Background
With the continuous development of the oil and gas exploration industry, drilling tools are widely applied. Due to the fact that the design applicable working condition parameter range of the drilling tool is limited, and the actual service life of the drilling tool is closely related to the working condition during drilling, the drilling tool is influenced by complex environment and severe working conditions in the underground drilling process, and the drilling tool is easily damaged. If the drilling tool is damaged in the well, a technician needs to obtain data of the downhole working environment for analysis so as to optimize the lifting performance of the drilling tool, and the rotating speed of the drilling tool is the most important data of the downhole working environment.
At present, the measurement of the rotating speed of the drilling tool is mainly realized by a method of a fluxgate, a Hall switch sensor or a permanent magnet. When the fluxgate is used for measuring the rotating speed, the fluxgate component is required to be arranged on the drilling tool to be measured or the short section which is rigidly connected with the upper part and the lower part of the drilling tool to be measured, the circumference change magnetic field measured on the fluxgate is converted into the circumference change times by utilizing the north-south polarity characteristic of the earth magnetic field, and the circumference change times in unit time is used as the rotating speed of the drilling tool. The method for measuring the rotating speed through the fluxgate needs to add a measuring short section on the drilling tool, so that the cost is high, and when the geomagnetic field is parallel to the rotating shaft of the rotating speed measuring short section (namely, the geomagnetic field is perpendicular to the fluxgate to measure the short section), the situation that the fluxgate pulse output is zero can occur, namely, the azimuth dead zone of the drilling tool occurs during the measurement, so that the measured rotating speed is inaccurate.

Referring to fig. 1, a block diagram of a system for measuring a rotational speed of a drilling tool according to an embodiment of the present invention is shown in fig. 1, where the apparatus may include: the device comprises a rotating speed measuring module 101, a main control processing module 102, a power management module 103, a temperature measuring module 104, a data storage module 105, an RTC clock module 106, a wireless data transmission module 107, a low power consumption management module 108 and a high temperature resistant battery 109.

The temperature measurement module 104 realizes the measurement of the ambient temperature and the cut-off function of the main power circuit, and when the measured ambient temperature exceeds the highest temperature resistance value of the drilling tool rotating speed measurement system, the temperature measurement module 104 can directly cut off the power supply through an internal hardware circuit, so that the rear module can be powered off, and the rear module is protected from being damaged by high temperature. Meanwhile, the temperature measurement module 104 may also provide an ambient temperature value for the master processing module 102.
The RTC clock module 106 provides a real-time clock for the main control processing module 102, so as to ensure accurate operation time of the drilling tool rotation speed measuring system.

In practical application, the drilling tool rotation speed measuring system can be installed at a position where the drilling tool rotates, such as a main shaft of the drilling tool, so that the drilling tool rotation speed measuring system can operate along with the rotation of the drilling tool, and therefore the operation rotation speed information can be obtained.
The method for measuring the rotational speed of the drilling tool according to the embodiment of the present application is described below with reference to the system for measuring the rotational speed of the drilling tool shown in fig. 1.
Referring to fig. 2, a flow chart of a method for measuring the rotational speed of a drilling tool according to an embodiment of the present application is provided, and the method may be applied to the system for measuring the rotational speed of a drilling tool shown in fig. 1, wherein the drilling tool may be a drilling tool.
As shown in fig. 2, the method may include the steps of:
and S21, after the drilling tool rotating speed measuring system is awakened from the dormant state, determining the rotating period of the drilling tool.
As an embodiment, the rotation speed measuring module, the data storage module and the wireless data transmission module in the drilling tool rotation speed measuring system in the dormant state are all in the power-off state and cannot work, so that before the rotation speed of the drilling tool is measured, the drilling tool rotation speed measuring system needs to be ensured to be in the wake-up state.
In the embodiment of the application, after the drilling tool rotation speed measuring system is awakened from the dormant state, the rotation speed of the drilling tool can be measured through the rotation speed measuring module.
S22, measuring a plurality of first acceleration values of the drilling tool in the speed direction in one rotation period.
And S23, fitting the plurality of first acceleration values to obtain a fitting curve.
And S24, if the fitting curve is determined to meet the change of the sine curve, measuring a second centrifugal acceleration value of the drilling tool.
And S25, calculating the actual rotating speed value of the drilling tool by adopting a preset speed calculation formula according to the second centrifugal acceleration value.
The following description is made collectively for S21-S25:
as one example, the rotational speed measurement module may include an acceleration sensor. The acceleration sensor may be a two-axis acceleration sensor or a three-axis acceleration sensor.
