Description

Technical Field

[0001] The present application relates to the field of drilling, and in particular to a method and device for determining the control effect of a steering tool face of a rotary steering tool. Background Art

[0002] According to the guiding principle, rotary steering tools can be divided into two categories: push-type rotary steering and pointing rotary steering. Push-type rotary steering relies on the lateral force generated by pushing against the well wall to create deflection guidance. Pointing rotary steering uses an internal bias mechanism to provide the drill bit with an inclination angle inconsistent with the wellbore axis to produce a guiding effect, and does not rely on the wellbore wall and geological environment to guide drilling. Pointing rotary steering is divided into static pointing rotary steering and dynamic pointing rotary steering according to the working mode of the internal bias mechanism. The static bias pointing rotary steering relies on applying thrusts in different directions to the core shaft to produce controllable bending to achieve a directional effect. The dynamic pointing rotary steering relies on the internal dynamic bias mechanism to drive the drill bit to offset in a controllable direction. Directional drilling is achieved.

[0003] The steering tool face is the offset direction of the rotating steering drill bit, which determines the deflection direction of the drilling trajectory. The steering rate refers to the proportion of the time of the fixed steering tool face in a drilling cycle to the drilling cycle. During the non-fixed steering tool face time, the tool face is evenly distributed in the range of 0-360°, thereby maintaining the original trajectory drilling. The magnitude of the steering rate determines the curvature of the drilling trajectory, that is, the magnitude of the inclination rate. The fixed steering tool face is called the steering mode, and the non-fixed tool face is called the direct drilling mode.

[0004] In directional drilling, field operators set appropriate tool faces and steering rates for rotary steering tools according to trajectory design requirements. The rotary steering tool switches between steering mode and direct drilling mode according to the steering rate. The required tool face changes in real time according to the mode switching.

[0005] Affected by factors such as uneven formations, vibration and impact, the offset direction of the drill bit, that is, the control of the steering tool face, is not always the same as the set tool face. If the control of the steering tool face deviates from the set tool face for a long time, the directional trajectory will deviate from the preset track, causing the operation to fail. On-site operators need to adjust the operation parameters in a timely manner according to the tool face control situation. During the drilling process, the data of the instrument tools are usually transmitted to the ground through mud signals, and the communication rate is low. The ground personnel can only get a set of data within a few minutes. The target tool face will change over time in the direct drilling mode, resulting in the ground personnel being unable to accurately judge whether the actual tool face is consistent with the target tool face, and unable to take corresponding measures in time, which may seriously lead to operation failure. Summary of the invention

DETAILED DESCRIPTION

[0026] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] Figure 1 FIG. 1 is a flow chart showing a method for determining a steering tool surface control effect of a rotary steering tool according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps: Step S101, 0-360° is divided into a preset number of sectors, and two counters are set for each sector, wherein the two counters of each sector correspond to the guide mode and the direct drilling mode respectively, and the initial count value of each counter is 0.

[0028] Specifically, the number of sectors to be divided can be determined according to application requirements and accuracy requirements. If a higher angular resolution is required, more sectors can be selected (such as 72 sectors, one sector every 5 degrees); if the accuracy requirement is not high, fewer sectors can be selected (such as 12 sectors, one sector every 30 degrees). Of course, other numbers can also be selected, for example, 16 sectors, that is, 0-360° is evenly divided into 16 sectors, such as Figure 5 Each sector corresponds to an angle range and a unique sector index (also called sector number), for example, the sector index is 1-16.

[0029] In the steering mode, the tool face angle of the steering tool remains fixed, such as Figure 2 As shown in FIG3 , in the straight drilling mode, the tool face angle of the steerable tool changes at a uniform speed within the range of 0-360°, as shown in FIG3 . Therefore, after dividing 0-360° into a preset number of sectors, two counters need to be set for each sector. The two counters of each sector correspond to the steer mode and the straight drilling mode, respectively, and the initial count value of each counter is 0. For example, SectorCount_Steer(i) represents the counter of the ith sector in the steer mode, and SectorCount_Straight(i) represents the counter of the ith sector in the straight drilling mode.

[0030] In order to facilitate the subsequent use of the count values, a data structure can be created for each sector to save the count values ​​of the two counters. An array or list can be used to represent all sectors, where each element is a structure or tuple containing two integers, representing the count values ​​in the guided mode and the direct drilling mode respectively.

[0031] Step S102, reading the tool face angle and the working mode corresponding to the guide tool face, determining the sector to which the tool face angle belongs, and updating the count value of the counter corresponding to the working mode in the sector to which the tool face angle belongs.

[0032] The tool face angle of the current steering tool face and the working mode it is in are read from the sensor or other data source, where the working modes include steering mode and direct drilling mode, and the tool face angle refers to the angular position of the steering tool relative to a reference direction (gravity direction or geomagnetic field direction), usually in degrees and between 0 and 360 degrees. Combined with the sector angle range of each sector, determine the sector to which the tool face angle belongs, or divide the tool face angle by the angular width of each sector, and then round it to get the sector index.

