e., normally open). When the rotation mode stops (i.e., the directional probe stops rotating), the rotation detection module immediately responds, opening the rotary valve pulse switch, allowing the directional probe to send the DATA signal to the rotary valve pulser normally.

[0070] Anomaly Handling: In this embodiment, the pulse switch is designed to be normally closed. When the rotation detection module detects that the rotation mode has stopped, the rotary valve pulser is in normal working condition and does not affect the normal transmission of the pulse signal.

[0071] Example 3

[0072] In one or more embodiments, this embodiment provides an application example, specifically a drilling mode control system, including a main control microcontroller circuit, a control circuit, and a fluxgate processing circuit, wherein:

[0073] The main control microcontroller circuit acquires data from the fluxgate sensor, i.e., sinusoidal waveform data, and uses a Schmitt trigger to convert the waveform data to obtain the rotational speed of the directional probe; it then determines whether the rotational speed of the directional probe is stable within a preset historical time period. If it is stable, it indicates that the directional probe is rotating.

[0074] Optionally, the main control microcontroller circuit includes a rotation detection module.

[0075] Rotation Detection Module: This module detects whether the directional probe is rotating in rotation mode. If the directional probe stops rotating, the rotary valve pulse switch is activated, allowing the directional probe to send pulse signals to the rotary valve pulse generator, which then enters its operating mode. The rotary valve pulse switch is preferably designed to be normally closed. When the rotation detection module detects a circuit malfunction, it activates the rotary valve pulse switch, ensuring the rotary valve pulse generator operates normally without affecting the normal transmission of pulse signals.

[0076] Control circuit: Upon receiving a cut-off command from the main control microcontroller circuit, the circuit cuts off the pulse signal sent from the directional probe to the rotary valve pulser, entering rotation mode. At this time, the pulse signal from the directional probe cannot be output to the rotary valve pulser, and the rotary valve pulser enters standby mode.

[0077] Fluxgate processing circuit: outputs sinusoidal waveform data to characterize whether the directional probe is rotating.

[0082] The switching module 503 is used to switch the drilling mode used by the drilling instrument to the rotation mode when the status information indicates that the directional probe is in a rotating state. In the rotation mode, the rotary valve pulser is in standby mode.