In practical application, in order to ensure the accuracy of the measured result of the drilling tool rotating speed measuring system, when the drilling tool rotating speed measuring system is installed on a drilling tool, it is required to ensure that an X axis and a Y axis of an acceleration sensor are kept perpendicular to the length direction of the drilling tool, wherein the X axis is consistent with the tangential direction (namely the speed direction) of the rotating track of the drilling tool and is used for collecting the acceleration of the drilling tool in the speed direction so as to detect the posture of the drilling tool based on the acceleration in the speed direction and further judge the change of the posture of the drilling tool in a well, and the Y axis is perpendicular to the axis of the drilling tool and is used for measuring the centrifugal acceleration value of the drilling tool during rotation. If the acceleration sensor is a three-axis acceleration sensor, the Z axis needs to be ensured to be parallel to the length direction of the drilling tool during installation.
In the embodiment of the present application, the following formula (1) may be used to calculate the velocity value of the drilling tool according to the centrifugal acceleration value of the drilling tool during rotation, which is acquired by the acceleration sensor Y axis:
N＝(89400*RCF/r)^1/2
wherein, RCF: representing a centrifugal acceleration value in units of gravitational acceleration g; r: represents the radius of the drilling tool in centimeters; n: representing the rotation speed of the drilling tool in revolutions per minute; 89400 are calculation constants.
The acceleration value obtained from the Y axis of the acceleration sensor is substituted into the formula, and the rotating speed value in the current drilling tool operation process can be calculated.
However, after the drilling tool rotation speed measuring system is installed on the drilling tool based on the above manner, when the drilling tool is placed parallel to the ground, the Y axis of the acceleration sensor may be perpendicular to the ground, and at this time, the Y axis may output an acceleration value of 1g, and if the acceleration value output by the Y axis is input into formula (1) to calculate the rotation speed of the drilling tool, the obtained rotation speed value may be abnormal data. In addition, the drilling tool can all lead to acceleration sensor's each axle to produce the acceleration value because of rocking in transportation, handling and the installation, also can calculate the rotational speed data that obtains unusually equally, for solving the appearance of these unusual rotational speed data, among the drilling tool rotational speed measuring method that this application embodiment provided, utilize acceleration sensor X axle to detect the gesture of drilling tool earlier, if judge that the drilling tool is in rotatory gesture, go to acquire the acceleration value of Y axle measurement again, the rotational speed value of calculating like this is accurate rotational speed promptly.
In the embodiment of the application, the method for detecting the posture of the drilling tool by utilizing the X axis is to continuously acquire the acceleration value of the X axis. Because the continuous acceleration values acquired by the X axis have a sine wave-like variation trend during the normal rotation of the drilling tool. And the data of the X axis caused by shaking in the transportation, carrying and installation processes is non-sine wave irregular data waveform, so when the fact that the sine wave-like data of the X axis of the acceleration sensor is changed is detected, the fact that the drilling tool starts to rotate can be determined.
In the embodiment of the present application, before the acceleration values of the X axis are continuously obtained, a sampling period of the drilling tool may be determined, so as to continuously acquire the acceleration values of the X axis in the sampling period, where the acceleration values of the X axis, that is, a first speed value of the drilling tool in a speed direction, hereinafter referred to as a first speed value.
As an alternative implementation, the sampling period may be determined in real time. Specifically, a first centrifugal acceleration value of the drilling tool, that is, an acceleration value of the Y axis, may be measured by using the acceleration sensor, and then the first speed value of the drilling tool is calculated according to the first centrifugal acceleration value by using a first speed calculation formula, that is, formula (1), where the reciprocal of the first speed value is used as a sampling period of the drilling tool, where the sampling period is also a rotation period of the drilling tool, and the rotation period is a time period of one rotation of the drilling tool.
As another alternative, the sampling period may also be preset and stored in a data storage module in the drilling tool rotational speed measurement system, so that the sampling period can be directly acquired from the data storage module when being determined. As an embodiment, the pre-stored adoption period may be set according to a historical working record of the drilling tool, such as an average rotation period determined according to the historical working record of the drilling tool.
After the sampling period is determined, a plurality of first acceleration values of the drilling tool may be continuously acquired during one sampling period. After the sampling of the first acceleration values is completed, the plurality of first acceleration values can be fitted to obtain a fitting curve, whether the fitting curve meets the change of a sinusoidal curve or not is judged, and if the fitting curve meets the change of the sinusoidal curve, the current drilling tool is determined to be in a rotating posture, and then the rotating speed is measured.
As an embodiment, when determining whether the fitted curve satisfies the sinusoidal variation, the fitted curve may be compared with a preset rotation posture model, and whether the sinusoidal variation is satisfied may be determined according to the comparison result.