[0033] After determining the sector to which the tool face angle belongs and the current working mode of the steering tool, the value of the counter corresponding to the working mode in the sector is increased. If the working mode is the steering mode, the count value of the counter of the corresponding sector in the steering mode is increased by 1; if the working mode is the direct drilling mode, the count value of the counter of the corresponding sector in the direct drilling mode is increased by 1.

[0034] Taking 0-360° being evenly divided into 16 sectors as an example, if the tool face angle is 10° and the working mode is the steering mode, the count value of the counter in the steering mode of the first sector is increased by 1, that is, SectorCount_Steer(1) is increased by 1.

[0035] Reading the tool face angle and the working mode corresponding to the steering tool face is a continuous process, so it will be updated after each reading. The reading frequency can be set as needed.

[0036] Step S103, calculates the first tool face angle and the first guidance rate of the guidance tool face in the guidance mode according to the count value of the counter in the guidance mode of each sector within the preset time period, and calculates the second guidance rate corresponding to the guidance tool face in the direct drilling mode according to the count value of the counter in the direct drilling mode of each sector within the preset time period.

[0037] According to the actual operation situation, determine the time period for calculating the statistics, that is, the preset time period, such as every minute, every hour, every day, and of course other time periods. Specifically, under ideal conditions, the steering tool is oriented all the time in the steering mode, the steering rate is 100%, and the tool face angle is the set steering direction. The steering rate in the direct drilling mode is 0, and there is no fixed steering angle. Due to the influence of control errors, the tool face angle in the steering mode is not constant. The actual steering direction is the integral and determination of the tool face angle over time, and the steering rate is determined by the distribution probability of the tool face angle over time. Therefore, it is necessary to calculate the equivalent steering direction and steering rate in the steering mode, and the equivalent steering direction and steering rate in the direct drilling mode. Here, the equivalent steering direction and equivalent steering rate in the steering mode can be defined as the first tool face angle and the first steering rate. The equivalent steering direction and equivalent steering rate in the direct drilling mode are defined as the second tool face angle and the second steering rate.

[0038] Therefore, at the end of the preset time period, the count values ​​of the counters in the two modes in all sectors are collected, and for each sector, there are final values ​​of the two counters. Then, according to the count values ​​of the counters in the steering mode of each sector in the preset time period, the first tool face angle and the first steering rate of the steering tool face in the steering mode are calculated, and according to the count values ​​of the counters in the direct drilling mode of each sector in the preset time period, the second steering rate corresponding to the steering tool face in the direct drilling mode is calculated. Wherein, the steering rate is the ratio of the time of the steering mode to the total time in a period T, such as Figure 4 The steering direction refers to the angle of the tool face in steering mode.

[0039] In addition, the second tool face angle corresponding to the steering tool face in the direct drilling mode may be calculated according to the count value of the counter in the direct drilling mode of each sector within a preset time period.

[0040] For example, the first tool face angle, the first guide rate, the second tool face angle, and the second guide rate may be calculated using the following formulas:

[0041]

[0042]

[0043]

[0044]

[0045] Wherein, x represents the steering mode and the direct drilling mode respectively, i represents the i-th sector, and the preset number is set to N; Indicates the count value of the counter of the i-th sector in the x mode, Indicates the total value of the counter for a preset number of sectors in x mode, is the angle value of the central angle of the i-th sector, and is the middle value, Indicates the tool face angle corresponding to the guide tool face in x mode, It represents the steering rate corresponding to the steering tool face in x mode.

[0046] Step S104, determining the control effect of the steerable tool face according to the second steerability ratio, the first tool face angle and the first steerability ratio.

[0047] After the second guidance rate, the first tool face angle and the first guidance rate are calculated according to step S103, the steering tool face control effect can be judged according to the second guidance rate, the first tool face angle and the first guidance rate. Here, the main purpose is to judge the steering tool face control stability. For example, a threshold value can be set, and the second guidance rate, the first tool face angle and the first guidance rate can be compared with the corresponding threshold values ​​respectively, and the steering tool face control effect can be judged according to the comparison result.

[0048] Specifically, the control effect of the steering tool surface may be determined by: determining whether the second steering rate is greater than a second steering rate determination threshold; If the second guidance rate is greater than the second guidance rate determination threshold, determining that the steering tool face control effect in the direct drilling mode is the first control effect; Determining whether the first guidance rate is greater than or equal to a first guidance rate determination threshold, and determining whether a difference between the first tool face angle and a preset target tool face angle is less than or equal to a preset deviation threshold; If the first guidance rate is less than the first guidance rate determination threshold, and / or the difference between the first tool face angle and the preset target tool face angle is greater than the preset deviation threshold, it is determined that the guidance tool face control effect in the guidance mode is the first control effect.

[0049] In straight drilling mode, the steering ratio should ideally be 0. Therefore, the steering tool face control effect can be judged according to the steering ratio in straight drilling mode. If the steering ratio in straight drilling mode (the second steering ratio, SteerRatio_straight) is greater than the second steering ratio determination threshold (setpoint0), where the second steering ratio determination threshold is usually set to 40%-50%, it is determined that the steering tool face control stability is poor, that is, the steering ratio and the steering tool face control stability are poor (first control effect), and the first alarm information can be output, for example, the fault flag is set to 1. If the second steering ratio is less than or equal to the second steering ratio determination threshold, it can be determined that the steering tool face control stability is good (second control effect) in straight drilling mode, and the fault flag is set to 0. For example, it can be implemented by the following code: if (SteerRatio_straight>setpoint0) Flagstability =1 else Flagstability =0 In the steering mode, the steering rate should ideally be 100%, and the tool face angle of the steering tool face is the set tool face angle. Therefore, the first steering rate can be compared with the first steering rate determination threshold (setpoint1), and the difference between the first tool face angle and the preset target tool face angle is calculated, and the difference is compared with the preset deviation threshold. If the first steering rate is less than the first steering rate determination threshold, and / or the difference is greater than the preset deviation threshold, it is determined that the steering tool face control stability is poor (first control effect), that is, the steering rate and the steering tool face control stability are poor, and the fault flag is set to 2.

[0050] If the first guidance rate is greater than or equal to the first guidance rate determination threshold, and the difference is less than or equal to the preset deviation threshold, it is determined that the steering tool surface control stability is good (second control effect), and the fault flag is set to 0. For example, it can be implemented by the following code: if (SteerRatio_steer≥setpoint1&&abs( Toolface_steer-Toolface_desired )≤setpoint2) Flagstability =0 else Flagstability =2 In the above, the stability of the guiding tool face in the direct drilling mode and the guiding mode is judged respectively. In addition, the present application can also combine the direct drilling mode and the guiding mode to give a stability judgment result. That is to say, when it is judged that the second guiding rate is less than or equal to the second guiding rate judgment threshold, it is further judged whether the first guiding rate is greater than or equal to the first guiding rate judgment threshold, and whether the difference between the first tool face angle and the preset target tool face angle is less than or equal to the preset deviation threshold. If the first guiding rate is less than the first guiding rate judgment threshold, and / or the difference between the first tool face angle and the preset target tool face angle is greater than the preset deviation threshold, then the guiding tool face control effect is determined to be the first control effect, and the third alarm information is output, for example, the fault flag is set to 3.

[0051] This allows staff to perform fault analysis through the fault flag.

[0052] In an optional implementation manner of the present application, after determining that the control effect of the steering tool face is the second control effect, the second steering rate corresponding to the steering tool face in the direct drilling mode can also be calculated according to the count value of the counter in the direct drilling mode of each sector within a preset time period, such as calculating the second steering rate using the formula shown in step S103, and then calculating the comprehensive tool face angle and comprehensive steering rate corresponding to the steering tool face of the rotary steering tool according to the first tool face angle, the first steering rate, the second tool face angle and the second steering rate, wherein the comprehensive tool face angle reflects the actual tool face angle of the steering tool, and the comprehensive steering rate reflects the actual steering rate of the steering tool. For example, the comprehensive tool face angle and comprehensive steering rate can be calculated using the following formula:

[0053] in, is the first guidance rate, is the first tool face angle, is the second guidance rate, is the second tool face angle, is the comprehensive tool face angle, is the comprehensive guidance rate, is the preset target orientation rate, and is the middle value.

[0054] By calculating the comprehensive tool face angle and the comprehensive guidance rate, engineers can quantitatively determine whether they are consistent with the preset target tool face angle and the preset target guidance rate. The preset target tool face angle is a pre-set tool face angle, and the preset target guidance rate is a pre-set guidance rate.

[0055] According to the method provided in the embodiment of the present application, the above method can accurately judge the phenomenon of poor control of the guide tool face and automatically give a warning signal, overcoming the need for manual observation of real-time tool face angle changes in the prior art. When the transmission rate is low, the data density of the real-time tool face angle is low, and it is often unable to accurately display the deviation from the required tool face angle, which can easily cause misjudgment by field engineers. This method can reduce the misjudgment of ground field engineers, increase the success rate of operations, and take corresponding measures in a timely manner in the event of inconsistency. Figure 6 FIG. 4 shows a structural block diagram of a device for determining a steering tool surface control effect of a rotary steering tool according to an embodiment of the present application. Figure 6 As shown, the device comprises: A setting module 601 is adapted to divide 0-360° into a preset number of sectors, and to set two counters for each sector, wherein the two counters of each sector correspond to the guide mode and the direct drilling mode, respectively, and the initial count value of each counter is 0; The processing module 602 is adapted to read the tool face angle and the working mode corresponding to the steering tool face, determine the sector to which the tool face angle belongs, and update the count value of the counter corresponding to the working mode under the sector to which the tool face angle belongs, wherein the working mode includes: steering mode and direct drilling mode; A calculation module 603 is adapted to calculate a first tool face angle and a first steering rate of the steering tool face in the steering mode according to the count value of the counter in the steering mode of each sector in a preset time period, and calculate a second steering rate corresponding to the steering tool face in the direct drilling mode according to the count value of the counter in the direct drilling mode of each sector in the preset time period; The determination module 604 is adapted to determine the control effect of the steerable tool face according to the second steering rate, the first tool face angle and the first steering rate.