In practical applications, because the drilling tool operates at different inclination angles, the curves generated according to the acceleration values of the X-axis may differ, but all exhibit sinusoidal variations. Therefore, the preset rotation attitude model can be composed of a plurality of standard curves, wherein different standard curves are formed by fitting acceleration values of the X axis when the drilling tool works normally under different inclination angles. Based on this, when judging whether the fitting curve fit-synthesized according to the plurality of first acceleration values satisfies the change of the sinusoidal curve, the fitting curve can be compared with each standard curve, and when the error between the fitting curve and any standard curve is smaller than a preset value, it can be determined that the fitting curve satisfies the change of the sinusoidal curve, wherein the preset value can be a value set according to actual conditions.
Further, as an embodiment, since the drilling tool may generate vibration during the operation process, and the vibration may cause interference fluctuation in the acquired first acceleration values, before generating a fitting curve according to a plurality of first acceleration values or before determining whether the fitting curve satisfies sinusoidal curve change, a filtering process is performed by using a software algorithm to filter the interference fluctuation.
After the drilling tool is determined to be in the rotating posture, the acceleration value of the Y axis of the acceleration sensor (namely, the second centrifugal acceleration value) can be obtained again, and then the second centrifugal acceleration value is substituted into the formula (1), so that the actual rotating speed value of the drilling tool is obtained through calculation.
The embodiment of the application provides a method for measuring the rotating speed of a drilling tool, when a system for measuring the rotating speed of the drilling tool measures the rotating speed of the drilling tool, the sampling period of the drilling tool is determined firstly, then a plurality of first acceleration values of the drilling tool in the speed direction are collected in the sampling period, a fitting curve is obtained by fitting the first acceleration values, whether the drilling tool is in a rotating posture or not is determined by judging whether the fitting curve meets the change of a sine curve or not, when the fitting curve is determined to meet the change of the sine curve, the drilling tool is determined to be in the rotating posture, the centrifugal acceleration value of the drilling tool is collected at the moment, and then the actual rotating speed of the drilling tool is determined according to the centrifugal acceleration value. By the method, the abnormal rotating speed of the drilling tool can be effectively avoided because the drilling tool is in the non-rotating posture, and the accuracy of the rotating speed of the drilling tool is ensured.
In another embodiment of the present application, on the basis of the method for measuring the rotational speed of a drilling tool shown in fig. 2, after the system for measuring the rotational speed of a drilling tool is awakened from the sleep state, before determining a sampling period of the drilling tool, the method may further include:
and determining whether the preset drilling tool rotating speed measuring condition is met or not, and if the preset drilling tool rotating speed measuring condition is met, executing the step of determining the sampling period of the drilling tool.
As an example, as shown in fig. 3, determining whether the preset drill rotation speed measurement condition is satisfied may include:
s31, obtaining configuration information of the drilling tool rotating speed measuring system stored in the data storage module, wherein the configuration information comprises mode information of the drilling tool rotating speed measuring system, the mode information comprises a working mode and a standby mode, if the mode information is the working mode, S33 is executed, and if the mode information is the standby mode, S32 is executed.
S32, detecting whether the drilling tool rotating speed measuring system has wireless data interaction, if no wireless data interaction exists, executing S33, and if no wireless data interaction exists, executing S34.
And S33, determining that the preset drilling tool rotating speed measuring condition is met.
Further, if the mode information is error information, where the error information is mode information that is neither the working mode nor the standby mode, the mode information is changed to the standby mode and then stored in the data storage module, and the data storage module enters the sleep state.
Further, the method for measuring the rotation speed of the drilling tool provided by the embodiment of the application can further include:
s34, determining whether the interactive data is a configuration parameter command or an acquisition storage record command, if so, executing S35, if so, executing S36, and if so, executing S37.
The abnormal data refers to data that is neither a configuration parameter command nor a get record storage command.
And S35, storing the configuration information carried in the configuration parameter command, and executing S37 after the storage is finished.
S36, the stored working record information of the drilling tool is obtained from the data storage module, the working record information is transmitted to external equipment through the wireless data transmission module, and S37 is executed after the data transmission is finished.
And S37, entering a dormant state.
In the embodiment of the application, the drilling tool rotating speed measuring system is switched from the dormant state to the awakening state and then to the dormant state according to the periodic continuity, the rotating speed measuring module, the data storage module and the wireless data transmission module are all in the power-off state in the dormant state, and the master control processing module and the RTC clock module are in the low power consumption mode, so that the overall power consumption of the drilling tool rotating speed measuring system is reduced, and the long-time running of the drilling tool rotating speed measuring system is ensured.
Further, in another embodiment of the present application, on the basis of any of the above embodiments, before the step of determining the sampling rotation period of the drilling tool is performed, the method may further include:
detecting the current environment temperature, if the current environment temperature is determined to be less than or equal to the preset highest temperature-resistant temperature, executing the step of determining the sampling period of the drilling tool, and if the current environment temperature is determined to be greater than the highest temperature-resistant temperature, cutting off the power supply of the drilling tool rotating speed measuring system.
